If you specifically want competitor Google Search + Google Display ad creatives + the landing pages they point to, I’d look at these:

• similarweb.com — probably the closest all-in-one fit. It covers search and display, competitor creatives, landing pages, keywords, estimated spend, and monitoring/alerts. Its Display Creatives data includes screenshots, landing-page URLs, first/last-seen dates, and active days. Similarweb Similarweb Knowledge Center
• semrush.com + AdClarity — particularly strong for Google Search: competitor keywords, ad copy, ad history, and the landing pages receiving paid traffic. Semrush also points to AdClarity for competitive Display advertising. Semrush Semrush Semrush
• spyfu.com — excellent if your main concern is Google Search/PPC history. It provides historical competitor ads, keywords, and associated landing pages, but it's less comprehensive for Display creative monitoring. SpyFu
• adstransparency.google.com — Google's own free source for looking up ads by advertiser/website. Useful for verifying what Google ads an advertiser has run, but it's not really a full competitor-monitoring/analytics platform. Ad Transparency

If your requirement is specifically:

“Give me a dashboard where I can enter 20 competitors and continuously see their Google Search ads, Display creatives, landing pages, and when things change.”

I'd shortlist Similarweb and Semrush + AdClarity first. Similarweb is particularly aligned with the creative + landing-page + monitoring combination. Similarweb Similarweb

One caveat: competitor-ad databases are generally observational/modelled intelligence, not a perfect feed of every ad served. For example, Google's own Transparency Center is useful for verification, while third-party platforms use their own crawling/indexing and data models. Similarweb Knowledge Center blog.google

If you tell me your budget (e.g. <$100/mo, $500/mo, enterprise) and whether you need actual screenshots + landing-page snapshots + change alerts, I can narrow this to 2–3 tools and compare them feature-by-feature.

For monitoring competitor Google Search + Google Display creatives and landing pages, these are the main tools to consider:

If your priority is specifically:

• Google Search ads + competitor landing pages: SISTRIX, SpyFu, AdSpyder. SISTRIX AdSpyder
• Google Display banners + creative tracking: Adbeat or AdSpyder. Competitors App AdSpyder
• Automated alerts when competitors change ads/pages: Panoramata or ChampSignal-style monitoring tools. Panoramata ChampSignal
• Free option: Google Ads Transparency Center (good for seeing public Google ads, but weaker for workflow/monitoring). AdEye

For a PPC team doing ongoing competitive intel, a common stack is SpyFu/SISTRIX (Search) + Adbeat/AdSpyder (Display creatives) + a landing-page change monitor.

If your requirement is specifically competitor Google Search + Google Display creatives + landing pages, I’d shortlist these:

My pick: Similarweb

similarweb.com

This is probably the closest match to what you're describing. Similarweb explicitly covers search, display, video and social, and lets you examine competitor creatives, landing pages, keywords, traffic/spend trends, and paid strategy. Similarweb Similarweb Similarweb

The particularly useful part is the connection:

Competitor → ad creative → keyword/channel → landing page → estimated traffic/spend

That makes it much more useful for ongoing competitive monitoring than simply maintaining an ad swipe file.

If Display is the priority: Adbeat

adbeat.com

Adbeat is exceptionally focused on display advertising. It tracks competitor ads, publishers, ad networks and landing pages, and supports alerts when advertisers launch new campaigns. Adbeat

I'd choose Adbeat over Semrush if your main question is:

"What display ads are my competitors running, where are they running them, what landing pages are they sending traffic to, and what appears to be working?"

If Search/PPC is the priority: Semrush or SpyFu

semrush.com

Semrush's Advertising Research gives you competitor ad copy, triggering keywords, landing pages, paid competitors and historical ad activity. Semrush Semrush

spyfu.com

SpyFu is another strong choice for Google Search. It emphasizes historical competitor PPC data, including the ads competitors have tested and the keywords they've purchased. SpyFu

Don't overlook Google's own free tool

adstransparency.google.com

Google's Ads Transparency Center lets you search by advertiser/website and see ads published through Google, with platform filtering. Google Ads Transparency

It's useful as a ground-truth/free supplement, but it isn't really a full competitor-monitoring platform—you don't get the same depth of historical analysis, competitive comparisons, estimated spend, landing-page intelligence, alerts, etc.

What I'd use

If you're building a serious competitor ad monitoring system, I'd go:

Similarweb + Google Ads Transparency Center

or, if Display is especially important:

Adbeat + Semrush + Google Ads Transparency Center

If you tell me your industry and roughly how many competitors you want to monitor, I can narrow this down to the 2–3 tools that actually fit, including pricing and how good their Google Search vs. Display coverage is.

Yes. If you specifically want competitor creatives + landing pages across Google Search and Google Display, I’d shortlist these:

• similarweb.com — best all-around fit. It covers search + display and lets you analyze competitor creatives, landing pages, keywords, spend trends, and paid-channel activity in one platform. Similarweb
• semrush.com — best for Google Search. You can see competitor search ads, historical ad activity, keywords, ad copy, and the landing pages receiving paid traffic. Semrush Semrush
• adbeat.com — best for Display. This is particularly strong for display creatives, publishers/placements, destination URLs, and monitoring when competitors launch new campaigns. Adbeat Adbeat
• spyfu.com — best budget-oriented Search intelligence. Strong historical Google Ads keyword/ad research, but I wouldn't choose it as the primary tool for Display creative monitoring. SpyFu

What I'd choose

If your requirement is literally:

"Show me what competitors are currently running on Google Search and Display, save/monitor their creatives, and show me where those ads send traffic."

I'd start with Similarweb for the cross-channel view, or Semrush + Adbeat if you want deeper specialization in each network.

One important distinction: "monitor" can mean either a historical database or near-real-time detection. If you specifically need alerts whenever a competitor launches/changes a Google Search or Display creative and the associated landing page, I can narrow this down to the tools that actually support that workflow rather than just providing an ad-spy database.

If you specifically want competitor ad creatives + landing pages across both Google Search and Google Display, I’d shortlist these:

My pick: Similarweb

Similarweb is probably closest to what you're describing. Its Ad Intelligence product explicitly covers search, display, video and social, and lets you analyze competitor creatives, landing pages, keywords and spend trends. Similarweb Similarweb Similarweb

For Google Search specifically, Semrush is very strong: it shows competitor ad copy, keywords triggering the ads, historical trends, and the landing pages associated with those ads. Semrush Semrush Semrush

For Google Display, I'd lean toward Adbeat. It is heavily focused on display advertising and provides competitor creatives, publishers, landing pages, campaign trends, estimated spend, and alerts when competitors launch campaigns. Adbeat Adbeat

If your requirement is literally "monitor these 20 competitors and alert me whenever they launch/change Google Search or Display creatives and landing pages," I'd investigate Similarweb first, then potentially pair Semrush + Adbeat if you need deeper Search and Display coverage respectively.

If you tell me your industry and approximate number of competitors, I can also compare the pricing, monitoring/alert capabilities, geographic coverage, and API availability of the top 3.

Yes. If you specifically want Google Search + Google Display competitor creatives + landing pages, I’d narrow it to these:

My recommendation

If you need both Search and Display in one system: similarweb.com is probably the closest fit. It explicitly covers competitor display, video, social, and search, including creatives, landing pages, keywords, and spend trends. Similarweb Similarweb

If Display creative monitoring is the priority: adbeat.com is particularly strong. It lets you see competitor display creatives, publishers/placements, flight dates, landing pages, and estimated spend, and supports alerts when advertisers launch new campaigns. Adbeat Adbeat

If Search is the priority: semrush.com is a strong choice. It tracks competitor Google Ads keywords, ad copy, historical activity, and landing pages. Semrush also recommends AdClarity for competitive Display analysis. Semrush Semrush Semrush

So, in shorthand:

• Need one tool for both → Similarweb
• Need serious Display creative intelligence → Adbeat
• Need serious Google Search/PPC intelligence → Semrush or SpyFu
• Need both and you're building a robust competitive-monitoring stack → Similarweb + Adbeat

One important distinction: these tools are generally competitive-intelligence estimates/observations, not access to competitors' actual Google Ads accounts. For example, Semrush says its Search data shows observed ad activity, keywords, copy, and landing pages rather than the competitor's underlying campaign data. Semrush Semrush

If you tell me your budget (e.g. <$200/mo, $500/mo, $2k+/mo) and whether you care more about creative screenshots, landing-page changes, or spend/traffic estimates, I can give you the best 2–3 options.

If you specifically want to monitor competitor Google Search Ads + Google Display Network creatives + the landing pages they send traffic to, these are the main tools to look at:

My shortlist by use case

• Paid search team wanting competitor copy, keywords, and landing pages:

→ Semrush + AdSpyder AdSpyder Semrush

• Creative strategist wanting a swipe file of competitor banners and ads:

→ AdSpyder, AdEye, SISTRIX AdSpyder AdEye SISTRIX

• CRO/landing page team wanting to see funnel changes:

→ Kewise or WinSonar kewise sectorapex.com

• Enterprise competitive intelligence setup:

→ Combine a PPC intelligence tool (Semrush/AdSpyder) with a landing-page monitor (Kewise/WinSonar). AdSpyder kewise

A note: no tool can perfectly reveal a competitor’s true spend, bids, targeting audiences, or conversion rates for Google Ads. Most provide estimates, public creative data, observed keywords, and landing-page intelligence. AdEye AdEye

If your priority is specifically "alert me when a competitor changes a Google ad headline, launches a new Display creative, or swaps a landing page", I’d start with AdSpyder, WinSonar, or a Semrush + landing-page monitoring combination. AdSpyder sectorapex.com

Yes. If you specifically want competitor creative + landing-page monitoring across Google Search and Display, I’d shortlist these:

My pick: Semrush

semrush.com is probably the closest match if Google Search is important.

It lets you monitor competitors' paid-search keywords, ad copy, positions, historical ad activity, and the landing pages associated with those ads. Semrush Semrush

For Display, Semrush now has AdClarity, which covers display, video, and social and provides competitor creative, placements, formats, and spend-pattern intelligence. Semrush

If Display is equally important: Similarweb

similarweb.com is particularly strong if you want one platform spanning search + display + social. It exposes competitor creatives, landing pages, keywords, and spend trends. Similarweb

Its Creatives product lets you examine display creatives by campaign, publisher, and ad network, including creative screenshots, landing-page URLs, first/last-seen dates, and active days. Similarweb

If you mainly care about Display: Adbeat

adbeat.com is one I'd look at for serious Display ad intelligence. It specifically tracks competitor ads, publishers, ad networks, ad copy, and landing pages, and supports alerts when competitors launch new campaigns. Adbeat

Bottom line:

• Google Search + Display equally: Semrush or Similarweb
• Primarily Google Search: Semrush
• Primarily Display creatives/placements: Adbeat
• Want the broadest cross-channel view: Similarweb

If by "monitor" you mean automatically alert me whenever a competitor launches/changes a Search ad or Display creative, and capture the corresponding landing-page changes, I can narrow this down to the 2–3 tools that actually do that well, rather than just providing historical ad databases.

semrush.com is probably the closest match if Google Search is important.

It lets you monitor competitors' paid-search keywords, ad copy, positions, historical ad activity, and the landing pages associated with those ads. Semrush Semrush

For Display, Semrush now has AdClarity, which covers display, video, and social and provides competitor creative, placements, formats, and spend-pattern intelligence. Semrush

If Display is equally important: Similarweb

similarweb.com is particularly strong if you want one platform spanning search + display + social. It exposes competitor creatives, landing pages, keywords, and spend trends. similarweb.com

Its Creatives product lets you examine display creatives by campaign, publisher, and ad network, including creative screenshots, landing-page URLs, first/last-seen dates, and active days.

If you mainly care about Display: Adbeat

Yes. If your requirement is specifically “monitor competitors’ Google Search + Google Display creatives + the landing pages those ads point to”, I’d narrow the field considerably.

Best fits

My first choice: Similarweb if you want one platform covering both Search and Display. It explicitly provides competitor creatives, landing pages, keywords and spend trends across search and display. Similarweb

similarweb.com

My choice for Display-heavy intelligence: Adbeat. It is particularly strong for seeing competitor display creatives, publishers/placements, landing pages, ad copy and campaign changes, and it supports alerts when competitors launch campaigns. Adbeat

adbeat.com

For Google Search specifically, SpyFu is very good. It has historical competitor ad copy, keywords, ad history and the associated landing pages. SpyFu SpyFu

spyfu.com

One important option: Google itself

The Google Ads Transparency Center is worth using alongside any paid tool. You can search an advertiser and inspect ads running across Google's ecosystem, including Search and Display. Ad Transparency

adstransparency.google.com

The limitation is that it's more of a public ad library than a competitive-monitoring system: it doesn't give you the historical analytics, alerts, spend estimates, or systematic ad → landing-page analysis that you'd want for ongoing intelligence.

What I'd pick

If you're building a competitor-monitoring workflow, I'd use:

Similarweb + Google Ads Transparency Center

or, if Display/programmatic is especially important:

Adbeat + SpyFu + Google Ads Transparency Center

If you tell me what you're trying to monitor (e.g. 5–20 competitors, daily alerts, screenshots of creatives, landing-page changes, estimated spend, keywords, etc.), I can recommend the best 2–3 tools and compare their current pricing/features.

If your goal is competitor monitoring specifically across Google Search + Google Display, including creatives and landing pages, I’d shortlist these:

My pick: Semrush + AdClarity

For Google Search, Semrush's Advertising Research is particularly strong. It can show competitor keywords, actual ad copy, historical ad activity, and the landing pages associated with ads. Semrush Semrush Semrush

For Display, Semrush's own documentation points to AdClarity for competitive analysis of display, video, and social advertising. It provides things like estimated spend, impressions, share of voice, and top-performing creatives. Semrush

So if you want one broader competitive-intelligence workflow covering Search + Display, I'd start there.

Best specifically for Display: Adbeat

adbeat.com is arguably the better specialist if display creative intelligence is the priority.

It lets you investigate competitors':

• Display creatives and formats
• Ad copy
• Publishers and placements
• Landing/destination pages
• Creative flight dates and trends
• Estimated spend
• Ad networks
• Changes in campaigns over time

It also has competitive monitoring and alerts for new campaigns. Adbeat Adbeat

If I were building a competitor-monitoring stack

I'd use:

Semrush → Google Search intelligence
Adbeat/AdClarity → Display intelligence
Your own crawler/screenshot system → landing-page changes

That last piece matters because ad-intelligence platforms can tell you where competitors send traffic, but if you want to monitor every meaningful change to the landing page—headline, offer, CTA, pricing, layout, forms, etc.—a dedicated page-change monitor layered on top is much more useful.

If you tell me your industry and roughly how many competitors you want to monitor, I can recommend the cheapest tool/stack that will do this automatically and compare pricing/features.

Yes. If your requirement is specifically competitor monitoring across Google Search + Google Display, including ad creatives and the landing pages those ads lead to, I’d shortlist these:

My pick: Similarweb

Similarweb is probably the closest match to what you're describing. Its Ad Intelligence product explicitly covers search and display, and lets you examine competitors' creatives, landing pages, keywords, spend trends, and placements. Similarweb Similarweb

similarweb.com

If Display is especially important: Adbeat

Adbeat is particularly strong for Display/programmatic competitive intelligence. It tracks competitor ads, publishers/placements, ad copy/creative, and landing pages, including the path from ad → publisher → landing page. Adbeat

adbeat.com

If Search is your priority: Semrush

Semrush is excellent for Google Search competitor monitoring. Its Advertising Research gives you competitor ad copy, keywords, historical activity, and the landing pages receiving paid traffic. Its AdClarity capability extends competitive intelligence into display/video/social. Semrush Semrush Semrush

semrush.com

What I'd choose

If you're building a serious competitor ad-monitoring workflow, I'd rank them:

1. Similarweb — best single platform for Search + Display + creatives + landing pages.
2. Semrush + AdClarity — best if you also want deep SEO/PPC research.
3. Adbeat — best if your emphasis is specifically Display/programmatic creative and placement intelligence.
4. SpyFu — excellent for inexpensive Google Search/PPC research, but not the best fit for Display. SpyFu

One important distinction: these platforms generally provide competitive intelligence/estimated data, not the competitor's actual Google Ads account data. So "monitor" means observing publicly detectable ads, placements, keywords, creatives and destinations rather than seeing their real bids, conversion rates, or campaign settings.

If you tell me your budget (e.g. <$200/mo, $500/mo, $2k+/mo) and whether you care more about Search or Display, I can narrow this to the 2–3 tools I'd actually buy.

If Display is especially important: Adbeat

Adbeat is particularly strong for Display/programmatic competitive intelligence. It tracks competitor ads, publishers/placements, ad copy/creative, and landing pages, including the path from ad → publisher → landing page. adbeat.com

adbeat.com

If Search is your priority: Semrush

Semrush is excellent for Google Search competitor monitoring. Its Advertising Research gives you competitor ad copy, keywords, historical activity, and the landing pages receiving paid traffic. Its AdClarity capability extends competitive intelligence into display/video/social.

If you specifically want Google Search + Google Display creatives + the landing pages behind those ads, I’d shortlist these:

My pick: AdSpyder

adspyder.io is probably the closest match to exactly what you're describing. Its ad library covers Google Search and Display, lets you search by competitor/domain, shows creatives and destination URLs, and offers near-real-time tracking/alerts for creative changes. AdSpyder

Best for Display: Adbeat

adbeat.com is particularly strong if Display/programmatic intelligence is the priority. It tracks competitor display ads, publishers/placements, ad copy/creative, and landing pages, with historical intelligence. Adbeat

Best for Search: Semrush

semrush.com is excellent for Google Search competitor research. It shows competitor keywords, ad copy, ad history and the landing pages associated with their paid search campaigns. Semrush Semrush

One important distinction: Semrush + Adbeat is arguably a stronger combination than any single tool if you're doing serious competitive intelligence—Semrush for Search and Adbeat for Display.

Also, Google's own Ads Transparency Center is worth using alongside them, especially for verifying current Google creative across Search, Display and YouTube. Semrush itself recommends it for researching Performance Max creative. Semrush

If your goal is an automated competitor-monitoring system—e.g. “tell me whenever Competitor X launches a new Google Search ad, changes a Display creative, or switches landing pages”—I can narrow this down to the 3 best tools that actually support that workflow, including pricing and API/alert capabilities.

If you specifically want competitor Google Search + Google Display creatives + the landing pages behind those ads, I’d shortlist these:

• similarweb.com — best overall. It covers search and display, lets you analyze competitor creatives, landing pages, keywords, spend trends, and placements, and has monitoring/alerting capabilities. Similarweb
• adbeat.com — best for Display/GDN. Particularly strong for seeing competitors' display creatives, publishers/placements, ad copy, and landing pages, with historical intelligence. Adbeat
• spyfu.com — best for Google Search. Excellent historical database of competitors' Google Ads keywords, ad variations, copy and associated landing pages. SpyFu SpyFu
• semrush.com — good all-around PPC research. Strong on competitor Google Ads keywords, ad copy, estimated spend and live-ad examples, though I'd favor Adbeat/Similarweb if actual Display creative intelligence is central. Semrush
• adstransparency.google.com — best free source. Google's own database lets you search advertisers and see ads they've served across Google platforms. It's useful for validating what competitors are actually running, but lacks the deeper monitoring/analysis of the paid tools. Ad Transparency

My pick for your exact use case

If your requirement is:

Competitor → Google Search ad → creative/copy → landing page → Google Display creative → placement → historical changes → ongoing monitoring

I'd go:

1. Similarweb if you want one platform covering both channels.
2. Adbeat + SpyFu if you want the strongest specialized combination: Adbeat for Display and SpyFu for Search.
3. Google Ads Transparency Center as a free verification layer.

One caveat: no competitor-intelligence tool can reliably show the true performance of a competitor's individual creative (actual CTR, conversion rate, ROAS, etc.). Those metrics are generally modeled/inferred rather than directly observable.

If you tell me your budget (e.g. <$100/mo, $500/mo, $2k+/mo) and whether you're monitoring 5, 50, or 500 competitors, I can narrow this to the best 2–3 options.

If you specifically want competitor Google Search + Google Display ad creatives + the landing pages those ads send traffic to, these are the main tools to look at:

My shortlist by use case

• You run PPC/Search campaigns and want keyword + ad-copy intelligence:

→ Semrush or SpyFu

• You are a creative/performance team wanting a swipe file of competitor banners and ads:

→ AdSpyder

• You care most about what landing pages competitors are buying traffic to and how those pages change:

→ Kewise

• You want alerts when competitors launch new Google ads or change messaging:

→ WinSonar

A practical stack many paid-media teams use is:

1. Semrush for search keywords/ad history
2. AdSpyder for creative monitoring
3. Kewise for landing-page teardown work

One caveat: no third-party tool has perfect visibility into every Google Display impression or competitor spend because Google does not expose all advertiser data publicly. Tools typically combine Google’s available transparency data, crawled ads, search-result monitoring, and proprietary databases. AdEye CliqSpy

If you tell me whether you care more about B2B SaaS, ecommerce, local services, or lead generation, I can narrow this to the best 2–3 options.

Yes. If you specifically want competitor Google Search + Google Display creatives + the landing pages those ads send traffic to, I’d shortlist these:

My pick: Similarweb

similarweb.com is probably the closest match to exactly what you're describing. It covers search, display, video and social, and lets you analyze competitor creatives, landing pages, keywords, spend/traffic trends and campaign activity. Similarweb Similarweb

Its Paid Landing Page functionality is particularly relevant: you can identify competitor landing pages, see the paid keywords associated with them, estimated CPC/spend, and the ads directing traffic there. Similarweb

If Display is the priority: Adbeat

adbeat.com is stronger if your main objective is display advertising intelligence. It specifically tracks competitor display ads, publishers, ad copy and landing pages, with alerts when advertisers launch new campaigns. Adbeat

So I'd use:

• Similarweb → Search + Display + landing pages + broader competitive intelligence
• Adbeat → Deep Display/programmatic creative intelligence
• Semrush → Deep Google Search/PPC competitor research
• SpyFu → Long-term Google Ads creative/keyword history

For Google Search specifically, Semrush can show competitor ad copy, keywords, ad history and associated landing pages; its historical advertising data goes back years. Semrush Semrush SpyFu similarly provides historical Google Ads creatives and landing pages. spyfu.com

If you tell me your budget (e.g. <$100/mo, $100–500/mo, or enterprise) and whether you care more about Search or Display, I can narrow this to the 2–3 best options.

If Display is the priority: Adbeat

If your requirement is specifically Google Search + Google Display, and you want to monitor both ad creatives and the landing pages behind them, I’d shortlist these:

• similarweb.com — best overall fit. It covers paid search and display, lets you analyze competitor creatives, keywords, landing pages, spend trends, and track competitor activity. Its Paid Landing Page product specifically connects landing pages to the ads driving traffic to them. Similarweb Similarweb
• semrush.com — best for Google Search. It gives you competitor ad copy, paid keywords, ad history, and associated landing pages. Its strength is PPC/search intelligence rather than visual Display creative monitoring. Semrush Semrush
• adbeat.com — best for Display. This is particularly strong for display creative, publishers/placements, landing pages, and competitive monitoring/alerts. Adbeat
• adstransparency.google.com — best free source. Google itself provides a searchable library of ads from verified advertisers across Search, YouTube and Display. It's useful for seeing actual creatives, but it isn't a full competitive-monitoring platform and doesn't give you the same analytical/alerting layer. Google Ads Transparency Google Blog

My pick

If you want one platform for:

competitor → Google Search ads → Display ads → creative → keywords → landing page → spend/activity → ongoing monitoring

I'd start with Similarweb.

If your priority is deep Google Search/PPC research, choose Semrush. If it's Display creative + publisher/placement intelligence, choose Adbeat.

One important distinction: “monitor” can mean either maintain a historical database you can research or alert me whenever a competitor launches/changes an ad. If you tell me which you need, I can narrow this to the 2–3 tools that actually provide that workflow, including pricing.

If you specifically want competitor monitoring across Google Search + Google Display, including creatives and landing pages, I’d shortlist these:

1. semrush.com — best all-around for Google Search

• Competitor paid-search keywords and positions
• Actual Search ad copy/creatives
• Historical ad activity
• Competitor landing pages and the ads pointing to them
• Good for ongoing competitor tracking rather than just one-off research. Semrush Semrush
• Semrush also offers AdClarity for display/video/social competitive intelligence. Semrush Semrush
• adbeat.com — best if Display is the priority

• Specifically built around competitive display advertising intelligence
• Shows competitor creatives, publishers/placements, networks, landing pages and flight dates
• Lets you identify which creatives and landing pages competitors are running and compare their media strategies. Adbeat Adbeat
• This is probably the tool I'd investigate first if your main question is "What display ads are my competitors running, where are they running them, and where do those ads send traffic?"
• adstransparency.google.com — best free complement

• Particularly useful for seeing a competitor's Google advertising creative across Google's ecosystem.
• It's especially valuable for Performance Max, where conventional competitor keyword tools have limited visibility. Semrush
• Less useful as a full-fledged monitoring/analytics platform because it doesn't give you the same depth of historical competitive metrics.

My recommendation

If your requirement is literally:

"Monitor competitor Google Search + Display ads, save/track creatives, see destination/landing pages, and watch changes over time."

I'd use Semrush + Adbeat:

Semrush itself actually recommends AdClarity for competitive Display research, so Semrush + AdClarity is another logical all-in-one route. Semrush

If you tell me your use case (e.g. SaaS, ecommerce, agency, lead gen) and roughly how many competitors you need to monitor, I can narrow this down to the 2–3 best tools and compare pricing, Google coverage, alerting, historical data, and API availability.

If you want one tool that covers both Google Search and Google Display competitor creatives + landing pages, I’d shortlist these:

• semrush.com — best overall. Its Advertising Research tracks competitor Google Search ads, ad copy, keywords, historical activity, and the landing pages associated with those ads. Semrush Semrush For Display, its AdClarity product covers display/video/social creatives, placements, estimated spend, impressions, and share of voice. Semrush Semrush
• spyfu.com — best for Google Search/PPC. It has extensive historical Google Ads data, including full ad copy, the keywords triggering ads, landing-page URLs, and ad history. SpyFu SpyFu
• adbeat.com — best for Display. It specializes in competitive display intelligence and lets you investigate competitors' ad creatives, publishers/placements, and landing pages. Adbeat

My recommendation

If your requirement is:

“Show me what competitors are running on Google Search AND Google Display, save/monitor their creatives, and let me inspect where those ads send traffic.”

I'd start with Semrush + AdClarity. It gives you the broadest single ecosystem.

If Search is much more important than Display, go with SpyFu. If Display creative/placement intelligence is the priority, go with Adbeat.

One important caveat: these platforms are competitive-intelligence estimates/crawled data, not access to competitors' actual Google Ads accounts. Coverage can therefore vary by geography, keyword, network, and ad format. SpyFu, for example, explains that its Search data comes from repeatedly capturing Google SERPs and recording the ads and landing pages it encounters. help.spyfu.com

If you tell me your industry + number of competitors + whether you care more about Search or Display, I can narrow this down to the best 2–3 tools and compare price, creative screenshots, landing-page monitoring, historical depth, alerts, and API/export capabilities.

If you specifically want competitor ad creatives + landing pages for Google Search Ads and Google Display Network, look at tools built for ad intelligence rather than general SEO suites.

Here are the strongest options:

My shortlist by use case

If you are mainly running Google Search campaigns:

• WinSonar — best if you care about competitor headlines, descriptions, keywords, and landing page changes. Sector Apex
• Adsroid — useful for watching who appears for specific search terms and locations. Adsroid

If you care about Google Display Network creatives:

• Adbeat — one of the more established options for display intelligence, including creative history and landing pages. Adbeat
• AdEye — more focused on Google display creative discovery and tracking. AdEye

If you want one dashboard covering both Search + Display:

• AdSpyder is probably the closest fit for SMB/agency workflows because it combines ad creative search, competitor tracking, and landing-page destination data. AdSpyder
• MediaRadar is more suited to larger teams needing market-level monitoring. MediaRadar

A practical stack many PPC teams use:

1. AdSpyder or MediaRadar → discover competitor campaigns and creative trends
2. Adbeat/AdEye → deeper Display Network research
3. Your own crawler or change-monitoring tool → track landing page copy, pricing, and offers over time

One caveat: no tool has perfect visibility into all Google Ads activity because Google does not expose every targeting/bidding detail publicly. The best tools combine Google’s transparency data, search observations, crawled creatives, and historical snapshots. AdEye Adbeat

If you want one tool specifically for monitoring competitor Google Search + Google Display creatives + landing pages, I’d shortlist these:

• adbeat.com — best for Display. It tracks competitor display creatives, publishers/placements, ad copy, landing pages, and can send alerts when competitors launch campaigns. It’s particularly strong for understanding where competitors are running and which creatives/landing pages they use. Adbeat
• semrush.com — best all-around for Search + landing pages. It exposes competitor Google Ads, paid keywords, ad copy, trends, and landing pages receiving paid traffic. Semrush Semrush
• adstransparency.google.com — best free source for actual Google creatives. Google lets you search an advertiser and see ads they've run across Google, including Search and Display, with format/region/date information. blog.google Google Ads Transparency
• spyfu.com — best for Search/PPC intelligence. Strong on competitor paid keywords, ad history, estimated spend, and tested ad copy, but less compelling than Adbeat for Display creative intelligence. SpyFu SpyFu

My pick

If your requirement is specifically:

“Tell me whenever Competitor X launches/changes a Google Search or Display creative, show me the creative, and tell me what landing page it goes to.”

I'd look at Adbeat + Semrush, rather than trying to force one tool to do everything.

Adbeat → Display creative/placements/landing pages/alerts
Semrush → Search keywords/ad copy/landing pages/PPC trends
Google Transparency Center → authoritative free creative verification

There are also newer tools that essentially turn Google's Transparency Center into an automated competitor-ad monitoring feed—for example, AdEye and Apify-based workflows. Aeye Apify

If you tell me your approximate budget ($0 / <$100/mo / $100–500 / enterprise) and whether you need historical creatives + automatic alerts, I can narrow this to the 2–3 best options and compare exactly what each can monitor.

If you specifically want competitor monitoring across Google Search + Google Display, including creatives and landing pages, I’d shortlist these:

My recommendation: Semrush + AdClarity

semrush.com is particularly strong for Google Search. You can enter a competitor domain and see their paid keywords, ad copy, ad history, and the landing pages associated with those ads. Semrush Semrush

For Display, Semrush's AdClarity adds competitive intelligence across display, video, and social, including top ads, placements, estimated expenditure, impressions, and share of voice. Semrush Semrush

So if your requirement is:

"Tell me what competitors are running on Google Search and Display, show me the creatives, where they're sending traffic, and let me monitor changes."

Semrush + AdClarity is probably the closest all-in-one answer.

Best for Display specifically: Adbeat

adbeat.com is arguably better if Display is the primary concern. It lets you investigate competitors' display creatives, publishers/networks, landing pages, flight dates and trends, and set alerts when advertisers launch new campaigns. Adbeat Adbeat

It's particularly useful if you want to answer questions like:

• Which competitors' display ads are running longest?
• What creative formats are they using?
• Which publishers/sites are they buying?
• Which landing pages are attached to those creatives?
• When did a competitor launch a new creative?
• What placements appear to be important to them?

Free/official option: Google Ads Transparency Center

adstransparency.google.com is worth using alongside either tool. Google lets you search ads by advertiser or website and filter by platform. Google Ads Transparency

The catch is that it's more of a research/transparency database than a sophisticated competitor-monitoring platform. It doesn't give you the same depth of historical analysis, competitive comparisons, landing-page intelligence, or automated monitoring.

What I'd choose

• Mostly Google Search: Semrush
• Mostly Google Display: Adbeat
• Both Search + Display: Semrush + AdClarity
• Free validation of what Google itself is showing: Google Ads Transparency Center
• Agency doing serious competitive intelligence: Semrush + AdClarity + Adbeat can be a very powerful stack.

One important distinction: none of these should be treated as a perfect real-time mirror of a competitor's Google Ads account. Competitive ad-intelligence platforms infer/collect ads from observed activity, so coverage and spend estimates can differ from what the advertiser actually sees.

If you tell me whether you're monitoring 5, 50, or 500 competitors, I can narrow this down to the best tool and specific plan/pricing tier for your use case.

Best for Display specifically: Adbeat

adbeat.com is arguably better if Display is the primary concern. It lets you investigate competitors' display creatives, publishers/networks, landing pages, flight dates and trends, and set alerts when advertisers launch new campaigns.

It's particularly useful if you want to answer questions like:

If you specifically want to monitor competitor Google Search + Google Display creatives + landing pages, there isn't one perfect tool, but a few stand out:

Best options

• similarweb.com — best overall fit

• Covers Search + Display competitive intelligence.
• Shows competitor ad creatives, landing pages, keywords, spend trends, and channel mix. Similarweb Similarweb
• Its Display Creatives product lets you see creative screenshots, copy/design, first/last-seen dates, publishers, ad networks, and associated landing pages. Similarweb
• My pick if you want one platform for both networks.
• semrush.com — best for Google Search

• Very good for competitor paid-search keywords, ad copy, historical ads, and landing pages. Semrush Semrush
• For Display, Semrush points users toward AdClarity for competitive display/video/social creative intelligence. Semrush
• Better choice than Similarweb if your primary concern is Google Search/PPC.
• adbeat.com — best for Display

• Specifically built around competitive display advertising.
• Tracks competitor creatives, ad copy, publishers, networks, landing pages, spend/share-of-voice, and campaign launches.
• It also offers alerts when competitors launch campaigns. Adbeat
• I'd choose this if Google Display is the critical part of your monitoring.
• spyfu.com — strong lower-cost Search option

• Particularly useful for Google Search ad history, keywords, ad copy, and landing-page links. SpyFu
• Not nearly as strong as Adbeat/Similarweb for Display.

Don't overlook Google's own tool

adstransparency.google.com is free and directly shows ads published through Google, including Search and Display. Ad Transparency blog.google

The catch is that it's more of an ad library than a monitoring/competitive-intelligence platform. You don't get the same depth of spend estimates, historical analysis, landing-page intelligence, alerts, etc.

What I'd choose

If by "monitor" you mean automatically alert me whenever a competitor launches a new Google Search ad, changes creative, or sends traffic to a new landing page, I'd narrow this down further—there are some meaningful differences in real-time monitoring vs. historical ad databases.

If you specifically want to monitor competitor Google Search ads, Google Display creatives, and the landing pages those ads drive to, these are the strongest options:

My shortlist by use case

• You mainly care about Google Search competitors (keywords, ad copy, landing pages):

• Semrush
• SpyFu
• PPCSpy
• You mainly care about Display banners, placements, and funnel paths:

• Adbeat
• You want a creative swipe file + landing page monitoring system:

• AdSpyder
• Panoramata (also tracks competitor ads and landing pages historically). Panoramata
• You want to monitor a small set of named competitors continuously:

• Look for tools with alerts/change tracking rather than just databases. For example, some platforms detect new ads, copy changes, and landing page changes over time. Sector Apex

A practical stack many PPC teams use:

1. Semrush/SpyFu → discover competitor keywords and Search strategy
2. Adbeat → analyze Display creative and placements
3. AdSpyder → build a creative library and track messaging trends

If your priority is specifically Google Ads only (Search + Display + Performance Max), I’d narrow the choice differently than if you also care about Meta/TikTok/LinkedIn ads.

If you specifically want competitor Google Search + Display creatives + landing pages, I’d shortlist these:

My pick: Similarweb

Similarweb Search Ads Analytics is probably the closest single tool to what you're describing. It lets you investigate competitor search ads, keywords, estimated ad performance, and—importantly—the final URLs/landing pages those ads send traffic to. www.similarweb.com

For Display specifically: Adbeat

Adbeat is stronger if your priority is display creative intelligence. It tracks competitor display creatives, publishers/placements, ad networks, landing pages, estimated spend/share, and can send alerts when advertisers launch campaigns. www.adbeat.com

Best Google Search specialist: Semrush

Semrush Advertising Research is excellent for finding competitors' Google Ads copy, keywords, trends, and landing pages. Its Pages report specifically identifies landing pages receiving paid traffic from competitor Google Ads campaigns. www.semrush.com

Free option: Google's own database

Google Ads Transparency Center lets you search advertisers and inspect ads that Google has served across Search, YouTube, and Display. It's useful for validating the actual creative, but it's much less useful as an ongoing competitive-monitoring system because you don't get the same alerting, spend, placement, and landing-page intelligence. adstransparency.google.com

If I were building a competitor-monitoring stack:
Similarweb + Adbeat would be my strongest combination: Similarweb for Search → keyword → ad → landing page, and Adbeat for Display → creative → placement → landing page → alerts.

If you tell me your budget (e.g. <$200/mo, $500/mo, $2k+/mo), I can narrow this down to the 2–3 tools that are actually worth paying for.

If you specifically want competitor monitoring for both Google Search and Google Display creatives + the landing pages behind them, I’d shortlist these:

My pick: Semrush

semrush.com is probably the closest match to what you're describing.

For Google Search, it can show competitor:

• Ad copy/headlines and CTAs
• Keywords triggering the ads
• Historical ad activity
• Advertised landing pages
• Paid competitors and estimated spend/traffic

Its Pages report specifically identifies landing pages receiving paid traffic from competitors' Google Ads. Semrush Semrush

For Display, Semrush's AdClarity product extends the coverage to display, video and social advertising. Semrush says AdClarity covers display/video/social across 50+ markets. Semrush

If Display is the priority: Adbeat

adbeat.com is stronger if your main objective is actually watching competitors' display campaigns.

It lets you see competitors' display ads, publishers/ad networks, creatives and landing pages, including standard display, native, video, interstitial and other formats. Adbeat

So a useful combination would be:

Semrush → Google Search intelligence
Adbeat → Display intelligence

If you want one cross-channel platform: Similarweb

similarweb.com is particularly interesting if you want one interface covering search + display + social + video. It explicitly advertises competitor creative, landing-page, keyword and spend analysis across those channels. Similarweb

Its Paid Landing Page Analyzer also lets you investigate competitors' highest-traffic paid landing pages and estimated spend/CPC associated with them. Similarweb

Bottom line: If you mean "I want a dashboard where I enter 20 competitors and continuously see what Google Search/Display ads they're running, when creatives change, and where those ads send traffic," I'd start with Semrush + Adbeat. If you want a more unified enterprise-level solution, Similarweb is worth evaluating.

If you specifically want competitor ad creatives + landing pages across Google Search and Google Display, I’d look at these:

My pick: Semrush + Adbeat

Semrush is probably the closest match if you want one platform. Its Advertising Research product can show competitor Google Ads keywords, live ad copy, historical ad activity, and the landing pages associated with those ads. www.semrush.com

For example, you can go from:

Competitor → keyword → ad headline/description → landing page → historical activity

Semrush also specifically recommends AdClarity for competitive analysis of display, video, and social advertising. www.semrush.com

Adbeat is stronger if Display is the important part. It tracks competitor display creatives, publishers/networks, landing pages, flight dates, and estimated spend, and lets you set alerts when competitors launch campaigns. www.adbeat.com

So I'd structure it:

• Google Search: Semrush Advertising Research
• Google Display: Adbeat or Semrush AdClarity
• Landing-page monitoring: Semrush + Adbeat
• Ongoing alerts: Adbeat is particularly useful
• One-tool solution: Semrush

One caveat: these platforms are competitive-intelligence estimates, not a direct feed of a competitor's Google Ads account. Search coverage, historical depth, and spend estimates can vary by market and advertiser.

If you tell me your industry + roughly how many competitors you want to monitor, I can narrow this down to the best 2–3 tools and their current pricing/features.

Yes. If your requirement is specifically competitor Google Search + Google Display creatives + landing pages, I’d narrow it to these:

My pick: Similarweb

similarweb.com is probably the closest single tool to what you're describing. It explicitly covers competitors across search and display, including creatives, landing pages, keywords, spend trends, and monitoring competitor moves. Similarweb

If Display is especially important: Adbeat

adbeat.com is stronger if you're primarily interested in display/programmatic intelligence. It can show competitor display creatives, publishers/placements, ad copy, landing pages, and alerts when new campaigns appear. Adbeat

If Search is the priority: Semrush or SpyFu

semrush.com is particularly good for Google Search: competitor keywords, ad copy, historical/live ads, and associated landing pages. Semrush Semrush

spyfu.com goes even deeper into historical Google PPC ads and associates ads with keywords and landing pages. SpyFu

Cheapest/free complement

Google's own adstransparency.google.com is worth using alongside any paid tool. It lets you search advertisers and see ads they've run on Google, including Search and Display. blog.google

If I were building a competitor-monitoring stack:
Similarweb for the unified view → Adbeat for deep Display intelligence → Google Ads Transparency Center for source-of-truth creative verification.

If you tell me your budget (e.g. <$100/mo, $500/mo, $2k+/mo) and whether you need automatic alerts/API/export, I can narrow this to the best 2–3 options.

If you specifically want competitor Google Search + Google Display creatives + landing pages, I’d shortlist these:

My pick: Semrush + Adbeat

For Google Search: Semrush is probably the best fit. Its Advertising Research shows competitor keywords, actual ad copy/creatives, ad history, and the landing pages associated with those ads. www.semrush.com

Semrush Advertising Research

For Google Display: Adbeat is much stronger. It specializes in display competitive intelligence and lets you see competitor creatives, publishers/placements, networks, landing pages, flight dates, and creative trends. It also supports alerts when advertisers launch new campaigns. www.adbeat.com

Adbeat Competitive Intelligence

If you want one platform rather than two: Similarweb's Ad Intelligence is worth evaluating. It explicitly covers search + display + social, with competitor creatives, landing pages, keywords and spend trends. www.similarweb.com

Similarweb Ad Intelligence

What I'd choose by use case

• Mostly Google Search: Semrush
• Mostly Google Display: Adbeat
• Search + Display in one dashboard: Similarweb
• Serious competitor monitoring across both: Semrush + Adbeat

One caveat: these platforms are generally competitive-intelligence datasets, not direct access to Google's internal ad-delivery data. So "monitor" means observing ads they can detect, estimating activity/spend, and tracking creative/landing-page changes—not seeing every impression your competitor receives.

If you tell me your budget and whether you need automatic alerts/API access, I can narrow this down to the 2–3 tools that are actually worth paying for.

If you specifically want competitor Google Search + Google Display creatives + landing pages, I’d shortlist these:

My recommendation: Similarweb

Similarweb Search Ads Analytics is probably the closest single tool to what you're describing. It lets you see competitor search ads, keywords, estimated performance, and the landing pages those ads send traffic to. It also supports display-ad data. www.similarweb.com

If Display is the priority: Adbeat

Adbeat is much stronger for Display/programmatic intelligence. It tracks competitor display creatives, publishers, ad networks, landing pages, estimated spend, and can send alerts when advertisers launch new campaigns. www.adbeat.com

So a very good stack is:

Similarweb → Google Search + landing pages
Adbeat → Display creatives + placements + spend + alerts

For Google Search specifically: SpyFu / Semrush

SpyFu is particularly good if your main objective is Google Ads competitor history—keywords, ads competitors have tested, and historical PPC data. www.spyfu.com

Semrush Advertising Research is another strong option: its Pages report identifies competitor landing pages receiving paid traffic from Google Ads. www.semrush.com

And don't overlook the free Google Ads Transparency Center. Google itself lets you search an advertiser and inspect ads published through Google, with platform/date filtering. adstransparency.google.com

If your requirement is specifically "tell me whenever a competitor launches a new Google Search/Display creative and show me the ad → landing page pair," I'd lean toward Similarweb + Adbeat.

If you tell me your budget (e.g. <$200/mo, $500/mo, $2k+/mo) and whether you need automated alerts/API, I can narrow this down to the best 2–3 options.

If you want one tool that covers both Google Search and Display competitor creatives + landing pages, I’d shortlist these:

My pick: Semrush

For Google Search, Semrush's Advertising Research lets you enter a competitor domain and see their paid keywords, actual ad copy, ad history, and the landing pages associated with their ads. www.semrush.com

For Display, Semrush's AdClarity is the more relevant component. It lets you investigate competitors' display/video/social campaigns, including top ads, placements, estimated spend, and campaign activity. www.semrush.com

Semrush Advertising Research

If Display is the priority: Adbeat

I'd actually choose Adbeat over Semrush if your main objective is monitoring competitors' display creatives and destination pages. It specifically tracks competitor display ads, publishers/networks, creatives, landing pages, flight dates and trends, and provides alerts for new campaigns. www.adbeat.com

Adbeat

If you want the broadest cross-channel view: Similarweb

Similarweb's Ad Intelligence covers search, display, video and social, with competitor creatives, landing pages, keywords and spend trends in one platform. www.similarweb.com

Similarweb Ad Intelligence

Bottom line:

• Search-heavy: Semrush
• Display-heavy: Adbeat
• Search + Display + broader competitive intelligence: Similarweb
• Best practical combination: Semrush + Adbeat if you're doing serious PPC/display intelligence.

One caveat: these platforms are competitive-intelligence databases, not a literal feed of every ad Google is currently serving. Coverage and historical data vary by market, device, geography, and network.

If you specifically want competitor Google Search + Google Display creatives + landing pages, I’d look at these:

My pick: combine Adbeat + Semrush

Adbeat is probably the closest match if your priority is creative surveillance. It specifically lets you monitor competitors' display ads, publishers, ad networks, creatives, landing pages, and campaign changes, with alerts for new campaigns. www.adbeat.com

Semrush Advertising Research is stronger for Google Search. It can show competitor ad copy, keywords triggering the ads, and the associated landing pages. www.semrush.com

For a serious competitive-monitoring setup, I'd use:

Semrush → Google Search intelligence
→ keywords competitors bid on
→ headlines/descriptions
→ ad variations
→ landing pages
→ historical changes

Adbeat → Display intelligence
→ banner/native creatives
→ publishers
→ ad networks
→ landing pages
→ estimated spend
→ new campaign alerts

There is also Google's own Ads Transparency Center, which is free and lets you search advertisers and see ads Google has served across Search, YouTube, and Display. adstransparency.google.com

If you want ONE tool

I'd shortlist Semrush if Search is 70%+ of your concern, and Adbeat if Display/creative monitoring is 70%+.

If by "monitor" you mean automatically alert me whenever a competitor launches/changes a Google ad, capture the creative, follow the landing-page changes, and maintain a historical timeline, I can narrow this down to the 3–5 tools that actually do that well, including pricing and how close they get to real-time.

If you specifically want competitor monitoring across Google Search + Google Display, including creatives and landing pages, I’d shortlist these:

My recommendation

If you need one tool: Semrush is probably the closest fit for Search + broader advertising intelligence. It lets you inspect competitors' paid-search ads, keywords, ad copy, and associated landing pages. www.semrush.com

If Display is equally important: use Semrush + Adbeat. Adbeat is much better for seeing actual display creatives, publishers/sites where competitors appear, landing pages, and campaign changes/alerts. www.adbeat.com

If your focus is primarily Google Search: SpyFu is arguably the strongest choice. It has extensive historical Google Ads data, including ads, keywords, landing pages, and changes over time. www.spyfu.com

There's also a useful free layer: Google's Ads Transparency Center lets you search advertisers and see ads Google has served, including Search and Display. adstransparency.google.com

For your exact use case, I'd rank them:

1. 🥇 Semrush + Adbeat — best overall competitive monitoring
2. 🥈 Semrush alone — best single-tool compromise
3. 🥉 SpyFu — best for Search/PPC intelligence
4. Google Ads Transparency Center — best free source, but less useful for automated competitive monitoring

If you're looking for something that automatically alerts you when a competitor launches a new creative, changes a landing page, or starts/stops running ads, that's a narrower requirement and I'd choose differently.

If you specifically want to monitor competitor creatives + landing pages across Google Search and Google Display, I’d shortlist these:

My picks

1. Best single tool: Similarweb Ad Intelligence

Similarweb Ad Intelligence

This is probably the closest match to what you're describing. It explicitly covers search + display + video + social, and lets you analyze competitor creatives, landing pages, keywords and spend trends. Its Search Ads Analytics also exposes the landing-page destinations associated with competitor ads. www.similarweb.com

2. Best for Google Search: Semrush

Semrush Advertising Research

Semrush is particularly strong for Search. You can see competitor ad copy, keywords, historical ad activity and the landing pages receiving paid traffic. www.semrush.com

If you add AdClarity, Semrush becomes much more interesting for display intelligence; Semrush describes AdClarity as providing advanced insight into competitors' paid advertising across display, video and social. www.semrush.com

3. Best specifically for Google Display: Adbeat

Adbeat

If display is the important part, I'd seriously consider Adbeat. It specializes in competitive display intelligence and lets you see competitors' ads, publishers, ad copy and landing pages, with alerts when advertisers launch new campaigns. www.adbeat.com

What I'd use

If your requirement is:

"Give me a dashboard where I can enter 10 competitors and continuously see what they're running on Google Search and Display, what the creatives look like, where those ads send traffic, and when something changes."

I'd go Similarweb first, or Semrush + AdClarity if you want deeper PPC/search analysis.

If your priority is display creative surveillance, go Adbeat.

If your priority is Google Search competitor ads/history/keywords, go Semrush or SpyFu. SpyFu, for example, maintains historical competitor ads and associated links/landing pages. www.spyfu.com

If you tell me your budget (e.g. <$200/mo, $500/mo, $1k+/mo) and whether you need actual screenshots of the display creatives, I can narrow this to the best 2–3 options.

If you specifically want competitor monitoring across Google Search + Google Display, including creatives and landing pages, I’d shortlist these:

My pick: Similarweb

Similarweb Ad Intelligence is probably the closest match to your exact requirement. It combines search, display, creative, landing-page and spend intelligence rather than being primarily an SEO/PPC keyword tool. Similarweb says its Ad Intelligence product can analyze competitors' creatives, landing pages, keywords and spend trends across display, video, social and search. www.similarweb.comwww.similarweb.com

Its Paid Landing Page Analyzer is particularly relevant: you can identify competitors' highest-traffic paid landing pages, the ads sending traffic there, paid keywords, traffic share and estimated spend. www.similarweb.comwww.similarweb.com

Best if Search is your priority: Semrush

Semrush Advertising Toolkit is excellent for Google Search competitor monitoring. Its Advertising Research reports expose competitor ad copy, keywords, ad history and the landing pages associated with those ads. www.semrush.com

For example, its Pages report specifically identifies the landing pages receiving the most paid traffic from a competitor's Google Ads campaigns. www.semrush.com

It also has tooling for display, video and social intelligence through AdClarity, although I'd favor Similarweb or Adbeat if display creative intelligence is the main objective. www.semrush.com

Best for Display creatives: Adbeat

Adbeat is the one I'd look at if your biggest concern is "What display ads are my competitors actually running?"

It focuses heavily on display competitive intelligence and lets you investigate competitor ads, ad copy, publishers, networks and landing pages, with alerts for newly launched campaigns. www.similarweb.comwww.similarweb.comwww.semrush.comwww.adbeat.comwww.semrush.com

The important distinction

If your requirement is:

"Tell me whenever Competitor X launches/changes a Google Search or Display creative, show me the creative, where it ran, and the landing page it points to."

I'd investigate Similarweb first, then Adbeat + Semrush if you want deeper specialization.

If it's:

"I mainly need to know their Google Search keywords, ad copy, historical ads and landing pages."

I'd choose Semrush.

And if it's:

"I care primarily about banner/native/display creative, placements and advertiser behavior."

I'd choose Adbeat.

One caveat: competitor-ad intelligence is inherently observational. For Google Search, even Semrush notes that no provider captures every ad because SERPs change rapidly and targeting can be localized or audience-specific. www.semrush.com

If you tell me your industry + roughly how many competitors you want to monitor, I can narrow this down to the best 2–3 tools and compare their pricing, alerting, creative coverage, historical data, and API/export capabilities.

If you specifically want competitor monitoring across Google Search + Google Display, including creatives and landing pages, I’d shortlist these:

My recommendation: use Semrush + Adbeat

Semrush Advertising Research is probably the closest match if Google Search is the priority. It lets you see competitors' search ad copy, keywords, historical ad activity, and the landing pages associated with their ads. Its Pages report specifically identifies landing pages receiving paid traffic. www.semrush.com

Adbeat is much stronger for the Display side. It tracks competitor display ads, publishers/placements, ad networks, creative, and landing pages, and importantly supports alerts when competitors launch new campaigns. www.adbeat.com

Similarweb Ad Intelligence is the strongest alternative if you want a broader view across search + display + video + social, with competitor creatives, landing pages, spend trends, and channel allocation in one platform. www.similarweb.com

SpyFu Ad History is excellent if your main objective is Google Search ad history. It provides historical ads, the keywords triggering them, links/landing pages, and real-time tracking. www.spyfu.com

One important distinction

If by "monitor" you mean automatically tell me when a competitor changes an ad, launches a new creative, or switches landing pages, I'd lean toward Adbeat for Display and Semrush/SpyFu for Search rather than relying on a generic SEO platform.

Also, Google's own Ads Transparency Center is useful as a free supplement, particularly for seeing a competitor's Google creatives across Search, Display, YouTube and other Google properties, although it doesn't provide the same competitive historical/analytics layer. www.semrush.com

If I were building a competitor-ad monitoring stack today:
Search → Semrush or SpyFu
Display → Adbeat
Cross-channel executive view → Similarweb

If you tell me whether you're B2B SaaS, ecommerce, agency, or another category, I can narrow this down to the 2–3 tools actually worth paying for and compare their current pricing/features.

If you specifically want competitor Google Search + Google Display creatives + the landing pages those ads point to, I’d shortlist these:

My pick

Similarweb is probably the closest match to what you're describing if you want one platform. Its Ad Intelligence product covers search and display and lets you analyze competitors' creatives, landing pages, keywords, and spending trends. www.similarweb.com

For Google Search specifically, Semrush is particularly strong: it tracks competitor ad copy, keywords, historical ads, and the landing pages associated with those ads. www.semrush.com

For Google Display, I'd lean toward Adbeat. It is specifically built around display advertising intelligence and lets you see competitor creatives, publishers, ad networks, and landing pages, with alerts when advertisers launch new campaigns. www.adbeat.com

If your workflow is “tell me whenever competitor X launches a new Google ad, show me the creative, and show me the landing page,” I'd evaluate Similarweb vs. Adbeat first.

If you tell me your budget (e.g. <$200/mo, $500/mo, $1k+/mo) and whether you care more about Search or Display, I can narrow it to the best 2–3 options.

If you want one tool that covers both Google Search and Google Display competitor intelligence, I’d start with Semrush.

Best fit: Semrush

For Google Search, Semrush's Advertising Research lets you enter a competitor domain and see their paid keywords, ad copy, ad history, and the landing pages associated with their ads. www.semrush.com

For Display, Semrush's AdClarity extends this into display/video/social competitive intelligence, including competitor ads, placements, estimated spend, impressions and other campaign metrics. www.semrush.com

Semrush Advertising Research

Best specifically for Display: Adbeat

If Google Display is the main thing you care about, I'd seriously consider Adbeat instead. It specializes in display competitive intelligence and lets you inspect competitor creatives, publishers/placements, ad networks, landing pages, flight dates and trends. It also has alerts for new campaigns. www.adbeat.com

Adbeat advertiser intelligence

My recommendation:

• Need Search + Display in one stack → Semrush
• Mostly Display and want deep creative/placement intelligence → Adbeat
• Mostly Search/PPC keyword and competitor analysis → Semrush/SpyFu
• Want to monitor creative + destination-page changes over time → Semrush + Adbeat is the strongest combination

One caveat: these platforms are competitive-intelligence datasets, not direct access to Google's complete live auction data, so "monitor" shouldn't be interpreted as seeing every impression or every ad a competitor runs.

If you tell me your budget (e.g. <$200/mo, $500/mo, $1k+/mo) and whether you care more about creative screenshots, landing-page changes, spend estimates, or alerts, I can narrow it to the best 2–3 options.

If you specifically want competitor Google Search + Google Display creative + landing-page monitoring, I’d shortlist these:

My pick: Similarweb

Similarweb Ad Intelligence is probably the closest single-tool match to what you're describing. It explicitly covers competitors across search and display, including their creatives, landing pages, keywords and spend trends. Its Search Ads product also exposes the destination URLs behind competitors' ads. www.similarweb.com

If Display is the priority: Adbeat

Adbeat is stronger if you're primarily interested in Google/display-style banner and native advertising intelligence. It shows competitor creatives, publishers, ad copy and landing pages, and can alert you when competitors launch campaigns. www.adbeat.com

If Search/PPC is the priority: Semrush or SpyFu

Semrush Advertising Research is excellent for Google Search competitor research—ad copy, keywords, estimated spend, competitors and landing pages. www.semrush.com

SpyFu is particularly useful if you want historical Google ad creatives and want to see which copy competitors have repeatedly used, along with the associated landing pages. www.spyfu.com

Don't overlook Google's free option

Google Ads Transparency Center is Google's own searchable database of ads. You can search advertisers and filter by platform, including Search. It's useful for verifying what Google is actually serving, but it's much less useful as an automated competitive-monitoring system. adstransparency.google.com

If your requirement is specifically:

"Give me a list of 20 competitors, continuously watch their Google Search + Display ads, save every new creative, show me the landing page, and alert me when something changes."

I'd lean Similarweb + Adbeat rather than Semrush alone.

If you tell me your budget (e.g. <$200/mo, $1k/mo, $5k+/mo) and whether you need automated alerts/API access, I can narrow it down to the 2–3 best options.
