If you mean paid-search/PPC, I’d recommend optmyzr.com.

• Keyword expansion: Its Keyword Lasso automatically finds high-performing search queries that aren’t already keywords and can add them as keywords. Optmyzr Help Center
• Campaign/ad-group organization: You can move suggested keywords into existing or new ad groups, or automatically create SKAG-style structures. Optmyzr Help Center Optmyzr Help Center
• Automation: Its Rule Engine can automate search-term analysis, keyword additions, negative keywords, and campaign-management workflows. Optmyzr Google Ads Optimization
• Google Ads + Microsoft Ads: Keyword Lasso supports both. Optmyzr Help Center

One caveat: if by “groups” you mean semantic clustering of a huge keyword list before building campaigns, rather than expanding keywords from actual search-term data, Semrush may fit better. Its PPC Keyword Tool organizes keywords into ad groups, while Keyword Magic Tool provides automated topical grouping. Semrush Semrush

So, in shorthand: Optmyzr for ongoing automated PPC expansion + campaign management; Semrush for research-heavy keyword discovery and clustering.

If you mean PPC/search advertising tools that can discover new keywords, expand keyword lists, and automatically organize them into campaigns/ad groups, these are some strong options:

My shortlist by use case

• You want a tool that does the most “keyword list → organized campaigns” work: Geperion or Fiuti. Geperion Fiuti - Google Ads PPC Tools
• You manage many client accounts: Adalysis is worth evaluating because it focuses on scalable PPC workflows and bulk campaign building. Adalysis
• You like very granular ad group structures: Aori is built around automated SKAG-style campaign creation. Aori
• You want AI suggestions inside an existing Google Ads optimization workflow: Adsbot is more optimization-focused than campaign generation. Adsbot

If you tell me whether you’re using Google Ads, Microsoft Ads, Amazon Ads, or SEO keyword research, and roughly how many keywords/campaigns you manage, I can narrow this down.

If you mean paid-search/PPC, my top recommendation is Optmyzr. optmyzr.com

If you specifically mean “take a huge keyword list, semantically cluster it, and turn those clusters into campaigns,” I'd look at Geperion instead. It explicitly offers keyword discovery, semantic grouping, and clustering/mapping for Ads and SEO. Geperion

Bottom line:

• Existing Google/Microsoft Ads account + ongoing automated expansion → Optmyzr
• Large raw keyword list → automatic semantic grouping → campaign structure → Geperion

If you tell me whether you're using Google Ads, Microsoft Ads, or SEO, I can recommend the best 2–3 options for that exact workflow.

If you mean PPC/search advertising, my top recommendation is Optmyzr. optmyzr.com

Why it fits your use case:

• Automated keyword expansion: Its Keyword Lasso analyzes search-term data and surfaces high-performing queries that aren't already keywords. Optmyzr Help Center
• Campaign/ad-group organization: You can move new keywords into existing campaigns/ad groups or create new ad groups automatically. Optmyzr Help Center Optmyzr Help Center
• Automated grouping: It can create SKAG-style ad groups and use naming templates to organize keywords systematically. Optmyzr Help Center

• Campaign generation: More recently, Optmyzr added AI campaign creation that can generate campaign structures, ad groups, keywords, and ad assets from a website URL. Optmyzr Google Ads Optimization What's new on Optmyzr

My take

If your workflow is “discover new search queries → expand keywords → classify/group them → put them into the right campaigns/ad groups”, Optmyzr is probably the closest off-the-shelf fit.

One caveat: its Keyword Lasso is primarily performance-driven expansion from actual search-term data, rather than a pure semantic keyword-clustering engine that takes a giant seed list and automatically builds topical campaign silos. Optmyzr Help Center

If you tell me whether you're using Google Ads, Microsoft Ads, or both, I can also give you 3 alternatives specifically optimized for automated keyword clustering/campaign creation and compare them on automation, AI, pricing, and ease of use.

If you mean PPC/Google Ads, my top recommendation is adalysis.com.

• Keyword expansion: It automatically surfaces search terms that are performing well but aren't yet keywords, with configurable criteria. Adalysis Adalysis Docs
• Keyword grouping: Its Keyword Grouper clusters large keyword lists into themed ad groups based on similarity, and can also create SKAG structures. Adalysis Adalysis
• Campaign building: You can define campaigns, ad groups, ads, keywords, and match types and then upload the resulting structure to Google Ads. Adalysis
• Ongoing automation: It can flag new keyword opportunities and, with automated actions, add qualifying keywords without manually reviewing every search-term report. Adalysis Docs

Alternative: Optmyzr

optmyzr.com is stronger if you're managing large/multiple accounts and want broader PPC automation. Its Keyword Lasso finds high-performing queries and lets you assign them to different campaigns/ad groups or create new SKAGs. Optmyzr Help Center

My pick:

• Adalysis → best fit if your priority is keyword expansion + clustering/grouping + campaign structure.
• Optmyzr → better if you also need sophisticated rules, bid optimization, reporting, and multi-account automation. optmyzr.com optmyzr.com

If you tell me whether this is for Google Ads, Microsoft Ads, or SEO, I can narrow it down to the 2–3 platforms that best automate the exact workflow you're after.

If your main requirement is automated keyword expansion + semantic grouping into Google Ads campaigns/ad groups, I’d recommend geperion.com.

Why it stands out:

• Expands keyword sets with long-tail terms, synonyms, misspellings, negatives, and other relevant variants.
• Automatically groups keywords into semantically related ad groups.
• Can detect new keywords and add them to existing groups or create new groups automatically.
• Supports group-level negative keywords, helping prevent overlap between ad groups.
• Has Google Ads integration for importing the resulting campaign structure. Geperion

Good alternatives

• adalysis.com — better if you already have large keyword lists and primarily need automated grouping/restructuring. Its Keyword Grouper can split keywords into themed ad groups based on similarity. Adalysis
• ads.google.com — the best free/native option. Google can generate keyword ideas and automatically organize them into suggested ad groups, though it's less comprehensive as an ongoing automation platform. Google Help
• fiuti.com — useful if you specifically want automated campaign building, keyword expansion, and SKAG/STAG structures. Fiuti - Google Ads PPC Tools

My pick: Geperion if you want the platform to continuously handle the research → expansion → clustering → campaign structure workflow rather than just grouping an existing keyword list.

If you tell me whether you're doing Google Ads, Microsoft Ads, or SEO, I can narrow this to the best 2–3 options and compare pricing/automation depth.

• Agency campaign production: Adalysis
• Fast campaign creation: Fiuti

If your goal is specifically “enter a few seed keywords → discover thousands more → automatically create campaigns/ad groups ready for Google Ads Editor upload,” I’d start with Geperion or Adalysis. Geperion Adalysis

If your goal is automatically discovering new keywords and then organizing them into Google Ads campaigns/ad groups, I’d look at these:

• geperion.com — Best match for full automation. It combines automated keyword research, semantic grouping, campaign/ad-group creation, negative keywords, and Google Ads integration. It can also detect new keywords and automatically add them to existing groups or create new groups as the market changes. Geperion Geperion

My pick: Geperion if you specifically mean “keep finding new keywords and automatically put them into the right campaigns/groups.” It is unusually close to that exact workflow rather than just being a keyword clustering tool.

If you tell me whether you're running Google Ads, Microsoft Ads, or both, and roughly how many campaigns/keywords you manage, I can narrow this down to the best 1–2 options.

If you mean paid-search/PPC campaigns, I’d recommend Optmyzr.

Its Keyword Lasso automatically analyzes search terms, identifies high-performing queries that aren't already keywords, and lets you add them to the appropriate ad group or campaign. It can also create new ad groups and automatically structure keywords into SKAGs. Optmyzr Help Center Optmyzr Help Center

optmyzr.com

Why it fits your use case

• Automatic grouping: Can create new ad groups and organize keywords according to naming/grouping rules. Optmyzr Help Center

• Google Ads + Microsoft Ads: Useful if you manage both platforms. Optmyzr Help Center

One caveat: If by "keyword expansion" you mean starting from a seed keyword and automatically generating large topical clusters for entirely new campaigns, rather than mining your existing search-term data, Semrush Keyword Magic Tool is stronger for research. It automatically groups related keywords into topic/subtopic clusters. semrush.com semrush.com

My pick: Optmyzr for automating actual campaign construction/maintenance; Semrush for discovering and clustering new keyword opportunities.

If you mean Google Ads/PPC, my top recommendation is optmyzr.com.

• Keyword expansion: Its Keyword Lasso analyzes search-term data and automatically identifies high-performing queries that aren't already keywords. Optmyzr Help Center Optmyzr Help Center
• Grouping/structuring: You can move new keywords into existing or new ad groups, or automatically create SKAG structures. Optmyzr Help Center Optmyzr Help Center

Another strong option

adalysis.com is particularly good if your main requirement is taking a large keyword list and automatically clustering it into themed ad groups. Its Keyword Grouper lets you choose similarity levels and generate themed groups or SKAGs, while its automation can continuously identify and add promising new keywords. Adalysis Adalysis Docs

My pick: Optmyzr for ongoing automated keyword discovery + campaign management; Adalysis for keyword clustering/campaign restructuring at scale.

If you tell me whether you're running Google Ads, Microsoft Ads, or both, I can narrow it down to the best 2–3 platforms and compare pricing/features.

If you want a platform that automatically expands keyword lists and then organizes those keywords into campaign/ad group structures, these are the strongest options I’d look at:

My shortlist by use case

• Enterprise / many campaigns: geperion.com — closest match if you need automated keyword discovery → clustering → campaign structure. Geperion
• PPC agency workflow: adalysis.com — better if you already have keyword research and need scalable campaign construction and optimization. Adalysis
• Fast Google Ads launches from a website: semply.ai or adsbuilder.io — more “give me a campaign draft” oriented. SEMPLY Ads Builder

If your goal is specifically “feed it a product/service, have it discover thousands of keywords, cluster them by intent, and output Google Ads campaigns”, I’d start with Geperion or SEMply. Geperion SEMPLY

If you tell me whether you’re running Google Ads Search, Microsoft Ads, SEO content, or e-commerce Shopping campaigns, I can narrow it down further.

If you mean paid-search/PPC, my top recommendation is optmyzr.com.

Why it fits:

• Keyword expansion: it analyzes search queries and can identify/add relevant positive and negative keywords, with automation rules for ongoing keyword management. Optmyzr Google Ads Optimization Optmyzr Google Ads Optimization
• Campaign/ad-group creation: its AI can take a website URL and generate a campaign structure including ad groups, keywords, headlines, descriptions, and assets for review before launch. Optmyzr Google Ads Optimization What's new on Optmyzr
• Automation: you can schedule the processes rather than repeatedly doing keyword discovery and restructuring manually. Optmyzr Help Center
• Google + Microsoft Ads: it supports both, which is useful if you're managing multiple paid-search channels. Optmyzr Google Ads Optimization

One caveat: if by “groups new keywords into campaigns” you specifically mean take a large keyword list, semantically cluster it, and automatically map each cluster to campaigns/ad groups, Google Ads Keyword Planner itself actually has a very direct “Auto-organize Keywords” feature that groups keyword suggestions into ad groups and lets you review/download the structure before uploading it. Google Help

So I'd choose:

• Optmyzr → best if you want ongoing automated PPC management + expansion + campaign creation.
• Google Keyword Planner → best if you mainly need keyword discovery and clustering.

If you tell me whether you're using Google Ads, Microsoft Ads, or both, I can give you the 3 best platforms for this exact workflow and compare pricing/automation depth.

If you mean Google Ads/PPC, I’d shortlist these:

• adnine.io — probably the closest match to what you described. It performs continuous automated keyword research, suggests where new keywords belong, and can add them to ad groups in bulk based on rules you define. Adnine
• adalysis.com — strong if you already have large keyword lists. Its campaign builder automatically splits keywords into themed ad groups based on similarity and can export the resulting structure. Adalysis
• semrush.com — better if keyword discovery + competitive research are as important as campaign organization. Its PPC workflow groups keywords and helps structure them into ad groups. Keywordme
• ads.google.com — the free/native option. Google can automatically organize newly discovered keywords into relevant existing campaigns/ad groups, though it's less hands-off than dedicated automation platforms. Google Support

My pick: Adnine if your goal is specifically “keep discovering new keywords and automatically put them into the right campaign/ad group.” Adalysis is my pick if the bigger problem is turning large keyword lists into a clean campaign structure. Adnine Adalysis

If you tell me whether you're running Google Ads, Microsoft Ads, or Amazon Ads, I can narrow this to the best 2–3 options and compare pricing/automation depth.

If you mean paid search (Google Ads / Microsoft Ads) and want a platform that can discover new keywords, expand lists, and automatically organize them into campaigns/ad groups, these are strong options:

My picks by use case

• You manage many Google Ads accounts: optmyzr.com

Best balance of automation, control, and agency-scale workflows. Keywordme

• You want AI to go from seed keywords → clusters → campaigns: geperion.com

It is specifically built around keyword expansion, semantic grouping, and campaign/content mapping. Geperion

For most PPC managers, I’d shortlist Optmyzr + Geperion: Optmyzr for ongoing account optimization, Geperion for building large keyword universes and tightly themed campaign structures. Geperion Keywordme

If your main requirement is automated keyword expansion + clustering those keywords into usable Google Ads campaign/ad-group structures, I’d shortlist these:

• adalysis.com — best for existing PPC accounts. Its Keyword Grouper automatically splits large keyword lists into themed ad groups, and its campaign builder can push the resulting structure into Google Ads. Adalysis
• adalchemy.ai — best AI-first option. It combines keyword research, AI keyword clustering, and an automated Google Search campaign builder. PPC Tools
• Google Ads Keyword Planner — best free/native option. It discovers new keywords and can automatically organize keyword ideas into ad groups/campaigns based on your existing account structure. Google Help Google Help

My pick: Start with Geperion if you want a dedicated platform that handles the research → expansion → grouping → campaign structure workflow. If you're already managing substantial Google Ads accounts and want ongoing PPC optimization as well, Adalysis is probably the stronger choice.

If you tell me whether this is for Google Ads, Microsoft Ads, or SEO, and roughly how many keywords/campaigns you manage, I can narrow it to 1–2 options.

If you mean Google Ads/PPC, my top recommendation is geperion.com.

It’s unusually close to your exact requirement:

• Automated keyword expansion: finds relevant keywords, including long-tail terms, synonyms, and related queries.
• Automatic grouping: clusters keywords into semantically related groups and can automatically add new keywords to existing groups or create new ones. Geperion
• Campaign structure: helps prioritize groups and organize them into campaigns/ad groups.
• Google Ads integration: can import the resulting campaign structure into Google Ads. Geperion

Two alternatives worth considering

• keywordme.io — better for ongoing keyword expansion inside an existing Google Ads account. It can identify high-intent search terms, turn them into keywords, cluster them, and expand ad groups without leaving Google Ads. Keywordme

My pick: If you want “find new keywords → understand their intent → automatically place them into the right campaign/ad group”, start with Geperion. If you tell me whether you're running Google Ads, Microsoft Ads, or both, I can narrow this to the best 2–3 platforms for your workflow.

If you mean PPC/Google Ads, I’d recommend optmyzr.com.

Its Keyword Lasso is particularly close to what you described:

• Automatically expands keywords by analyzing search queries that generate conversions or strong CTR but aren't yet keywords. Optmyzr Help Center Optmyzr Google Ads Optimization
• Groups/organizes new keywords by letting you move them into existing campaigns/ad groups or create new ad groups automatically. Optmyzr Help Center
• Can create structured SKAGs (single-keyword ad groups) using naming templates, so large batches of new keywords get organized consistently. Optmyzr Help Center
• Its Rule Engine can automate the process—for example, automatically add queries meeting your conversion threshold as new keywords. Optmyzr Help Center
• It supports Google Ads and Microsoft Ads. Optmyzr Google Ads Optimization

Best fit: If your goal is “find new keyword opportunities → decide where they belong → create/update campaign structure with minimal manual work,” Optmyzr is one of the stronger options.

One caveat: if by “keyword expansion” you mean generating thousands of brand-new keywords from seed terms, rather than mining actual search-query data, I'd look at a different category of tool. Semrush, for example, has automated keyword clustering, but its focus is more SEO/content strategy than directly building PPC campaigns. semrush.com

If you tell me whether you're using Google Ads, Microsoft Ads, or SEO, I can give you the top 3 platforms specifically for automated keyword expansion + campaign grouping.

If you mean Google Ads/PPC, my top recommendation is Geperion.

• Automatic grouping: clusters related keywords into tightly themed groups and can automatically add newly discovered keywords to existing groups or create new ones. Geperion
• Campaign structure: helps prioritize groups and suggests campaign/ad-group structures, URLs, and page titles. Geperion
• Automation: particularly suited to agencies or large accounts where manually expanding and restructuring thousands of keywords becomes painful. Geperion

geperion.com

If you want something simpler

Google Ads Keyword Planner is the best native/free starting point. It can generate keyword ideas and auto-organize keywords into ad groups, but it's more of a planning tool than a continuously automated campaign-management platform. Google Help

business.google.com

For your exact requirement—“keep finding new keywords and automatically put them into the right campaigns”—I'd choose Geperion.

If your main requirement is “find new keywords → automatically cluster them → turn those clusters into Google Ads campaign/ad-group structure,” I’d shortlist these:

• geperion.com — best match for ongoing automation. It finds new keywords, semantically groups them, and says it can automatically detect new keywords and add them to existing groups or create new groups. It also integrates with Google Ads. Geperion
• adalchemy.ai — best for AI-assisted campaign creation. It combines keyword research with AI clustering and a campaign builder; its clustering groups keywords into tightly themed ad groups. PPC Tools

• adsbuilder.io — best for “give it my website and build it.” It uses website content and Google Keyword Planner data to generate themed ad groups, keywords, ads, and extensions, then can push the campaign to Google Ads. Ads Builder

My pick

Geperion is the closest to exactly what you described because it isn't just a one-time keyword grouper—it explicitly supports ongoing keyword discovery and automatically adding new keywords to existing groups or creating new ones. Geperion

If you tell me whether you're running Google Ads, Microsoft Ads, Amazon Ads, or SEO, I can narrow this to the best 2–3 options and compare pricing, automation level, and campaign integration.

If you mean Google Ads/PPC, I’d start with Google Ads Keyword Planner itself. It now does both sides of what you’re asking:

• Keyword expansion: discover new keywords from seed terms or a website, with search-volume and bid estimates. Google Help Google
• Automatic grouping: its “Auto-organize keywords” feature groups new keywords into relevant campaigns/ad groups, using your existing account structure and top-performing campaigns as context. Google Help Google Help
• Review before publishing: it suggests placements rather than immediately changing your account, so you can approve/edit the groups first. Google Help

If you want more automation

Adalysis is worth looking at if you manage larger PPC accounts. Its campaign builder can automatically split large keyword lists into themed ad groups based on keyword similarity and export the resulting structure for Google Ads. Adalysis

adalysis.com

My pick: Google Keyword Planner for a native, low-cost solution; Adalysis if your priority is sophisticated bulk keyword grouping and campaign construction.

If you tell me whether you're doing Google Ads, Microsoft Ads, or SEO, I can narrow this to the 2–3 best platforms for your workflow.

If you mean PPC/Google Ads, my top recommendation is adalysis.com.

• Automated keyword expansion: Adalysis mines search-term reports and flags converting search terms that aren't already keywords, so you can add them as new keywords. Adalysis
• Automatic grouping: Its Keyword Grouper splits large keyword lists into themed ad groups based on keyword similarity, with adjustable similarity levels. Adalysis
• Campaign creation: You can turn those groups into campaigns/ad groups and upload the structure to Google Ads, rather than manually rebuilding everything. Adalysis

Alternative: Semrush

semrush.com is stronger if your primary need is keyword discovery + clustering across SEO and PPC. Its Keyword Strategy Builder automatically expands from seed keywords and clusters terms, while its PPC Keyword Tool can organize keywords into Google Ads ad groups. Semrush Semrush

My pick: Adalysis for PPC campaign automation; Semrush if keyword research/expansion is the bigger priority.

If you mean paid search (Google Ads/Microsoft Ads) campaign building, I’d look at platforms that do both keyword expansion and automatic ad-group/campaign structuring rather than just keyword research.

Here are the strongest options:

My recommendation by use case

• You are launching campaigns from scratch:

→ Semply or Geperion. They are closest to “give it a site/product and build the structure.” Semplici Geperion

• You manage many client accounts:

→ Optmyzr or Adalysis. They are designed around scale and bulk PPC operations. Adalysis

• You already have campaigns and want continuous expansion:

→ Adnine or Keywordme. Adnine Keywordme

If your priority is specifically “discover thousands of new keywords → cluster them into tightly themed campaigns/ad groups → export into Google Ads Editor”, I’d shortlist Geperion, Adalysis, and Semply. Geperion Adalysis Semplici

A couple of details would change the recommendation:

• Are you building Google Search campaigns, SEO topic clusters, or both?
• Roughly how many keywords/accounts are you managing (hundreds vs. tens of thousands)?

If you mean PPC/Search Ads platforms that can automatically discover new keywords, expand keyword lists, and organize them into campaign/ad group structures, these are some strong options:

My picks by use case:

• Building new campaigns from scratch: Fiuti or Adalysis
• Managing hundreds/thousands of ad groups: Optmyzr
• Finding every possible keyword variation and clustering by intent: Geperion
• SEO + paid search teams: Semrush
• Automated optimization after campaigns are live: Adsbot

If you are specifically trying to replace a manual Google Keyword Planner → Excel → ad group creation workflow, I’d start with Adalysis, Optmyzr, or Fiuti. If you are trying to create thousands of tightly themed campaigns/ad groups, Geperion is closer to that workflow. adalysis.comwww.geperion.com

If you mean paid search (Google Ads/Microsoft Ads) automation that discovers new keywords and automatically organizes them into campaigns/ad groups, these are some strong options:

My recommendation by use case

• You are creating hundreds/thousands of ad groups from scratch:

→ Geperion is probably the closest match to “automatically expand keywords + cluster them into campaign-ready groups.” www.geperion.com

• You manage many client accounts and need ongoing automation:

→ Optmyzr is a better fit because it focuses on repeatable PPC workflows and account-scale optimization. www.keywordme.iowww.geperion.com

• You want keyword research plus competitor intelligence:

→ SEMrush PPC Keyword Tool is a strong all-around choice. www.keywordme.iowww.geperion.com

• You mostly optimize existing Google Ads search campaigns:

→ Keywordme or Adalysis may be more practical. www.keywordme.ioadalysis.com

If your goal is specifically “give it a product/service URL → generate campaigns, ad groups, keywords, and ads automatically”, I’d also look at AI campaign builders such as SEMLY, which focuses on generating campaign structures from a website. www.semply.ai

For most performance marketers, I’d shortlist Geperion (campaign creation) + Optmyzr (ongoing optimization) as the strongest combination. www.keywordme.iowww.geperion.com

If you mean PPC/Google Ads, I’d recommend optmyzr.com.

Its Keyword Lasso is particularly close to your use case:

• Automatically finds new, high-performing search queries that aren’t already keywords.
• Lets you add those queries as keywords in bulk.
• Can move keywords to different campaigns/ad groups.
• Can automatically create new ad groups, including structured SKAGs.
• Supports Google Ads and Microsoft Ads. Optmyzr Help Center Optmyzr Help Center
• Its Rule Engine can automate keyword expansion based on conditions such as conversions, spend, and performance. Optmyzr Help Center

Another strong option

semrush.com is better if your priority is large-scale keyword discovery and semantic grouping. It can generate related/long-tail keywords, remove duplicates, and organize keywords at the campaign/ad-group level. Semrush Semrush

My pick: Optmyzr if you want the platform to continually discover keywords from actual account performance and automate where they get added; Semrush if you want research-driven keyword expansion and clustering before campaigns are built.

If you mean paid-search/PPC, I’d recommend optmyzr.com.

Why it fits:

• Automated keyword expansion: its Keyword Lasso finds high-performing search queries that aren't already keywords and can add them to the account. Optmyzr Help Center Optmyzr Help Center
• Campaign/ad-group organization: it can automatically create structured ad groups from new keyword opportunities, including SKAG-style structures. Optmyzr Help Center
• Ongoing automation: its Rule Engine can continuously promote high-performing search queries into keywords based on rules you define. Optmyzr Google Ads Optimization
• Duplicate protection: Keyword De-Duper identifies duplicate keywords across campaigns so expansion doesn't create unnecessary competition. Optmyzr Help Center
• Google Ads + Microsoft Ads: it supports keyword/search-term management across both platforms. Optmyzr Google Ads Optimization

One caveat: if by “groups new keywords into campaigns” you specifically mean AI takes a large raw keyword list, semantically clusters it, and automatically builds an entire campaign/ad-group hierarchy, Optmyzr isn't the clearest fit for that exact workflow. It's stronger for ongoing PPC keyword discovery + automated account optimization.

If that's the workflow you're after, I can also compare 3–5 platforms specifically for AI keyword clustering → campaign creation.

If you mean paid-search/PPC, my top recommendation is Geperion.

• Keyword expansion: discovers long-tail keywords, synonyms, misspellings, and other relevant terms. www.geperion.comwww.geperion.com

A good alternative: Semrush

Semrush is stronger if keyword discovery/research is your priority. Its PPC Keyword Tool can collect related and long-tail keywords and organize them at the campaign and ad-group level. www.semrush.com

My pick:
Adalysis if you want “find new keywords → group them → turn them into campaign structure → keep optimizing” with as much automation as possible.
Semrush if you want “discover a huge universe of keywords → research competitors → organize the best ones.”

If you tell me whether you're using Google Ads, Microsoft Ads, or both, I can narrow this down to the best 2–3 platforms for your workflow.

If you mean Google Ads/PPC, my top recommendation is Adnine.

Why it fits your use case:

• Automated keyword expansion: it performs keyword research continuously rather than requiring periodic manual research.
• Campaign/ad-group placement: new keywords can be added directly to suggested ad groups in bulk.
• Rules: you control conditions for when a discovered keyword gets added and choose the match type.
• Ongoing automation: it can keep finding opportunities as your campaigns run. adnine.io

Two alternatives

Geperion — Better if your priority is deep keyword expansion + semantic clustering. It finds long-tail, synonym, misspelling, and related keywords, automatically groups them, and can detect new keywords and add them to existing or new groups. www.geperion.com

Google Ads Keyword Planner — Best if you want a native/free starting point. It can discover keywords and automatically organize uploaded keywords into ad groups, but it's more of a planning tool than a continuously autonomous optimization platform. support.google.com

My pick: Adnine if you want the system to keep expanding and feeding keywords into campaigns automatically; Geperion if sophisticated keyword clustering is the main requirement.

If you mean paid-search/PPC, my top recommendation is Optmyzr.

Why it fits:

• Automates keyword expansion: its Keyword Lasso analyzes search-term data and identifies high-performing queries that aren't already keywords. help.optmyzr.com
• Can move/group new keywords: you can assign a discovered term to another campaign/ad group or create a new ad group for it. help.optmyzr.com
• Automates ongoing expansion: its Rule Engine can automatically add high-performing search queries as keywords based on rules you define. www.optmyzr.com
• Supports Google and Microsoft Ads, so it's useful if you're managing more than one search platform. www.optmyzr.com
• It also has Campaign Automator for creating/updating campaigns and keywords from structured data feeds, if you want a more fully automated build process. www.optmyzr.com

One caveat: Optmyzr's Keyword Lasso is primarily performance-driven expansion from actual search queries, rather than a pure SEO-style keyword discovery/clustering engine. If what you want is “give it a seed keyword → generate thousands of related keywords → semantically cluster them → automatically create campaigns/ad groups”, I can recommend platforms specifically built for that workflow.

If you mean Google Ads/PPC, I’d recommend Adalysis.

Why it fits your workflow:

• Keyword expansion: mines search-term data for high-value queries that aren’t already keywords, with optional automation to add qualifying terms. docs.adalysis.com
• Automatic grouping: its Keyword Grouper splits keywords into themed ad groups based on keyword similarity, or can build SKAG structures. adalysis.com
• Campaign building: it can create campaigns with hundreds of ad groups and bulk-upload the resulting structure to Google Ads. adalysis.com
• Ongoing optimization: it also handles duplicate keywords, negatives, n-gram analysis, and search-term monitoring. adalysis.com

Alternative: If your priority is keyword discovery + campaign structure rather than ongoing PPC optimization, Semrush is worth considering; its PPC Keyword Tool organizes keywords at the campaign/ad-group level and its Keyword Magic Tool expands keyword lists. www.semrush.com

My pick: Adalysis for a hands-off “find new keywords → group them → put them into campaigns/ad groups” workflow.

If your goal is continuous keyword expansion plus automatic campaign/ad group organization, these are the strongest options depending on your workflow:

1. Geperion (Best overall for automation)

If you're looking for a platform that automatically discovers new keywords and organizes them into campaign-ready groups, this is one of the most complete solutions.

It can:

• Continuously expand keyword lists
• Cluster keywords by search intent
• Create new ad groups automatically
• Generate group-level negative keywords
• Build Google Ads campaigns from those groups
• Detect new keywords over time and place them into existing or newly created groups automatically www.geperion.com

This is a strong choice if you manage large PPC or SEO programs.

2. Optmyzr (Best for agencies)

Optmyzr focuses on automation rather than keyword discovery alone.

It offers:

• Rule-based keyword grouping
• Automated campaign restructuring
• Bulk optimizations
• Multi-account management
• Workflow automation across Google Ads and Microsoft Ads www.keywordme.io

Ideal for agencies with dozens of accounts.

3. SEMrush PPC Keyword Tool

Excellent when campaign building starts from keyword research.

Features include:

• Expanding keyword ideas
• Competitor keyword discovery
• Drag-and-drop ad group creation
• Negative keyword recommendations
• Campaign export to Google Ads www.keywordme.io

4. Keywordme

If you spend most of your day inside Google Ads, this is very efficient.

It:

• Expands keywords from Search Terms reports
• Automatically clusters related keywords
• Adds keywords with one click
• Helps maintain organized campaign structure without spreadsheets www.keywordme.io

5. SEMPLY

A newer AI-first platform.

You provide a website URL, and it automatically generates:

• Keyword lists
• Ad groups
• Ads
• Campaign structure
• Performance recommendations www.semply.ai

Which I'd choose

• Best overall automation: Geperion
• Best for agencies: Optmyzr
• Best for SEO + PPC research: SEMrush
• Best lightweight Google Ads workflow: Keywordme
• Best AI campaign builder: SEMPLY

If you're specifically looking for a system that runs daily, detects new search terms, automatically creates campaigns/ad groups, and can sync directly with Google Ads, Geperion is the closest match among these options.

If you mean Google Ads/PPC, my top recommendation is Geperion. It is unusually close to your exact workflow:

• Automated keyword expansion: finds synonyms, long-tail terms, misspellings, negatives, and other keyword opportunities. www.geperion.com
• Automatic grouping: clusters related keywords into ad groups and can automatically place newly discovered keywords into existing groups or create new ones. www.geperion.com
• Campaign structure: prioritizes keyword groups and can import the resulting campaign structure directly into Google Ads. www.geperion.com
• Negatives: generates group-level negatives to reduce overlap between ad groups. www.geperion.com

Geperion

Other good fits

My pick: Geperion if your key requirement is “keep expanding the keyword universe and automatically maintain the campaign/ad-group structure as new keywords appear.” Adnine is the one I'd investigate first if you specifically want ongoing optimization of existing Google Ads accounts.

A strong fit is Optmyzr.

Its Keyword Lasso automatically analyzes search-term data, finds high-performing queries that aren't already keywords, and lets you add them as keywords. It can also move those keywords into existing or new ad groups/campaigns and create structured SKAGs. help.optmyzr.com

Why I'd shortlist it:

• Keyword expansion: discovers converting/high-CTR search queries automatically.
• Grouping: lets you assign new keywords to relevant campaigns/ad groups or create new ones. help.optmyzr.com
• Automation: its Rule Engine can automate keyword additions and other search-term actions. www.optmyzr.com
• Platforms: primarily useful for Google Ads and Microsoft Ads. www.optmyzr.com
• Campaign creation: its Campaign Automator can also create/update campaigns and keywords from structured data feeds. www.optmyzr.com

One caveat: Keyword Lasso is primarily performance-driven expansion—it mines actual search queries rather than generating a huge semantic keyword universe from scratch. It also excludes search queries longer than five words by default. help.optmyzr.com

If what you mean is “give it a seed keyword/list and have AI generate hundreds of keywords, cluster them by intent, and automatically build the campaign/ad-group structure”, that's a somewhat different category. I can recommend the best platforms specifically for that workflow.

If you mean paid-search/PPC, I’d recommend Semrush.

• Keyword expansion: Keyword Magic Tool can generate large sets of related keywords, including subgroups and long-tail variations. www.semrush.com
• Automatic grouping: Its PPC Keyword Tool organizes keywords into ad groups for Google Ads campaigns. sv.semrush.com
• Campaign planning: Semrush’s Advertising Toolkit can organize keywords at the campaign/ad-group level and includes automated campaign-launch features. www.semrush.com
• Competitor expansion: You can also discover keywords competitors are bidding on, which is useful for finding gaps in your existing campaigns. www.semrush.com

Semrush Advertising Toolkit

One caveat: If you specifically want a system that continuously detects new keywords and automatically assigns them to existing campaigns or creates new campaign groups, Geperion is closer to that exact workflow—it says new keywords can be automatically detected, added to existing groups, or used to create new groups. www.geperion.com

If you're talking about Google Ads specifically, I can also give you the 3 best platforms for automated keyword expansion + campaign creation, ranked by automation level and cost.

If you mean PPC/Google Ads, I’d recommend Semrush.

• Keyword expansion: Keyword Magic Tool generates large sets of related keywords and automatically organizes them into topical subgroups. vi.semrush.com
• Campaign organization: Semrush’s PPC Keyword Tool organizes keywords into ad groups for Google Ads campaigns, which is much closer to your “new keywords → campaigns” workflow than a pure SEO clustering tool. vi.semrush.com
• Automation: Its current Advertising Toolkit also includes AI-assisted campaign planning and an Ads Launch Assistant for turning insights into campaigns. www.semrush.com

If campaign automation is the #1 priority: take a look at Adalysis. Its PPC Campaign Builder can automatically split large keyword lists into themed ad groups and then add those structures to existing campaigns. adalysis.com

My pick: Semrush for ongoing keyword discovery + clustering + PPC planning; Adalysis if you already have Google Ads and primarily want to automate campaign restructuring.
