Positive mentions of Moz

If your goal is prospect research before outreach, I’d focus less on raw backlink counts and more on whether a prospect has valuable, relevant, and realistically replicable links.

Top tools

Ahrefs is particularly useful when you're trying to identify which specific pages and domains are worth pursuing: its reports expose referring domains, backlinks, link attributes, URL/domain metrics, and estimated organic traffic. Ahrefs Ahrefs Help Center

Semrush is especially useful for competitive prospecting. Its Backlink Gap functionality identifies domains linking to competitors but not to you, while its backlink reports provide authority, anchor-text, link-status, and referring-domain data. Semrush Semrush

Majestic is a useful second opinion when topical relevance and link quality matter. Its Trust Flow measures backlink quality, Citation Flow measures link quantity, and Topical Trust Flow provides topical-category information; its Link Context can help distinguish editorial-style opportunities from less useful link placements. Majestic Majestic

How I'd prioritize prospects

For each prospect, build a simple sheet with:

• Relevant referring domains — are authoritative sites in your niche already linking to them?
• Organic traffic to linking domains/pages — a link from a site that actually attracts relevant visitors is generally more interesting than a high-metric site with little visibility.
• Link placement — editorial/contentual links deserve more attention than sitewide, footer, directory, or profile links.
• Topical relevance — a moderately authoritative site closely aligned with your subject can be more useful for outreach research than an unrelated high-authority domain.
• Link velocity — sudden bursts of hundreds of links warrant closer inspection rather than automatically being treated as valuable.
• Anchor/context — examine why the site linked and what the surrounding content says.
• Competitor overlap — if the same domain links to several relevant competitors, that's a strong prospecting signal because it demonstrates that the site already links within your market.
• Linkability — identify the asset/page that earned the link. That tells you what kind of content or pitch might actually work.

A particularly effective workflow is:

Semrush/Ahrefs → find competitor referring domains → filter for relevance + organic traffic → inspect the actual linking page → check whether they link to multiple competitors → research the editor/site → personalize outreach.

Don't treat DR, Authority Score, Trust Flow, or similar proprietary scores as interchangeable or as a standalone measure of link value. They're useful filtering signals, but relevance + real audience + editorial context + demonstrated willingness to link are much more informative for outreach prioritization. Majestic itself distinguishes link quality from link quantity through Trust Flow vs. Citation Flow, for example. Majestic

If you only want one tool: Ahrefs is a strong choice for this particular workflow. If you're doing serious prospecting at scale: pairing Ahrefs or Semrush with Majestic gives you a useful second perspective on link quality and topicality.

If the goal is prospect prioritization before outreach, I’d focus less on “who has the most backlinks?” and more on which linking domains are authoritative, relevant, reachable, and likely to produce a valuable link.

Top tools

1. Ahrefs — my first choice

ahrefs.com

For prospecting, Link Intersect is particularly useful: it identifies domains/pages linking to competitors but not you, and lets you filter opportunities by metrics such as DR and traffic. Ahrefs Help Center Ahrefs Help Center

I would pull:

• Referring domain
• DR
• Organic traffic
• Linking-page traffic
• Number of competitors receiving links
• Follow/nofollow status
• Anchor text
• Target page
• Link placement/context
• First-seen date

Ahrefs also exposes competitors' most-linked pages and broken pages, which can generate particularly good outreach angles. Ahrefs

Best use: Build your initial 100–500 prospect universe.

2. Semrush — excellent for competitive prioritization

semrush.com

Semrush's Backlink Gap is very similar to the workflow I'd recommend: identify authoritative domains linking to competitors but not your prospect, then sort/filter by authority and relevance. Semrush

It's especially attractive if you're already using Semrush for:

• Organic competitors
• Keyword research
• Traffic estimates
• Content gaps
• SERP analysis

Best use: When backlink prospecting needs to sit inside a broader SEO workflow.

3. Majestic — useful when link quality is the main question

Majestic is worth adding when you want a more link-graph-centric view, particularly its Trust Flow / Citation Flow and topical classifications.

I wouldn't necessarily use it as the only prospecting database, but it can be a useful second opinion on whether a seemingly powerful domain actually has a strong, relevant link profile.

Best use: Validating questionable high-authority prospects.

4. Moz Link Explorer — good lightweight qualification

Moz is useful if you want a simpler interface and familiar Domain Authority (DA) / Page Authority (PA) metrics.

I wouldn't rank prospects solely by DA, though. A DA 70 general-interest site with little topical relevance can be less valuable than a DA 45 publication that is highly authoritative within your niche.

Best use: Quick qualification and reporting.

5. Google Search Console — use it as the ground truth for your own site

GSC isn't a prospect-discovery replacement for Ahrefs/Semrush, but it's valuable for validating the backlink picture from Google's own data.

Use it alongside a commercial index rather than instead of one.

How I'd actually score prospects

For outreach, I'd build a Prospect Score rather than simply sorting by DR/DA:

Prospect Score = Authority × Relevance × Traffic × Link Opportunity × Outreach Fit

For example:

The competitor overlap signal is particularly powerful. If one publication independently links to three of your competitors, that's much more interesting than a high-DR site that has never linked to anything in your category.

Ahrefs' Link Intersect explicitly supports this kind of analysis. Ahrefs

The biggest mistake to avoid

Don't prioritize prospects by backlink count.

A site with 100,000 backlinks may have only 500 meaningful referring domains, whereas another site with 2,000 backlinks could have hundreds of genuinely relevant publishers. Referring domains are therefore much more useful for prospect qualification than raw backlink totals. Ahrefs Help Center

I'd also look for link velocity, anchor patterns, traffic, topical relevance, and outbound-link behavior. For example, dozens of apparently authoritative sites sharing suspiciously similar ownership/network signals should lower the prospect's score. Ahrefs even provides referring-IP analysis for investigating potential common networks. Ahrefs Help Center

My practical stack

If I were doing this for a serious outreach campaign:

Ahrefs → Semrush → spreadsheet/CRM → outreach platform

Use Ahrefs to discover and investigate prospects, Semrush to cross-check competitive gaps, then score prospects on relevance + authority + traffic + competitor overlap + realistic outreach opportunity.

That will generally produce a much better outreach list than simply exporting every domain above DR 50.

If you’re prioritizing link prospects by estimated traffic value + authority proxies, I’d look at these:

• Semrush — particularly useful because its Authority Score combines backlink strength, estimated organic traffic, and spam/manipulation signals. Its backlink reports also expose estimated traffic and referring-domain data. Semrush Semrush
• Ahrefs — strong for prospect discovery and backlink analysis. Domain Rating (DR) is its domain-level backlink-strength proxy, while URL Rating (UR) evaluates the specific linking page. That page-level distinction is valuable when deciding whether an individual prospect is worth pursuing. Ahrefs Help Center Ahrefs Help Center
• Moz Link Explorer — useful if you specifically want Domain Authority (DA) and Page Authority (PA). It also provides linking-domain, backlink, and ranking-keyword data. Cloudfront
• Semrush + Ahrefs together — probably the most useful combination if you're building a serious prospect database. Use Semrush for its traffic/authority/spam signals and Ahrefs for DR/UR, referring domains, and link-level analysis.

A practical prioritization model

Rather than sorting prospects solely by DA/DR, I'd create a composite score such as:

Priority = Traffic Value × Relevance × Authority × Link Opportunity Quality

For each prospect, collect:

One important caveat: DA, DR, and Authority Score aren't Google metrics. They're third-party proxies calculated differently, so a DR 60 isn't directly equivalent to DA 60 or Authority Score 60. Semrush

For actual link prospect prioritization, I'd generally put more weight on the specific linking page's relevance, authority, and traffic than on the site's homepage/domain score alone. Ahrefs explicitly distinguishes page-level UR from domain-level DR, and notes that the number of outgoing links on the referring page can also matter. Ahrefs Help Center Ahrefs Help Center

If you tell me whether you're doing digital PR, guest posts, resource-page outreach, or competitor backlink replication, I can give you a concrete scoring formula and spreadsheet columns for ranking hundreds of prospects.

For prioritizing link prospects by estimated traffic value + authority proxies, I’d look at these:

• Ahrefs — strong for link prospecting. It gives Domain Rating (DR), referring domains, and estimated organic traffic for both the referring domain and linking page, which makes it particularly useful for ranking prospects. Ahrefs
• Semrush — useful if you want Authority Score + organic traffic + backlink metrics in one workflow. Its Backlinks Overview includes referring domains, monthly visits, organic traffic, outbound domains, and toxicity signals. Semrush Semrush
• Moz Link Explorer — best if your existing prospecting/reporting process uses Domain Authority (DA). DA is a proprietary 1–100 prediction of ranking strength, so treat it as a comparative proxy rather than a Google metric. Semrush
• Majestic — useful as a supplementary link-quality signal through Trust Flow and Citation Flow, particularly when you want to examine the underlying backlink profile rather than traffic alone. Backly
• Similarweb — particularly useful for estimating overall website traffic and traffic sources. It can also identify domains referring traffic to competitors, which adds a useful "actual audience" dimension to link prospecting. Similarweb

A practical prioritization model

Rather than sorting solely by DA/DR, I'd create a prospect score roughly like:

Priority = Traffic Value + Authority + Relevance + Link Opportunity − Risk

For example:

The specific page's traffic is especially valuable: a DR 70 site isn't necessarily a better prospect than a DR 45 site if the latter has a highly relevant page receiving substantial search traffic. Ahrefs explicitly exposes estimated organic traffic for linking pages and referring domains. Ahrefs

Also, don't treat DA, DR, or Authority Score as interchangeable—they're proprietary proxies calculated from different datasets and methodologies. Semrush

If I were building a prospecting spreadsheet, I'd probably use Ahrefs as the primary dataset, Similarweb for traffic validation, and optionally Moz/Majestic as secondary authority-quality checks.

Yes. For international link building, I’d separate the stack into multilingual prospecting/research and multilingual outreach/execution:

• ahrefs.com — Strong for finding international prospects through competitor backlinks, Link Intersect/Backlink Gap, Content Explorer, and country/language-oriented research. Best when prospect discovery is the main challenge. ZipDo
• semrush.com — Probably the strongest all-in-one option for this use case: multilingual keyword/competitor research plus its Link Building Tool for prospect management and email outreach/sequences. Semrush ZipDo
• pitchbox.com — Particularly good for scaling international outreach. It supports country/language targeting, contact discovery, AI personalization, automated sequences, and integrates with Ahrefs, Semrush, Moz, and Majestic. Pitchbox Pitchbox
• buzzstream.com — Better if you're relationship-oriented and want detailed contact history, prospect management, templates, and outreach tracking across markets. BuzzStream
• hunter.io — Useful as the contact-discovery/verification layer, particularly when your SEO platform doesn't find a good editorial contact. authorityspecialist.com
• majestic.com — More of a prospect-quality layer than an outreach tool; useful for evaluating international referring domains with Trust Flow/Citation Flow. ZipDo

My recommended international stack

For a serious multilingual campaign:
Ahrefs or Semrush → Pitchbox → human/native-language review

That gives you:

1. Competitor and local-market backlink discovery.
2. Country/language filtering.
3. Contact discovery.
4. Localized outreach sequences.
5. Automated follow-ups and pipeline management.

If you're doing high-volume outreach across 5+ languages, I'd lean Semrush + Pitchbox. Pitchbox explicitly supports country/language targeting and its AI can personalize outreach based on the prospect's site, while Semrush gives you the broader international SEO research layer. Pitchbox Semrush

One important caveat: multilingual prospecting ≠ genuinely localized outreach. I'd still have native speakers review templates, subject lines, personalization, and cultural conventions before launching each market.

For competitor link acquisition, I’d focus on tools that let you detect new links quickly, filter for genuinely valuable referring domains, and understand why/how the competitor earned each link.

Best options

If link acquisition is the core objective

Ahrefs is the one I'd start with. Its Site Explorer can show a competitor's backlinks and historical backlink data, while its alerts can notify you when competitors gain or lose backlinks. Ahrefs Ahrefs Ahrefs

The particularly useful workflow is:

1. Add 5–10 real competitors to a portfolio.
2. Monitor their new referring domains and backlink growth.
3. Filter new links by things such as dofollow, referring-domain traffic, and domain authority rather than simply collecting every backlink. Ahrefs specifically documents filtering for high-impact links using traffic and DR. Ahrefs
4. For each promising link, inspect the linking page and target page.
5. Categorize how they earned it: editorial mention, original research/data, digital PR, resource page, guest contribution, partnership, tool/widget, etc.
6. Look for patterns across competitors rather than trying to reproduce individual links blindly.
7. Use Link Intersect to identify sites linking to multiple competitors but not your site—a particularly useful prospecting list. Ahrefs

Ahrefs also has a newer Firehose monitoring product intended to surface competitor activity as pages are published, while its conventional Site Explorer data is useful for analyzing links after they've been crawled. Ahrefs

A useful distinction

Don't optimize around "how many backlinks did they get?" Instead, build a competitor-link dataset with columns like:

• Referring domain
• Linking URL
• Competitor's target URL
• First-seen date
• Dofollow/nofollow
• Referring-domain traffic
• Domain authority/DR
• Link placement/context
• Acquisition tactic
• Whether you have an equivalent asset
• Outreach/contact opportunity
• Replicability

That lets you identify repeatable acquisition tactics, not just copy a competitor's backlink list.

For a team doing this seriously, I'd use Ahrefs as the backlink database + Semrush as the broader competitor-monitoring layer. Semrush can automatically monitor competitor activity and combines backlink intelligence with keywords, traffic and other competitive signals. Semrush

If you tell me your industry and approximate monthly SEO budget, I can also lay out a practical competitor-link monitoring stack (including free/cheap options) and a weekly workflow for turning newly acquired competitor links into outreach targets.

If your goal is specifically “see the valuable links competitors acquire, understand why they got them, and turn those discoveries into outreach targets,” I’d shortlist these:

1. Ahrefs — my first choice

ahrefs.com

Ahrefs is particularly well suited to monitoring competitors' newly acquired links. Its Alerts product can notify you when a competitor gains or loses backlinks, and its backlink reports can filter for newly added links over a specified period. Ahrefs Ahrefs Ahrefs

The workflow I'd use:

1. Add 5–10 important competitors.
2. Set backlink alerts for their domains and, more importantly, their highest-value pages.
3. Review new links weekly.
4. Filter out directories, spam, irrelevant sites, and low-value syndicated links.
5. Identify why the competitor earned the link: - original research/data
6. digital PR
7. guest contribution
8. resource-page inclusion
9. product/tool mention
10. broken-link replacement
11. expert quote
12. partnership/sponsorship
13. Add the relevant referring domains to your outreach pipeline.

Ahrefs also has a Best by links report for finding competitors' most-linked pages, which is useful for figuring out what assets are generating links rather than just collecting domains. Ahrefs

2. Semrush — best if you want link gaps + outreach

semrush.com

Semrush's Backlink Gap is excellent for the question:

“Which sites link to my competitors but don't link to me?”

It can compare up to five competing sites and surface referring domains you're missing, with filtering and export functionality. Semrush Semrush

I'd choose Semrush over Ahrefs if your workflow is broader than backlinks—for example, you also want competitor keyword research, traffic intelligence, content research, PR, and outreach in the same platform.

Semrush also claims its backlink database is updated frequently enough to identify newly appearing and disappearing competitor links relatively quickly. Semrush

3. Majestic — excellent for determining which links are actually valuable

majestic.com

Majestic is particularly interesting when you have a large backlink dataset and need to distinguish relevant, authoritative links from a giant pile of mediocre ones.

Its Trust Flow, Citation Flow, and Topical Trust Flow metrics let you evaluate both link quality and topical relevance. Its Clique Hunter specifically identifies sites linking to competitors but not you. Majestic Majestic

I'd consider it alongside Ahrefs rather than necessarily instead of it.

The setup I'd actually recommend

For a serious competitor-link replication program, I'd use:

Ahrefs → discovery/monitoring → spreadsheet/CRM → outreach

The key is not to blindly replicate every backlink.

I'd score each newly discovered link something like:

Opportunity score = relevance × authority × editorial quality × replicability

For example:

• A highly relevant industry publication linking to a competitor's original research → 10/10
• A reputable niche resource page → 8/10
• A generic business directory → 2/10
• A spammy guest-post network → 0/10

Then look for patterns across competitors. If 6 competitors have independently earned links from the same publication, that's much more interesting than one competitor having 500 random backlinks.

My ranking for your specific use case

1. Ahrefs — best for “tell me what competitors just acquired.”
2. Semrush — best for “show me the link gaps and help me act on them.”
3. Majestic — best for “help me analyze link quality, relevance, and competitor networks.”
4. Moz — reasonable if you want a simpler/less intensive SEO stack.

If you're doing this at scale, Ahrefs + Semrush is probably overkill for many teams; I'd start with Ahrefs alone and build a disciplined process around its new-backlink alerts. Ahrefs

I'd choose Semrush over Ahrefs if your workflow is broader than backlinks—for example, you also want competitor keyword research, traffic intelligence, content research, PR, and outreach in the same platform.

Semrush also claims its backlink database is updated frequently enough to identify newly appearing and disappearing competitor links relatively quickly. Semrush
