Competitor Backlink Analysis: How to Find and Win the Links Your Rivals Have

Why Competitor Backlinks Are a Useful Starting Point

Cold link prospecting — searching for sites to contact without prior qualification — produces large prospect lists where most targets have shown no prior engagement with your topic. Competitor backlink analysis starts from a different position: you are looking at domains that have already referenced businesses or resources in your market, giving you evidence worth investigating rather than a blank slate.

That evidence is not automatic qualification. A backlink tells you that a particular page on another site linked to a competitor at some point. It does not tell you why. Before treating any competitor link as an opportunity, determine:

• Was the link editorial, paid, directory-based, relationship-driven, or user-generated?
• Does the linking page serve the same audience as your business or content?
• Could your business or content legitimately earn a comparable reference?
• Is the acquisition pattern something you can realistically reproduce?

The methodology that follows treats competitor backlinks as a discovery and investigation workflow — not a shopping list to contact in bulk.

Step 1: Identify the Right Competitors to Analyse

Not all business competitors are SEO competitors. A direct business competitor may have a completely different content strategy and backlink profile from the sites competing with you in organic search. Analyse both:

• Organic search competitors: Sites ranking on the first page for your primary target keywords. In Ahrefs: Site Explorer → your domain → “Competing Domains.” In Semrush: Organic Research → “Competitors” tab.
• Direct business competitors: Companies you compete with for customers, regardless of SEO performance. Their link profiles reveal industry-relevant publishers, associations, directories, and outlets you may want to be on, independent of search traffic.

Start with a manageable set of the most relevant competitors, then expand until additional profiles produce few genuinely new link patterns or prospect categories. The appropriate number depends on market size, niche diversity, and how much backlink-profile overlap exists. Use marginal information gain as the stopping rule — not a fixed competitor count.

Step 2: Export Referring Domain Data

In Ahrefs

1. Site Explorer → enter competitor domain → “Referring Domains”
2. Do not automatically exclude nofollow, ugc, or sponsored links at this stage — Google treats these attributes as hints rather than enforcement directives (Google link attribute guidance). Record link attributes as a qualification dimension rather than a discovery filter. A link from a qualified publisher remains useful intelligence even if the specific attribute is not a conventional followed editorial link
3. Sort by Domain Rating as an optional comparative triage field — not as the primary definition of link quality
4. Export to CSV
5. Repeat for each competitor

In Semrush

1. Backlink Analytics → enter competitor domain → “Referring Domains”
2. Include followed and qualified links; do not exclude nofollow or sponsored at discovery stage
3. Sort by Authority Score as a comparative triage field
4. Export to CSV
5. Repeat for each competitor

You now have a CSV per competitor listing every domain that has linked to them. The next step is classification, not contact.

Step 3: Classify Why Each Competitor Link Exists

Before running a gap analysis or building a prospect list, classify the acquisition type for each link. The classification determines which outreach tactic — if any — is appropriate. This step sits between data export and qualification because skipping it produces outreach mismatches: pitching editorial inclusion on a site that only links through paid placements, or asking for a replacement link when the competitor simply has a partner relationship.

For each referring domain, open the specific linking page and classify the link as one of:

• Editorial citation / evidence — the publisher cited the competitor’s page as a source, data point, or reference within independently written content
• Tool or resource listing — the linking page specifically lists tools, resources, or services useful to its audience
• Brand mention / PR coverage — the link appeared because the competitor was covered as a news subject, industry voice, or brand
• Relationship / community — guest contribution, interview, or contribution from the competitor’s team
• Directory or membership listing — the site organises businesses or resources in a structured, category-based format
• Sponsorship or commercial partnership — the link was acquired through a paid or commercial arrangement
• Customer / vendor relationship — the linking site and the competitor have a direct commercial relationship
• Affiliate or comparison page — the link appears in a product comparison, affiliate aggregator, or review context
• User-generated content — forum post, social thread, or community platform
• Broken or outdated resource — the competitor’s original page is dead or materially outdated
• Potentially manipulative — multiple warning signals suggest a link scheme; investigate before deciding, using Google’s link spam policies as a reference point for what constitutes manipulative link behaviour

Choose the outreach tactic based on link origin, not just domain metrics. A competitor’s editorial citation is investigated differently from their directory listing; a relationship-driven guest post requires a different approach from a broken resource.

Step 4: Link Gap Analysis — Find Domains Linking to Competitors But Not to You

A link gap identifies domains in competitor backlink profiles that do not yet appear in yours. This forms a candidate prospect set — not automatically the highest-priority targets. Priority depends on the acquisition type you identified in Step 3, the editorial context, and whether the pattern is realistically replicable.

In Ahrefs: Link Intersect

1. More → Link Intersect
2. Enter your domain in the “But doesn’t link to” field
3. Enter competitor domains in the “Show me domains that link to” fields
4. “Any target” mode shows domains linking to any competitor. “All targets” mode shows domains referencing all competitors simultaneously — useful for identifying publishers that repeatedly engage with your market, though repeat engagement alone does not establish editorial willingness to link to your business
5. Export results

In Semrush: Backlink Gap Tool

1. Link Building → Backlink Gap
2. Enter your domain and up to four competitor domains
3. Filter to domains linking to competitors but not to you
4. Use Authority Score as a comparative triage field alongside topical relevance and linking-page context

Without paid tools

Meaningful analysis requires access to a commercial backlink database. Paid tools make systematic competitor analysis substantially faster and provide broader discovery coverage. Free options include Ahrefs Webmaster Tools (your own domain only), Moz Link Explorer (limited free-tier lookups), and Majestic’s free tier. These support smaller analyses but typically expose less competitor backlink data or impose tighter usage limits.

Step 5: Qualify and Prioritise Prospects

Not every domain in the link gap is worth pursuing. Apply the following filters to build a qualified prospect list:

After filtering, maintain only prospects with a clear acquisition rationale. List size will vary substantially by niche, competitor set, market maturity, and qualification standards. Quality and replicability matter more than reaching a target prospect count.

Opportunity Priority Framework

Assign priority based on a combination of factors — not domain metrics alone:

• Relevance — how closely does the linking page’s topic and audience match your content?
• Link origin — what caused the competitor to earn this link, and is that cause legitimate and replicable?
• Replicability — can you authentically reproduce the conditions that earned the competitor’s link?
• Audience or referral value — does the linking site’s readership overlap with yours in a meaningful way?
• Editorial legitimacy — is this a site that independently evaluates and selects content, rather than selling links or listing everything in a category?
• Effort and fit — what content or relationship investment is needed, and does it align with your current resources and strategy?

Assign High / Medium / Low against each dimension. Prioritise the prospects scoring highest across the combination — not solely those with the largest third-party authority scores.

Step 6: Competitor Link Replicability Matrix

Not all competitor link types are equally actionable. Use this matrix to select the right response for each acquisition type you identified in Step 3:

Use this matrix before outreach — not to block investigation, but to select the right approach for each link type. A competitor’s resource-page inclusion and their guest contribution require fundamentally different responses.

Step 7: Content Gap Analysis — What Link-Earning Content Do Competitors Have That You Don’t?

Beyond which sites link to competitors, analyse what content on competitor sites attracts the most qualified referring domains. This reveals what formats and topics generate editorial citation interest in your niche.

In Ahrefs

1. Site Explorer → competitor domain → “Best by Links”
2. Sort by “Referring Domains” descending
3. Review competitor pages attracting the strongest and most relevant referring-domain patterns — continue until additional pages stop revealing materially new content formats, topics, or acquisition patterns

In Semrush

1. Backlink Analytics → competitor domain → “Indexed Pages”
2. Sort by “Referring Domains”
3. Identify highest-linked pages

For each highly-linked competitor page, ask: do you have comparable content? If not, that may be a content creation priority. If you do, investigate why publishers chose the competitor’s version. Possible explanations include original data, unique utility, stronger distribution, established brand recognition, better timing, a closer match to the citing page’s need, or a relationship the competitor built over time. Content depth alone rarely explains the full gap.

If credible, relevant publishers in your niche repeatedly cite original data studies or specific content formats, treat that as evidence that those formats fit the niche’s citation behaviour. Evaluate publisher quality and context, not just the percentage of competitor links that point to a given format.

Step 8: Outreach

Once you know which sites to approach and why the competitor earned each link, the outreach strategy becomes specific to the acquisition type:

Editorial citation — your content serves the same evidentiary need

Identify the specific page that linked to the competitor and read it in full. Understand what the competitor’s content contributed to that page’s context. Reach out only when your resource adds a distinct, useful contribution — new data, a different methodology, updated evidence, a tool, a missing perspective, or a function the existing reference does not provide:

Subject: Additional resource for your [article title] piece

Hi [Name], I came across your [article] on [topic].

I noticed you cited [competitor]’s [resource type] on [specific topic]. We published [your resource description] that covers [specific additional angle, more recent data, or distinct methodology] — it may be a useful additional reference for your readers on [specific point in the article].

[URL of your resource]

Happy to answer any questions about it.

[Name, Title, Company]

Do not ask for inclusion alongside a competitor simply because they are cited. Explain the specific additional value your resource provides to that page’s readers.

Original research — you need to produce comparable evidence first

If the competitor earned the link through original research, determine what specific evidence or dataset the publisher cited. To pursue a comparable opportunity, you may need genuinely original, current research that serves a similar evidentiary need. Producing equivalent content does not guarantee the same publisher will link — but it makes the pitch legitimate and relevant.

Broken or outdated competitor resource

When the competitor’s linked resource is dead or materially outdated, use the broken link building workflow: verify the link is dead, confirm your replacement matches the original’s intent and audience, assess fit, then pitch. See Broken Link Building: Complete Step-by-Step Guide for the full methodology.

Relationship-driven links (guest contributions, interviews)

If a competitor’s link resulted from a genuine editorial or professional relationship, treat it as relationship-driven rather than directly replicable from your current position. Build authentic industry relationships where there is mutual relevance. Do not manufacture engagement — commenting or engaging with a publication solely as a pretext for requesting a backlink — as this is evident to most editors and undermines the relationship you are trying to build.

Local competitor links

For local market analysis — identifying region-specific links, local directories, community sites, or geographic associations your competitor has — see Local Link Building: How to Earn Backlinks for a Local Business for tactics tailored to locally replicable opportunities.

Tracking Campaign Progress

Re-run the full analysis at a cadence appropriate to your market and campaign velocity — for example, after major competitor content launches, sustained outreach cycles, or meaningful changes in competitor backlink profiles. There is no universal cadence that fits every situation.

Common Mistakes

• Treating competitor backlinks as pre-qualified targets: A competitor link is evidence worth investigating. The classification step — determining why and how it was earned — is what makes the list actionable.
• Filtering out nofollow, ugc, and sponsored links during discovery: These link attributes are one dimension to record, not a reason to exclude a domain from discovery. A link with a nofollow attribute can still reveal a publisher, audience, relationship, or referral source worth understanding.
• Pursuing every domain in the link gap without filtering: Raw link gap lists contain opportunities that are irreplicable, irrelevant, or commercially inappropriate for your business. Classification and qualification before outreach is essential.
• Sorting by DR/AS as the primary priority model: Third-party authority scores are comparative triage tools. Topical relevance, linking-page context, editorial legitimacy, and acquisition replicability are more actionable priority criteria.
• Sending generic “please include me too” outreach: A competitor link is not evidence that a publisher needs another resource on the same topic. Explain the specific additional value your content or business provides to that page’s readers.
• Creating near-copies of competitor content to earn the same links: Adding genuinely distinct value — new evidence, stronger utility, updated data, a different methodology, a missing perspective — is what gives publishers a reason to cite your version. A close copy gives them no new reason.
• Confusing link gap with opportunity gap: Some competitor links exist because of relationships, historical events, acquisitions, or custom assets that cannot be reproduced. Identify which links represent replicable acquisition patterns before investing in outreach.

Frequently Asked Questions

What is the best tool for competitor backlink analysis — Ahrefs or Semrush?

Both Ahrefs and Semrush maintain large proprietary backlink databases, but coverage and freshness vary by domain, geography, crawl discovery, and update timing. Neither tool captures the web identically. For high-value campaigns, test a representative sample of your competitors in both tools rather than assuming one database is universally more complete. Using multiple databases increases discovery coverage because different crawlers find different links. The most effective choice often depends on which tool your team already uses for keyword research and which reporting workflows fit your process.

How do I tell if a competitor’s backlinks are from a link scheme I should avoid?

No single third-party metric or technical footprint proves a link scheme. Warning signs worth investigating include an implausible gap between authority scores and observable site activity, unrelated or thin outbound links, repetitive exact-match commercial anchor text, clusters of similarly structured sites, templated or low-quality content, and obvious link-selling behaviour. Investigate multiple signals together before classifying a source as manipulative. Shared hosting and low estimated organic traffic alone are not proof of a PBN or paid network — these conditions describe many legitimate sites too. If multiple strong warning signals appear together, avoid the source and move on.

Should I contact sites that link to competitors and ask them to replace the competitor’s link with mine?

Only when the situation genuinely calls for it. A replacement request is appropriate when the existing resource is dead, materially outdated, incorrect, or no longer serves the purpose cited — and your resource genuinely solves that problem. An additional-link pitch is appropriate only when your resource contributes a distinct, useful function relevant to the page’s readers. Do not ask for replacement or inclusion simply because a competitor is linked there — first determine why the link exists, then choose the approach that actually fits the context.

How long does it take to see ranking improvements from competitor backlink analysis?

There is no reliable universal timeline. Google must discover and process acquired links, and any ranking effect depends on the linking context, target page, competition, topical relevance, site quality, and other ranking changes happening at the same time. Track link discovery, indexing, target-page performance, and keyword positions over time, but do not assume a fixed delay between link acquisition and ranking movement, and do not attribute observed movement to backlinks alone. Third-party DR or Authority Score changes reflect vendor-specific crawl schedules — they are not evidence of Google’s evaluation of your backlink profile.

Can I use competitor backlink analysis to find paid link schemes and avoid Google penalties?

Competitor analysis can help you recognise link patterns worth avoiding. If similar patterns appear in your own profile, do not automatically reach for the disavow tool. Google states explicitly that most sites do not need to use disavow (Google Search Console Help — Disavow links to your site); use it cautiously and only after evaluating whether there is a substantial pattern of artificial links and a genuine manual-action concern or history. A competitor’s suspicious links are not links to your site and should not be copied simply because the competitor ranks — use competitor analysis to understand patterns, not to assume every link in a competitor’s profile is safe, valuable, or causal to their rankings.

What if all my competitors have far more backlinks than I do — where do I start?

Start with domains that show repeated, relevant engagement with your market, then classify whether that engagement is editorial, directory-based, commercial, relationship-driven, or another link type before prioritising the opportunity. Within that set, prioritise prospects where you have identified the specific acquisition reason, confirmed that your business or content fits the same context, and concluded that the pattern is realistically replicable. Build one strong piece of link-earning content for the most promising opportunity, then activate targeted outreach with that asset. Concentrate effort on a manageable number of well-qualified prospects rather than maximising outreach volume — this makes it easier to research the linking context, match the right acquisition tactic, and personalise the pitch appropriately.
