Competitor backlinks: how to check, qualify and earn them

Competitor backlinks: how to check, qualify and earn them

Competitor backlink analysis shows which pages and referring domains help rival sites win links, then turns that evidence into a prospect list. The loop is simple: choose real search competitors, pull their backlink data, find domains linking to them but not you, qualify each prospect for relevance and quality, then earn the link with a reason an editor can accept.

The competitor backlink loop

Do not start by exporting every link from every site in your market. That creates a large file and a weak plan. Start with a tight workflow:

1. Pick the competitors that share your search market.
2. Pull their backlinks in one primary tool.
3. Find the gap: referring domains they have and you do not.
4. Remove poor fits, weak pages and spam risk.
5. Group the remaining prospects by the kind of link you can earn.
6. Track new, lost and won links over time.

That sequence keeps the work practical. You are not trying to copy a rival's whole backlink profile. You are trying to find the small set of sites that already link to content like yours and might have a fair reason to mention you.

1. Choose competitors that can teach you something

Business competitors and search competitors are not always the same. A company can sell the same service as you and still rank for a different set of terms. Another site may not sell what you sell, but it may own the search results you need.

Build two competitor lists.

Your domain-level list should include sites that compete across several money or informational keywords. These are useful for broad link gap work because their backlink patterns show which publishers, directories, resource pages, associations and blogs often cover the niche.

Your page-level list should include URLs ranking for the exact topic you want to improve. These are useful when one article, service page or tool is underperforming. A page-level comparison is often cleaner than a domain-level comparison because it shows links earned by that asset, not by the whole brand.

Use search results first. Search your primary keyword, the secondary terms, and a few buyer variants. Record the domains that appear again and again. Then sense-check those domains by looking at website traffic, ranking breadth and topical overlap. You do not need perfect matches. You need competitors whose links could plausibly make sense for your own site.

Remove outliers before you export data. Huge media sites, marketplaces, social networks and government domains can distort the list. Keep them only if they are genuine rivals for the page or keyword you are studying.

2. Pull the backlink data

Use one tool as the source of the export, then cross-check important prospects elsewhere if you need confidence. Mixing four exports at the start usually creates duplicate work because each index crawls the web differently.

Ahrefs: Site Explorer and Link Intersect

In Ahrefs, start with Site Explorer. Enter the competitor domain or competing URL, then review the backlink profile, referring domains, linked pages and anchor data. This gives you the shape of the site: which pages attract links, which domains link more than once, and which link types repeat.

Then use Link Intersect. Add two or more competing domains as the sites to compare, and set your own domain as the one to exclude, so the tool returns domains that link to your rivals but not to you. The result is the core gap list: sites linking to competitors but not to you.

Sort this list by referring domain quality and overlap, but do not treat the top rows as automatic wins. A domain that links to three competitors is interesting. It is not yet a prospect until the linking page, topic and link reason make sense.

Semrush: Backlink Analytics and Backlink Gap

In Semrush, use Backlink Analytics when you want to inspect one competitor. Review the backlinks, referring domains, linked pages and anchor data. This is the profiling step.

Use Backlink Gap when you want the comparison step. Enter your domain and the competitor domains, then look for referring domains that link to them and not to you. Pay close attention to domains that link to more than one rival because those sites have already shown repeated interest in the topic.

Semrush also surfaces Authority Score and backlink categories. Treat those as sorting signals, not final decisions. The page itself still decides whether the link belongs on your outreach list.

Majestic: Comparator and Clique Hunter

Majestic is strongest here when you want a link-comparison view rather than a single-site audit. Use Comparator to compare domains side by side, then move into Clique Hunter to find sites that link to several competitors.

Clique Hunter is useful because it pushes you towards shared referring domains. That matters. A publisher that links to one rival may have made a one-off citation. A publisher that links to three relevant rivals is more likely to cover the category.

Use Trust Flow and Citation Flow as screening metrics inside Majestic. They can help you sort the list, but they should not overrule relevance. A lower-metric site that is tightly relevant can be a better prospect than a higher-metric site with no editorial fit.

Moz: Link Explorer

Moz Link Explorer is still useful for a second look at a backlink profile. It can show linking domains, inbound links, anchor text, Domain Authority and Page Authority. Use it to confirm whether a site has a real link footprint and to catch prospects another index missed.

Do not build the whole workflow around Moz if your main task is competitor link comparison. It is a helpful backlink analysis tool, but Ahrefs Link Intersect, Semrush Backlink Gap and Majestic Clique Hunter are the more direct gap workflows.

3. Find the actual backlink gap

A backlink gap is not "competitors have more links than us". That is too broad to act on. The useful gap is more specific:

• A referring domain links to a relevant competitor page but not to yours.
• The linking page is live, indexed and topically close enough.
• The link sits in a context where your page, product, data or article could fit.
• The site has an owner, editor or contributor route you can reach.

Export referring domains first, not every individual backlink. Domain-level review keeps the list manageable. If one referring domain has five links to a competitor, review the domain once, then inspect the individual linking pages after it passes the first screen.

Mark each domain with the competitor count. A domain linking to four rivals deserves a faster look than a domain linking to one. Then add the best linked competitor page, the link source page, the anchor, and the likely reason for the link.

The "reason" column is where the work becomes useful. Examples include:

• Resource page includes suppliers, tools or guides.
• Blog post cites a statistic or definition.
• Comparison page lists alternatives.
• Guest article links to a supporting resource.
• Local or industry directory lists relevant businesses.
• Partner page mentions vendors, members or case studies.

If you cannot write a clear link reason, the prospect is probably weak. Do not force it.

4. Qualify each referring domain

The best competitor backlink reports are smaller after review, not larger. Your first export is only raw material. Qualification decides what is worth outreach, content work or tracking.

Start with topical relevance. Ask whether the linking site covers your industry, your audience or the problem your page solves. A link from a relevant authoritative website is stronger than a random high-metric link from a site that never covers your topic.

Then inspect the linking page. Look for real editorial context. Is the competitor link inside useful body copy, a curated resource list, a comparison, a citation, or an author bio? Is the page maintained? Does it rank or receive traffic? Would a reader understand why your link belongs there?

Next, screen the domain. A quick quality check should cover:

• Topical focus: the site publishes about subjects close to yours.
• Editorial standards: pages look written for readers, not link sellers.
• Link placement: links sit in body copy or a useful list, not a crowded footer.
• Outbound pattern: the page is not stuffed with unrelated commercial links.
• Indexation: the page and domain are visible in search.
• Freshness: the site still publishes or updates content.
• Contact route: there is a realistic way to reach an editor or owner.

Use third-party metrics after those checks. Link authority, DR, DA, Trust Flow and similar scores can help you prioritise, but they are not Google metrics. If you are comparing DR or DA, use the same metric consistently inside one batch and avoid mixing scores as if they were interchangeable.

Anchor text matters too. A competitor link with natural anchor text is easier to learn from than a page full of exact-match commercial anchors. Use the anchor as a clue to the link reason. If the anchor is a brand name, the page may be about the company. If it is a statistic, definition or guide title, you may need content that answers the same need. If you need a refresher, this anchor text is the clickable text that appears in a hyperlink.

Score each prospect in plain language: pursue, maybe, monitor or reject. That is enough. A simple label is better than a fake precision score.

5. Decide how you can earn the link

Finding a gap does not mean you are entitled to fill it. The prospect still needs a reason to link to you.

Match each qualified prospect to one of four earning paths.

The first path is an existing-page mention. This works when the linking page already covers your topic and your page adds something useful. Once you have found the gaps, you still need to earn the links; curated links are one route when an existing relevant article can fairly reference your page without changing its purpose.

The second path is a guest contribution. This works when the site accepts expert articles and the competitor link came from a guest post, contributor page or editorial column. Use the competitor backlink as a clue, then build a better pitch around the site's audience. A list of guest post opportunities is useful only after you filter it for relevance and editorial standards.

The third path is content improvement. This works when competitors have links because they own the better asset: a guide, tool, original dataset, checklist, calculator or comparison page. In that case, outreach before improving your page is a waste. Build the asset first, then pitch the pages that already link to weaker alternatives.

The fourth path is relationship or partnership work. This applies to associations, suppliers, customers, events, podcasts, local groups and industry bodies. The link is often a by-product of a real relationship, not the first thing you ask for.

Do not put every prospect into outreach. Some gaps are only useful as market intelligence. If a competitor has links from irrelevant directories, old scholarship pages or obvious paid-link networks, the lesson is "avoid this", not "copy this".

6. Build the outreach list

Your outreach list should be smaller than your export and richer than a list of domains. For each prospect, keep:

• Referring domain.
• Linking page URL.
• Competitor page linked.
• Link reason.
• Suggested page on your site.
• Contact route.
• Earning path.
• Priority.
• Notes on risk or fit.

Write the suggested page before you write the email. If you cannot name the page you want them to cite, the prospect is not ready.

Your pitch should refer to the linking page, not to your desire for a backlink. For a resource page, explain why your page fits the list. For a citation, show what your page supports. For a guest post, lead with the idea and the audience value. For a comparison or alternatives page, explain the missing angle.

Keep the email short. Editors do not need your full SEO plan. They need to know what page you looked at, what you are suggesting, and why it helps their readers.

This is where broader link building techniques come back into the workflow. Competitor backlink analysis finds the map. The tactic you choose depends on the page, the editor and the asset you can offer.

7. Monitor your backlink profile after outreach

Competitor analysis is not a one-off export. Recheck your core competitors and your own backlink profile on a schedule. Monthly is enough for most sites. Weekly makes sense during an active campaign or after publishing a major linkable asset.

Track three things.

First, watch new referring domains. If a competitor starts picking up links from the same kind of site again and again, add those sites to the prospect pool. If you win a link, tag it against the original gap so you can see which workflow produced it.

Second, watch lost links. A competitor's lost link can become an opening if the old page disappeared, moved or stopped matching the citation. Your own lost links need a separate review because they may need redirects, reclamation or page updates.

Third, watch anchor and page patterns. If your new links all point to the homepage with generic anchors, you may be building brand mentions but not supporting the page you wanted to grow. If competitors keep earning links to a guide, tool or data page, that tells you the market values that asset type.

Keep a simple monthly note: new gaps found, prospects qualified, outreach sent, links won, links lost, and pages that need improvement. The note matters because backlink tools can make activity look like progress. The only useful progress is a better prospect list, better assets and earned links from relevant sites.

Common mistakes to avoid

Do not chase every link a competitor has. Some links are old, accidental, paid, low quality or tied to relationships you cannot recreate. Copying them can waste time or add risk.

Do not treat domain metrics as the whole decision. Metrics help you sort, but page relevance and link context decide whether a prospect belongs in the campaign.

Do not pitch before your page is good enough. If the competitor earned a link to a detailed guide, a thin service page is unlikely to replace it.

Do not ignore page-level competitors. Domain-level gaps are useful, but page-level gaps usually produce cleaner outreach because the link reason is clearer.

Do not let the export define the strategy. Your strategy is the earning path: content, outreach, partnership, guest contribution, reclamation or no action.

FAQs

How do I check competitor backlinks?

If you want to know how to check competitor backlinks, start with a few close competitors — three is a sensible default. Enter their domains or ranking URLs into a backlink tool, review their referring domains, then use a gap workflow to find domains linking to them but not to you. Ahrefs Link Intersect, Semrush Backlink Gap and Majestic Clique Hunter are built for this comparison.

What is the best tool for competitor backlink analysis?

There is no single best tool for every team. Ahrefs is strong for Site Explorer and Link Intersect. Semrush is useful for Backlink Analytics and Backlink Gap. Majestic is useful for Comparator and Clique Hunter. Moz Link Explorer is useful as a second view of links, anchors and authority metrics.

Should I copy all competitor backlinks?

No. Copy the lesson, not the whole backlink profile. A competitor link is worth pursuing only when the referring domain is relevant, the page has real editorial context, and you can offer a page or asset that deserves the mention.

How many competitors should I analyse?

Start with three. Use one close business competitor, one search competitor that ranks across the topic, and one page-level competitor for the exact keyword. Add more only if the gap list is too small or the same referring domains keep appearing.

How often should I rerun the analysis?

Run a full comparison monthly if link building is active. For quieter sites, run it quarterly and add smaller checks after major content launches, competitor campaigns or ranking changes.

What makes a referring domain a good prospect?

A good prospect is relevant, editorially real, reachable and linked to a competitor for a reason you can match or improve. If the only appeal is a high metric, leave it out of the outreach list.
