Backlink Gap Analysis: Steal Competitors’ Links (2026)

By Mubashir Safeer✓Updated 12 Oct 202610 min read

Your competitors are ranking above you for a reason, and in most cases that reason is links. A backlink gap analysis finds the websites that link to your competitors but not to you — which is essentially a ready-made list of link opportunities someone else already validated. Instead of guessing where to get links, you work from a list of sites that have already proven they link to businesses like yours. practical methods to check competitor backlinks.

This guide walks through the full method: how to pick competitors, how to find the gaps (with paid tools and with free methods), how to decide which opportunities are worth chasing, and how to actually win the links.

What Is a Backlink Gap?

A backlink gap is the set of referring domains linking to your competitors but not to your site. The “gap” is the difference between their link profile and yours.

The idea is simple: if a blog, directory, podcast, or news site linked to three of your competitors, there is a good chance it would link to you too — provided you give it a reason. These sites have already demonstrated two things: they publish content in your niche, and they are willing to link out to businesses like yours. That makes gap links some of the highest-converting link prospects you will ever find, because the hardest part of link building (finding sites that say yes) is partly done.

A backlink gap analysis is just the process of computing that difference systematically instead of stumbling onto it by accident.

Why Gap Analysis Beats Random Link Building

Most beginners build links backwards. They brainstorm “link building tactics” — guest posts, directories, HARO-style outreach — and then hunt for targets. Gap analysis flips it: you start with targets that are already proven, then pick the tactic that fits each one.

Three reasons this works better:

1. Relevance is pre-validated. A site linking to your direct competitors is, by definition, topically relevant to your business. Relevance is one of the few things everyone agrees matters in link quality.

2. You skip the “will they link?” gamble. Cold outreach to random blogs converts at low single-digit percentages. Outreach to a site that already links to two competitors converts far better, because linking to businesses in your space is already their normal behavior.

3. It reveals competitor strategy. The gap list shows you how competitors built their profiles — which directories they submitted to, which podcasts they appeared on, which resource pages list them. You are not just copying links; you are reverse-engineering their playbook.

Pick the Right Competitors

Garbage in, garbage out. The quality of your gap list depends entirely on which competitors you analyze.

Pick 3–5 competitors, not 20. You want sites that compete with you for the same keywords and serve the same audience. Good candidates:

• Sites ranking on page 1 for your target keywords
• Direct business competitors (similar product, similar customer)
• One aspirational competitor — a bigger site in your niche whose link profile you want to grow into

Avoid these: Wikipedia, Amazon, giant news sites, and aggregators. Their link profiles are so large and generic that the “gaps” will be noise — thousands of domains that will never link to a small site.

A practical test: if you would be happy to be mentioned alongside that site in an article, it is a good competitor for gap analysis. If the comparison makes no sense, drop it.

Export Their Backlinks

You need each competitor’s referring domains in a spreadsheet. Two routes:

The paid route (fast)

• Ahrefs: Site Explorer → enter competitor domain → Backlinks, or use Link Intersect (enter your domain + up to 10 competitors; it shows who links to them but not you). Link Intersect is purpose-built for exactly this.
• Semrush: Backlink Analytics → Backlink Gap tool. Enter your domain and up to 4 competitors; it outputs the gap table directly.
• Moz: Link Intersect inside Link Explorer does the same job.

These tools do the differencing for you and add metrics (authority scores, traffic, follow/nofollow) that make prioritization easy. If you do gap analysis regularly, one of these subscriptions pays for itself.

You can check any site’s authority for free with our website authority checker.

The free route (slower, but works)

No budget? You can still do a useful gap analysis manually:

1. Google your competitors’ brand names. Search "competitorname" -site:competitorname.com to find pages mentioning them. Mentions often come with links.
2. Check obvious link sources directly. Look at their site footer, partners page, “as featured in” sections, and press pages — these reveal directories, podcasts, and publications that linked to them.
3. Use search operators for link patterns. Queries like "competitorname" + "guest post", "competitorname" + "interview", or "competitorname" + "podcast" surface the coverage that earned them links.
4. Mine “best of” and resource lists. Search best [your niche] tools, top [your niche] blogs, [your niche] resources — if competitors appear on lists you don’t, that is a gap you can close by pitching the list owner.
5. Check their testimonials and reviews. Competitors often have testimonial pages on tools they use — those pages usually link back. If you use the same tools, you can earn the same links.

The free method will not give you their entire link profile, but it reliably surfaces the most valuable gaps: the editorial links, podcasts, and lists — which are exactly the links worth chasing anyway.

Find the Actual Gaps

With paid tools, this step is automatic — the gap report is the output. Manually, you are building a simple spreadsheet:

Any row where at least one competitor has a “Yes” and you have a “No” is a gap. Sort or filter so the domains linking to the most competitors float to the top — a site linking to three competitors is a far hotter prospect than one linking to a single competitor once.

Deduplicate and clean. Remove: social media profiles, the competitors’ own domains, obvious spam, and sites in languages you cannot work with. What remains is your prospect list.

Prioritize Ruthlessly

A raw gap list might have hundreds of domains. You cannot chase them all, and you should not — a handful of excellent links beats dozens of mediocre ones. Score each prospect on four factors — and check DA and DR in bulk to score hundreds of domains at once:

1. Authority and traffic. Prefer sites with real traffic and solid authority metrics. A link from a site nobody visits still counts, but a link from a site with an actual audience can send referral traffic too. When comparing authority scores across tools, remember how DA differs from DR — they measure different things, so use one tool consistently.

2. Relevance. A link from a niche-relevant site beats a link from a random high-authority site. Rank prospects by how closely their content matches your topic.

3. Link type. Editorial links inside content (a blog recommending you, a podcast episode page, a resource list) are worth far more than footer links, author-bio links, or directory listings. Note the type of link each competitor got — that tells you what you need to earn.

4. Winnability. Be honest: can you actually get this link? A New York Times mention is a gap for everyone; it is not an actionable prospect. Prioritize sites where you can see a clear path: they accept guest posts, they interview founders, they maintain a resources page, they list tools in your category.

A simple scoring approach: rate each prospect 1–3 on relevance, authority, and winnability, and work the 9s first, then 8s, then 7s. Anything below 6 goes on a “someday” tab.

Win the Links (Outreach That Works)

Knowing the gaps is half the job. Now you have to earn the links — and the pitch writes itself, because you know why each site links to businesses like yours.

Match the tactic to the link type:

• They linked to a competitor’s guest post? Pitch your own guest post on a complementary angle. Mention (lightly) that you noticed they cover this topic — do not say “you linked to my competitor, now link to me.”
• They interviewed a competitor on their podcast? Pitch yourself as a guest with a specific topic, not a generic “I’d love to be on your show.” Podcast backlinks are among the easiest gap links to close because hosts always need guests.
• They list competitors on a resources/tools page? Send a short note: your tool/resource exists, here is why their readers would benefit, one link to check it out. Keep it under 100 words.
• They reviewed a competitor? Offer your product for review, or suggest an updated roundup that includes you.
• Directory or association listing? Just submit. Many gap links are listings the competitor bothered to claim and you did not.

Outreach pointers that actually matter:

• Lead with what’s in it for them, not your link request. A guest post pitch leads with the article idea; a resource page pitch leads with the value to their readers.
• Keep it short. Under 150 words for cold outreach. Long emails do not get read.
• One ask per email. Do not pitch a guest post and a link insertion and a podcast appearance in the same message.
• Follow up once, 7–10 days later. One polite bump meaningfully lifts replies; more than that burns the relationship.
• Never offer payment for editorial links. Paid links violate Google’s guidelines and can get both sites penalized. Directories with legitimate listing fees are a different category — but a blog “selling” a guest post link is not.

If you are just starting out and your site is brand new, pair gap outreach with a safe backlink plan for a new website so your overall link velocity looks natural while you chase these higher-value targets.

Common Backlink Gap Mistakes

Copying every link blindly. Some competitor links are bad — link farms, paid placements, spammy directories. If a linking domain looks shady, not having that link is a competitive advantage. Audit before you copy.

Ignoring the links you already have. Run the analysis in reverse too: which sites link to you but not competitors? Those are your moat. Make sure those relationships stay strong.

Doing it once and forgetting it. Competitors keep building links. Re-run your gap analysis quarterly. New gaps appear constantly — a competitor’s podcast tour this quarter is your prospect list next quarter.

Chasing only high-authority domains. A relevant DR-30 blog that sends you five qualified visitors a month beats an irrelevant DR-70 link that sends nothing. Authority is one input, not the decision.

Targeting competitors that are too big. If you analyze Amazon’s link profile as a small SaaS, every “gap” will be unactionable. Keep competitors within a reasonable size range of your own site.

How Often Should You Run a Backlink Gap Analysis?

For most small sites: a full gap analysis once per quarter, plus a quick monthly check on your 2–3 closest competitors for new links worth reacting to. Link building compounds — the prospects you uncover in Q1 become the relationships that produce links in Q2 and Q3.

The Bottom Line

Backlink gap analysis is the highest-leverage link building activity for most sites because it replaces guessing with evidence. You are not wondering where to get links — you are working a list of sites that already link to businesses exactly like yours.

The method in brief: pick 3–5 real competitors, export their referring domains (paid tool or manual research), difference them against your own profile, prioritize by relevance × authority × winnability, and outreach with a tactic matched to each link type. Do it quarterly, skip the shady links, and follow up once.

Start with the sites linking to multiple competitors — those are the warmest prospects on your list, and they are usually where the first wins come from.

Frequently Asked Questions

What is backlink gap analysis in simple terms?

It is the process of finding websites that link to your competitors but not to you. Those “gap” sites are proven link prospects because they already link to businesses in your niche, making them far more likely to link to you than a random site.

Which tool is best for backlink gap analysis?

Ahrefs’ Link Intersect (up to 10 competitors), Semrush’s Backlink Gap (up to 4 competitors), and Moz’s Link Intersect all do it well — they compare your domain against competitors automatically and output the gap table. If you have no budget, you can do a manual version using Google searches for competitor brand mentions, podcast appearances, and “best of” lists.

How many competitors should I analyze?

Three to five. Fewer than three gives you a thin prospect list; more than five creates noise. Choose direct competitors ranking for your keywords, plus optionally one larger aspirational site in your niche.

Should I copy all of my competitors’ backlinks?

No. Audit the gap list first and skip shady links — link farms, paid placements, and spammy directories. Copying a competitor’s toxic links does not help you; it just imports their risks. Prioritize relevant, editorial links from real sites.

How long does backlink gap analysis take?

With a paid tool, the analysis itself takes under an hour; manual research takes a day or two. Outreach is the long part — expect weeks to convert prospects into live links. Re-run the analysis quarterly to catch new gaps.

Can beginners do backlink gap analysis for free?

Yes. Search for competitor brand mentions (“competitor” -site:competitor.com), look for their podcast interviews and guest posts with search operators, and check “best of” lists in your niche. You will not get their full link profile, but you will reliably find the most valuable gaps — the editorial links worth chasing.
