How to Do a Competitor Backlink Gap Analysis and Turn It Into a Link-Building Campaign

If your competitors are consistently outranking your website, their backlink profiles can reveal something important: where your SEO strategy is falling behind.

A competitor backlink analysis allows you to examine the websites linking to competing pages, identify authoritative domains you do not have links from, and uncover patterns in how competitors are earning links. But simply exporting a list of competitor backlinks is not enough.

The real value comes from turning that information into a backlink gap analysis and an actionable link-building strategy.

Here is how to do it step by step.

What Is a Competitor Backlink Analysis?

A competitor backlink analysis is the process of examining the backlinks pointing to your competitors' websites or specific pages.

The goal isn't to copy every link they have. Instead, you want to understand:

• Which websites link to your competitors

• Which competitors have the strongest backlink profiles

• What types of content attract the most links

• Which publications and websites repeatedly link within your industry

• Which relevant opportunities your website has not yet captured

This gives you a clearer picture of the competitive link landscape.

For example, if three competitors have backlinks from the same industry publication while your website has none, that publication represents a potential link-building opportunity.

What Is a Backlink Gap Analysis?

A backlink gap analysis takes competitor backlink analysis one step further.

You compare your backlink profile with those of your competitors to identify link opportunities that your competitors have but you don't.

Imagine that you analyze three competing websites and discover that:

• Competitor A has 12 links from industry publications

• Competitor B has 9

• Competitor C has 15

• Your website has only 3

The important question isn't simply how many backlinks you're missing. It is which links are realistically worth pursuing.

A backlink gap analysis helps you separate potentially valuable opportunities from irrelevant or low-quality links.

Step 1: Identify Your Real SEO Competitors

Start by choosing competitors carefully.

Your biggest business competitors aren't necessarily your biggest SEO competitors. A website may compete with you commercially but rank for completely different keywords.

Look for websites that consistently compete with your pages in organic search.

Ideally, select three to five competitors with similar:

• Target audiences

• Products or services

• Search intent

• Content topics

• Geographic markets

Using several competitors is useful because recurring patterns become easier to identify.

If the same website links to multiple competitors, for example, it may be particularly relevant to your link-building campaign.

Step 2: Analyze Competitor Backlinks

Use a backlink analysis tool to examine each competitor's link profile.

For each backlink, look at factors such as:

Referring domain: Which website is providing the link?

Link relevance: Is the referring website actually related to your industry or topic?

Authority: Does the website have a strong and established backlink profile of its own?

Link placement: Is the backlink naturally included within editorial content, a resource page, a directory, or another type of page?

Target page: Which competitor page receives the backlink?

Anchor text: How is the competitor being referenced?

You are looking for patterns, not just numbers.

A competitor with thousands of backlinks may have fewer useful opportunities than a competitor with a smaller but highly relevant backlink profile.

Step 3: Find the Actual Backlink Gaps

Now compare your backlink profile against your competitors.

Create a list of referring domains that link to one or more competitors but don't currently link to your website.

These are your potential backlink gaps.

However, don't immediately add every domain to your outreach list.

A domain becomes more interesting when it satisfies several conditions:

It is relevant.
The website operates within your industry or covers topics connected to your audience.

It has authority.
The domain demonstrates genuine credibility rather than existing primarily to sell links.

It sends useful signals.
The website has legitimate content, an established audience, or meaningful organic visibility.

There is a logical reason to link to you.
Your website needs something valuable enough for the publisher to reference.

That final point is crucial.

A backlink gap is an opportunity, not a guaranteed backlink.

Step 4: Analyze Why Competitors Earned the Link

This is where competitor backlink analysis becomes much more useful.

Don't just ask:

"Where did my competitor get a backlink?"

Ask:

"Why did they get this backlink?"

Open the referring page and examine the context.

Perhaps the competitor was mentioned because it published original research.

Maybe it created an industry statistic that journalists referenced.

Perhaps the competitor has a detailed guide that another website recommends as a resource.

Or the backlink may have been earned through a Digital PR campaign.

Understanding the reason behind the link helps you develop a strategy for earning a similar opportunity.

Instead of copying the competitor's backlink, you can replicate the underlying linkable asset or campaign mechanism.

Step 5: Group Opportunities by Link-Building Tactic

Once you have your backlink gaps, organize them into categories.

For example:

Editorial Opportunities

Publications, blogs, and industry websites that could naturally reference your content.

Resource Pages

Websites maintaining curated lists of useful resources.

Digital PR

Journalists and publications that could potentially reference original research, data, expert commentary, or newsworthy campaigns.

Guest Contributions

Relevant websites that accept expert contributions where appropriate.

Link Reclamation

Websites that previously linked to your brand or content but have removed or changed the link.

Competitor Content Opportunities

Pages linking to competitor resources where your content could provide an equally useful or better alternative.

This categorization turns a raw backlink database into a practical link building strategy.

Step 6: Prioritize the Best Opportunities

Not every backlink gap deserves outreach.

Create a scoring system to prioritize opportunities based on factors such as:

• Relevance

• Domain authority

• Organic traffic

• Editorial quality

• Link placement

• Likelihood of earning the link

• Relationship with your industry

• Potential referral traffic

For example, a highly relevant industry publication that links to three of your competitors could be more valuable than dozens of unrelated websites with higher domain metrics.

The goal isn't to maximize the number of prospects.

It's to maximize the quality and strategic value of the prospects you pursue.

Step 7: Build the Campaign Around Your Findings

Now turn your prioritized opportunities into an actual campaign.

Your campaign should define:

Target pages: Which pages need backlinks?

Target domains: Which websites are you pursuing?

Linkable assets: What content, research, tools, or resources will you offer?

Outreach angle: Why would the publisher want to reference your resource?

Acquisition method: Are you using Digital PR, outreach, content promotion, reclamation, or another tactic?

KPIs: What will you measure?

Instead of launching one generic outreach campaign, create smaller campaigns around specific opportunity groups.

For example, 30 industry publications may require a different approach from 50 resource pages or 20 Digital PR prospects.

Step 8: Measure Results and Update the Gap

After your campaign launches, track the results.

Measure metrics such as:

• Outreach response rate

• Links acquired

• Referring domains gained

• Link relevance

• Target pages receiving links

• Referral traffic

• Ranking changes

• Organic traffic changes

Then repeat the competitor backlink analysis periodically.

Your competitors will continue earning new backlinks, while websites may remove, replace, or change existing links.

That means your backlink gap is not a one-time report.

It can become an ongoing source of link-building opportunities.

Turn Competitor Backlinks Into a Strategy

A competitor backlink analysis becomes powerful when you stop treating it as a spreadsheet exercise.

The objective isn't to collect thousands of competitor backlinks. It's to identify repeatable opportunities, understand why those links were earned, and build campaigns that give publishers a genuine reason to link to your website.

Start with a small group of genuine SEO competitors. Identify the domains linking to them but not to you. Filter those opportunities for relevance and quality, determine why each competitor earned the link, and then organize the strongest prospects into focused campaigns.

Done properly, a backlink gap analysis can transform competitor data into a practical link building strategy—one that is based on what is already working in your search landscape while still giving you room to create something better.
