Your competitors have already done the hard work of identifying which sites will link in your niche. All you have to do is find those links and earn them too.
That is the logic behind competitor backlink analysis: a proven, repeatable process that gives you a pre-validated list of link opportunities. This guide walks through every step, from identifying the right competitors to analyse, through to replicating their best links, including the internal linking component that most guides skip entirely.
Definition
Competitor backlinks are the backlinks pointing to competing websites in your niche. Analysing these reveals which domains are willing to link to content like yours, what content earns links in your space, and where gaps exist in your own link profile compared to top-ranking pages.
The statistics on backlinks and rankings are stark. According to research by Backlinko, the number-one result on Google has 3.8 times more backlinks than pages ranked two through ten. And 95% of all web pages have zero backlinks, according to data from SEO PowerSuite.

Acquiring backlinks from scratch, with no roadmap, is slow and expensive. A single quality link costs an average of $509 according to Reporter Outreach. Competitor analysis changes the equation by giving you a pre-qualified prospect list: sites that have already demonstrated willingness to link to content in your niche.
Pages with backlinks from multiple referring domains are also dramatically more visible. Sites averaging 341 referring domains receive approximately 2,216 monthly visitors compared to just 383 for sites with around 101 referring domains, according to an Ahrefs study via LinkedIn. The correlation between referring domain diversity and traffic is strong.
Your SEO competitors are not necessarily your business competitors. They are the sites ranking above you for the keywords you want to own. Start by searching your target keywords in Google and noting who appears consistently in positions one through ten. These are the sites whose backlink profiles you need to study.
Tools like Ahrefs, SEMrush, and Moz Link Explorer all have competitor identification features that surface sites ranking for overlapping keyword sets. Export these to build your analysis list. Aim for three to five core competitors to analyse in depth.
Once you have your competitor list, pull their full backlink profiles using your chosen tool. For each competitor, you want to understand:
Filter out low-quality links from directories, forum spam, and unrelated niches. Focus on editorial links from topically relevant, higher-authority domains. These are the opportunities worth pursuing.
A backlink gap is a domain that links to one or more of your competitors but not to you. These represent your highest-priority opportunities: the site already links to content in your space, which means the bar to earning a link is lower than approaching a completely cold prospect.
The link intersect feature in Ahrefs (called Content Gap for backlinks) and the equivalent in SEMrush are built specifically for this. Enter your domain and up to four competitors, and the tool surfaces domains linking to them but not you, sorted by authority.

Broken link building is one of the most efficient replication tactics. When a competitor's page that earns links is deleted or moved without a redirect, the linking sites now point to a 404 error. If you have equivalent or better content, you can contact those linking sites and offer your page as a replacement.
Use Ahrefs' Site Explorer to check your competitors' pages for 404 errors that still have inbound links. Sort by the number of referring domains. Pages with five or more linking domains pointing to a broken URL are your best targets. Create or identify your existing content that covers the same topic, then reach out.
Replication does not mean copying. It means creating content that is better than what the linking site currently points to, then making the case for why your version deserves the link.
Many competitor links come from resource pages, industry roundups, and "best of" lists. These are relatively easy to earn. Email the page owner, introduce yourself, explain why your content would add value to their list, and ask for inclusion. Keep the email brief and specific: reference the exact page you found and why your content fits.
If a competitor has links from guest posts on relevant blogs, those publications are demonstrably open to contributions from your niche. Identify their guest post guidelines and pitch a topic that complements (but does not duplicate) what they have already published.
Understand what types of content earn the most links for your competitors. Is it original research? Comprehensive guides? Free tools? Templates? Focus your content creation on those formats. Then use the competitor link data to identify which publications to target with promotion.
This is the step that separates a good link building strategy from a great one. Every backlink you earn lands on a specific page. That page then has the opportunity to distribute authority through internal links to the rest of your site.
Most sites earn a backlink and leave the job there. But if the page that receives the link has weak or absent internal links to your priority pages, the equity stays confined. You want every page that earns links to act as a hub, distributing authority to your conversion pages and key ranking targets.
Linki automates this process. After you earn a competitor-replication link, use Linki to:
This step typically increases the impact of each earned link by a significant margin, because the authority does not stop at the landing page. See also our articles on conducting link audits and building topic clusters for topical authority.
Competitor backlink analysis is not a one-time activity. Competitors earn new links every week. Set up regular alerts in Ahrefs or SEMrush to notify you when a competitor earns a link from a new high-authority domain. Review these weekly and add promising new sources to your outreach pipeline immediately.
Track your own backlink acquisition against competitors over time. The relevant metric is not total backlinks but referring domain count and their average authority. A steady increase in diverse, relevant referring domains is the signal that your strategy is working.

Competitor backlinks are the external links pointing to websites that rank above you for your target keywords. Analysing them reveals which domains link to content in your niche, what content attracts links, and which sites represent the most accessible replication opportunities for your own link building efforts.
Ahrefs, SEMrush, and Moz all offer limited free access to backlink data. Ahrefs' free Backlink Checker shows the top 100 backlinks for any URL. Google Search Console reveals some linking domains for your own site. For thorough competitor analysis across multiple sites, a paid plan is worthwhile given the volume of data required.
The most capable tools for backlink gap analysis are Ahrefs (Link Intersect feature), SEMrush (Backlink Gap tool), and Moz (Link Intersect in Link Explorer). All three allow you to compare your backlink profile against multiple competitors simultaneously and identify domains linking to them but not you.
Replicate safely by focusing on editorial links earned through genuine content quality, not by purchasing links or using private blog networks. Create content that is demonstrably better or more useful than what the linking site currently points to. Personalise outreach, build real relationships, and avoid bulk link schemes that could trigger Google penalties.
