Competitor backlink analysis is one of the highest-ROI activities in link building because it converts an open-ended question — “where should I get links?” — into a specific, prioritized list of sites that have already demonstrated willingness to link to content in your space. Every link your competitor has is proof of concept: the site links to this topic, at this quality level, for content like yours. Your job is to find a reason for them to link to you too.
This guide covers the full process: pulling the data, filtering out the noise, categorizing the opportunities, and building an outreach plan from what remains.
Step 1: Choose Your Competitors Correctly
Competitor backlink analysis is most useful when you analyze the right competitors — which means your search competitors, not just your direct business competitors. Your search competitors are the sites ranking on the first page for your target keywords. They may or may not be direct business competitors, but their backlink profiles are the most relevant data set because those are the links that enabled those rankings.
How to find them: search your five most important target keywords in Google. Note every domain appearing in the top 5 results across those searches. The domains appearing most consistently are your primary search competitors. Build a list of three to five; more than five creates diminishing returns in the analysis phase.
Step 2: Pull the Backlink Data
Tools that provide backlink data for competitor domains:
- Ahrefs — the most comprehensive backlink index; Site Explorer → enter competitor domain → Backlinks report
- SEMrush — Backlink Analytics → enter domain → Backlinks tab
- Moz Link Explorer — free tier allows limited competitor analysis
- Majestic — strong for Trust Flow data; useful as a second opinion on link quality
For each competitor, export the full referring domains list (not individual backlinks — referring domains is the right unit of analysis). You want: the referring domain, its DR/DA, the anchor text used, the linking page URL, and whether the link is dofollow or nofollow.
Step 3: Filter the Data
A competitor with DR 50 may have 2,000 referring domains. Not all are worth pursuing. Filter the raw list down to actionable opportunities:
Remove the unreachable
- Links from the competitor’s own properties (subdomains, partner sites they own)
- Links from major news publications (NYT, Forbes, TechCrunch) that require genuine newsworthiness — not outreach targets unless you have a digital PR campaign planned
- Links from directories they submitted to — just submit yourself, no outreach needed
- Nofollow links from social platforms (Twitter, Facebook, LinkedIn profiles)
Prioritize by opportunity type
After filtering, categorize what remains into four buckets:
| Opportunity type | Approach | Priority |
|---|---|---|
| Resource pages that list competitors | Outreach to be added to the list | High — clear pitch, editor willing to add links |
| Roundup articles citing competitors | Pitch your tool/content as an addition or alternative | High — author already links to similar content |
| Guest post placements | Pitch your own guest post to the same publication | Medium — demonstrates the site accepts guest content |
| Editorial citations | Create content that rivals the cited piece; outreach | Medium — harder pitch but high-value if won |
| Directories not yet listing you | Self-submit | Quick wins — no outreach needed |
Step 4: Cross-Reference Across Competitors
The most valuable opportunities in a competitor backlink analysis are the sites that link to multiple competitors but not yet to you. A site that links to three of your five competitors is a site that clearly covers your topic area and has a demonstrated pattern of linking to similar content. This is your highest-priority outreach list.
How to find these in Ahrefs: use the Link Intersect tool (Site Explorer → Link Intersect → enter your domain plus competitors). It shows which domains link to some or all competitors but not to you. Sort by DR to find the highest-quality overlap opportunities.
Step 5: Identify Linkable Asset Gaps
Competitor backlink analysis reveals not just link sources but content gaps. Look at the pages on competitor sites that have earned the most links. These high-link-count pages tell you what types of content earn links in your niche — original research, comprehensive guides, free tools, comparison pages. If a competitor’s “Ultimate Guide to X” has 80 referring domains and you have no equivalent piece, that is a content gap as much as a link gap.
The action: build a better version of the highest-linked competitor pages. Not a copy — a genuinely better, more comprehensive, more current version. Then outreach to the sites linking to the original competitor piece: “I noticed you linked to [competitor’s guide] — I recently published a more comprehensive version that covers [specific gap]. It might be worth an update to your link.”
Step 6: Build the Outreach List and Execute
From the filtered, prioritized data, build a spreadsheet with:
- Target domain and DR
- The specific competitor link they have (URL + anchor)
- The opportunity type (resource page, roundup, guest post, etc.)
- The specific URL on your site you are pitching (match your content to their linked content type)
- Contact email or contact page URL
- Outreach status (not contacted / sent / followed up / won / lost)
The pitch for resource pages and roundups: specific, brief, not about you — about what value you add to their page. “Your resource page on [topic] lists [competitors A, B, C]. I recently published [your page] which covers [specific angle they’re missing] — it might be a useful addition for your readers.” Conversion rates for well-targeted resource page outreach run 5–15%; generic “I have great content” emails run under 1%.

FAQ
What tool is best for competitor backlink analysis?
Ahrefs has the most comprehensive and up-to-date backlink index and the most useful filtering tools (Link Intersect, Best by Links). SEMrush is a strong alternative with comparable data. For a free option, Moz’s Link Explorer provides limited competitor data that is useful for initial analysis before committing to a paid tool. The specific tool matters less than the process: filter, categorize, and prioritize before outreaching.
How often should I run a competitor backlink analysis?
Quarterly is typical for active link building campaigns. Your competitors are continuously earning new links; a quarterly analysis surfaces the newest opportunities (sites that recently added competitors but not you) and tracks whether your link gap is closing or widening. A one-time analysis is useful for building the initial outreach list; recurring analysis is what keeps the pipeline full.
How many competitors should I analyze?
Three to five search competitors for most analysis cycles. More than five produces diminishing returns and creates more data than a small team can action. Focus on the competitors that rank directly above you for your most important keywords — they are the most relevant competitive reference point.
What if competitors have links I can never replicate?
Expect this — every well-established competitor will have links from their early press coverage, founding team networks, and one-off relationships that are not replicable. Filter these out (major news publications, university links, government links that require institutional affiliation) and focus on the 60–70% of their profile that is from sites accessible to outreach. The comparison should be “what is achievable” not “can I replicate their entire profile exactly.”
Should I try to match a competitor’s exact anchor text distribution?
No — build your own natural anchor distribution. Competitor anchor text shows you what anchors are associated with rankings for the topic (useful context) but you should not attempt to replicate their exact distribution. Your profile should reflect natural linking behavior: mostly branded and URL anchors, with keyword anchors appearing organically as content is written about your site. Over-optimizing anchor text to match a competitor is one of the clearest manual over-optimization signals.
