Repair Windows errors before they cause bigger problemsFix Now →Fix the driver behind crashes, sound loss and screen glitchesFind Drivers →For finding websites that link to competitors but not to you, start by comparing Ahrefs Link Intersect and Semrush Backlink Gap. Both vendors document a competitor link-gap workflow. Majestic Site Explorer is another backlink-analysis option, but its cited overview does not establish an equivalent gap-finding feature. These are feature comparisons, not independent tests of database accuracy: the available documentation does not prove that their backlink indexes are directly comparable.
Which backlink tools document competitor link-gap analysis?
A link-gap report helps identify referring domains—or, in some workflows, individual pages—that link to competing sites but not to your own. That makes it useful for prospecting: you can investigate whether those sites might also be relevant sources for your content or outreach. A report is a lead list, not proof that a link is obtainable or that pursuing it will improve rankings.
| Tool | What its official documentation supports | What to verify before choosing |
|---|---|---|
| Ahrefs Link Intersect | Compare a target with competitor domains or pages to find referring domains or pages linking to competitors but not the target. Ahrefs documents adding up to 10 competitors, filtering results, and exporting intersecting domains or backlinks. Ahrefs workflow guide; Ahrefs Help Center. | Whether the domain-level or page-level view, filters, and export workflow suit your task; confirm current account limits. |
| Semrush Backlink Gap and Backlinks | Backlink Gap compares profiles to surface domains linking to competitors but not the target. Semrush also documents quick comparison, referring-IP and anchor-text analysis, and competitor top-performing-page insights in its Backlinks tool. Backlink analysis and link-building tools; Semrush Knowledge Base. | How the gap report and broader backlink analysis fit your workflow; verify current plan access and export limits. |
| Majestic Site Explorer | Majestic describes Site Explorer as a suite of backlink-analysis reports for a website or page. The cited overview does not establish a matching competitor-gap workflow. Majestic Site Explorer overview. | Check whether its available reports support your specific competitor comparison; do not assume a gap feature based on the overview alone. |
When Ahrefs Link Intersect is a fit
Ahrefs documents comparing a target with competitors to find referring domains or pages that link to those competitors but not the target. Its help materials describe adding up to 10 competitor URLs or domains, filtering the results, and exporting intersecting referring domains or backlinks. See the Link Intersect guide and the export instructions.
This is a straightforward choice to evaluate when you want to build a competitor-based prospect list and need to inspect or export the results. Decide whether you want to pursue whole referring domains or investigate individual linking pages; those answer different questions. The documented competitor count is a workflow capability, not a guarantee about what a particular subscription currently allows, so check access and quotas for the plan you would use.

When Semrush Backlink Gap is a fit
Semrush describes Backlink Gap as a way to compare backlink profiles and find domains linking to competitors but not the target. Its Backlink Gap overview explains the gap-finding purpose, while the Backlinks tool documentation describes quick comparisons, referring-IP and anchor-text analysis, and competitor top-performing-page insights.
Consider it if you want the gap report alongside broader backlink inspection. The cited feature descriptions do not establish current plan-by-plan access, export quotas, or how Semrush’s database performs relative to another vendor’s. Confirm the capabilities you need in the current product and plan before committing.
What Majestic Site Explorer does—and what is not established
Majestic’s Site Explorer overview supports evaluating it for backlink analysis centered on a website or page. The cited page does not demonstrate a competitor link-gap workflow comparable to Ahrefs Link Intersect or Semrush Backlink Gap. If discovering domains competitors have that you lack is essential, verify that exact workflow before treating Majestic as a direct substitute.
How to choose a tool for your comparison
- Define the question. Decide whether you need domains competitors have that you lack, the individual pages producing links, or a broader backlink-profile audit.
- Check the comparison inputs. Look at how many competitors you can include, whether you can compare domains and pages, and how the report treats the target.
- Test the investigation workflow. Check whether filters, anchor-text or referring-IP analysis, and competitor-page insights help you judge each result’s relevance.
- Confirm how you can use the output. Verify exports, quotas, and plan access for the account you would actually buy. Current comparable subscription prices and limits are not established by the cited feature documentation; check vendors directly before comparing value.
- Validate prospects yourself. Review the linking page and site before outreach. A tool’s report identifies potential opportunities; it does not establish editorial fit or guarantee a link.
Why backlink counts and rankings should not decide the winner
The cited sources describe product features and workflows, not an independent, apples-to-apples measurement of index completeness or accuracy. Differences between two reports should therefore be treated as differences in the vendors’ reported data, not proof that one tool has found every link or is objectively more accurate. No supported performance statistic or current, comparable value ranking is established here.
