Definition
Link gap analysis is a strategic link building technique that involves comparing your backlink profile with that of your competitors to identify domains linking to them but not to you. This analysis reveals concrete link acquisition opportunities because if a site already links to a competitor in your niche, there is a strong chance it would be open to linking to your site as well. The method involves: selecting 3 to 5 direct competitors, extracting their backlink profiles via tools like Ahrefs, SEMrush, or Majestic, identifying domains common to multiple competitors but absent from your profile, then prioritizing opportunities by authority and topical relevance. Link gap analysis is particularly effective because it targets sites already inclined to link within your industry, thus increasing the success rate of outreach campaigns.
Key Points
- Compares your link profile with competitors to find opportunities
- Targets sites already inclined to link within your industry
- Main tools: Ahrefs Link Intersect, SEMrush Backlink Gap, Majestic
Practical Examples
Analysis with Ahrefs
Use the Ahrefs 'Link Intersect' tool by entering your domain and 3 competitors. The tool reveals domains linking to at least 2 competitors but not to you: these are your best opportunities.
Opportunity prioritization
After identifying 200 domains via link gap analysis, filter by DR > 30, topical relevance, and content type (articles, directories, resources) to prioritize the 50 best outreach targets.
Frequently Asked Questions
Ideally 3 to 5 direct competitors ranking for your target keywords. Too few will not reveal enough opportunities, too many will dilute results. Prioritize competitors that outrank you on your priority queries.
Conduct a complete analysis quarterly and monthly checks on your main competitors. The backlink landscape evolves constantly and new opportunities appear regularly.
