What is the primary purpose of the Link Intersect tool?
Correct: Find domains and pages linking to your competitors, but not to your website.
In the context of the Ahrefs platform, the primary purpose of the Link Intersect tool is to find domains and pages linking to your competitors, but not to your website, which reveals high-probability backlink opportunities that your domain is currently missing. By inputting multiple competing URLs and comparing their backlink profiles against your own, the tool identifies "link gaps"—sites that have demonstrated a willingness to link to others in your specific niche but have not yet linked to you. This is a critical strategy for link building because a website linking to multiple competitors is statistically more likely to be a relevant industry resource or directory where your presence is also expected. Leveraging this data allows SEOs to prioritize outreach to prospects that already have a proven affinity for your topic, significantly increasing the efficiency of a backlink acquisition campaign.
