What this tool does
A backlink gap (or link intersect) analysis reveals the sites that already link to your competitors but haven't linked to you yet. Those sites are proven to link out in your niche, so they're some of the warmest, highest-probability outreach targets you can find. This tool compares your referring domains against one or two competitors' and surfaces exactly which domains you're missing.
How to use it
It is instant:
- Export each competitor's referring domains from any backlink tool.
- Paste them into the competitor boxes, and your own domains in the last box.
- Click Find link gaps.
- Get the list of domains that link to competitors but not you — then reach out.
Why the gap matters
Sites that link to multiple competitors are the strongest signals of all — if a domain links to two rivals but not you, it clearly covers your topic, links out editorially, and is missing your brand. Prioritising those "links to both competitors" domains gives you a focused, high-conversion prospect list instead of cold, random outreach. The tool flags which competitors each gap domain links to so you can sort by strength.
No API needed — you supply the data
Most backlink-gap tools require an expensive subscription. This one works with data you already have: export referring domains from Google Search Console (for your own site) and from any backlink tool's competitor report, then paste them in. Everything is compared locally, so there's no API key, no limits, and no cost — just the intersect logic done instantly in your browser.
Turning gaps into links
Once you have your gap list, qualify each domain for relevance and authority, then pitch. Because these sites already link to competitors, a well-targeted email — "you featured X and Y, here's why we belong too" — converts far better than cold outreach. Use our Backlink Outreach Email Templates for the pitch and our Domain Authority Checker to prioritise the strongest targets.
Privacy
The comparison runs entirely in your browser — your domain lists are never uploaded, logged, or stored. You can analyse competitor data privately without any of it leaving your device.
