How to use the link gap checker

1

Enter both domains

Your site and a rival who ranks where you want to.

2

See the gap

Every referring domain they have and you don't, sorted by DR.

3

Pitch those sites

They already link to your niche — the warmest targets you'll find.

The smartest way to prospect

Cold outreach fails because most sites have no reason to link to you. A link-gap prospect is different: they've already proven they'll link to your topic by linking to your competitor — relevance and intent baked in.

Higher reply rates — warm, relevant prospects say yes far more often than cold ones.

No guesswork — start from a ranked list instead of hunting for sites to pitch.

Close the gap — every link you win is one your competitor has that you'll now have too.

Link gap FAQ

What is a link gap?
The set of websites that link to a competitor but not to you. Closing the gap means earning those same links — the ones helping them outrank you.
Why target a competitor's backlinks?
Because they've already shown they'll link to a site like yours. That relevance makes them far more likely to say yes than a random cold prospect.
How many competitors can I check?
One at a time for free. Create a free account to compare multiple competitors at once and import opportunities straight into an outreach campaign.
Are spammy domains included?
No. High-spam domains are filtered out automatically, so every opportunity you see is worth pursuing.
