What the Backlink Gap Analyzer does
The hardest question in link building isn’t "how do I get links" — it’s "which sites would plausibly link to me?" A backlink gap analysis answers it with evidence: sites already linking to your competitors have demonstrated they link out to content like yours. This tool compares your domain against up to 10 competitors and exports every gap domain to CSV or Excel.
Domains linking to two or three competitors are the priority tier — they link to your content category repeatedly, which makes them the warmest possible outreach targets. Vet each prospect’s quality with the Domain Authority Checker before spending outreach effort, and pair this with the Keyword Gap Analysis to close both gaps at once.
How to use it
- Pick competitors in your authority range, not giants: Comparing against sites your size produces a gap list you can realistically earn; comparing against major brands produces links you never will.
- Enter your domain plus up to 10 competitors: More competitors surface more shared linkers, but keep them genuinely comparable so the overlap actually means something.
- Prioritize domains linking to two or three competitors: A site that links to several of your rivals is a proven, repeat linker in your niche and your warmest outreach target.
- Qualify every prospect before you pitch: Run each gap domain through the Domain Authority and Spam Score checkers, and drop directories and scraped-content sites before spending outreach effort.
- Match your pitch to the link’s format: Look at how each domain linked to a competitor, whether guest post, resource page, or data citation, and offer something of the same shape.
Backlinks and rankings by the numbers
A link gap matters because links still track rankings closely, and most of the web has almost none. These figures frame the opportunity.
| Finding | Figure | What it means |
|---|---|---|
| Pages with zero referring domains | ~66% | Ahrefs. Most of the web is unlinked, so even a handful of quality links moves you ahead of the field. |
| Referring domains vs rankings | Strong correlation | Ahrefs and others repeatedly find top-ranking pages have more linking domains than lower ones. |
| Pages with zero Google traffic | 96.55% | Ahrefs. Content without links or demand rarely ranks; closing the link gap is a direct lever. |

Backlink Gap Analyzer FAQ
Why is a gap analysis better than cold link prospecting?
Because every domain in the gap list has already linked to content like yours — they’re proven linkers in your topic. Response rates on outreach to gap domains run far higher than cold prospecting from scratch.
Which competitors should I compare against?
Sites that rank for your target keywords with authority in your range. Comparing against giant brands produces a gap list full of links you can’t realistically earn; peers produce an actionable one.
What do I do with the gap list?
Qualify it first — check authority and spam scores, drop directories and scraped-content sites. Then look at what format earned each link (guest post, resource page, data citation) and pitch something of the same shape.
