Backlink Audit
A full backlink audit for your domain, free with every project: your Authority Score and its history, every backlink with its anchor and status, toxic link detection, new and lost links synced daily — and a ready-to-upload disavow file when the clean-up calls for it.
Your whole link profile, organised
The audit is split into focused views: an Overview with the headline numbers and trends, every individual backlink, Referring Domains, Anchors, the Target Pages on your site that links point at, a Network view of where your links come from, and Lost & Found for movement. Each backlink carries its anchor text, dofollow status, the linking domain's authority, and first/last seen dates.
Authority Score, with history
Your domain's Authority Score (0–100) sits at the top — the same style of strength metric the paid suites charge for — with monthly history going back up to five years, so you can see whether your profile is compounding or stalling. Backlink and referring-domain counts get the same treatment: click any headline number and the trend opens.
Toxic link detection
Every link and referring domain has a toxicity score from 0–100: 60 and above is flagged toxic, 30–59 potentially toxic, the rest clean. The Audit view groups your profile into those three buckets so you can work through the risky end methodically — and a weekly snapshot builds a toxicity-over-time chart, so you can prove the clean-up is working.
From audit to disavow, in one flow
Reviewing a bad neighbourhood of links? Mark domains or individual links for removal (the ones you'll chase by email) or disavow (the ones you won't), and whitelist false positives so they stay out of your way. When you're done, download the generated disavow.txt — correctly formatted for Google's disavow tool, no hand-editing.
New and lost links, every day
After the initial backfill, a daily sync picks up what changed: links you gained and links that vanished. Lost links from strong domains are the cheapest wins in link building — the page moved or the link broke, and a polite email often gets it back. Lost & Found puts them in one queue.
How to audit your backlinks
1. Add your site as a project
The initial backfill pulls in your profile; the daily sync keeps it moving from then on.
2. Work the audit
Start with the toxic bucket: whitelist anything that's actually fine, mark genuine spam for removal or disavow.
3. Export the disavow file
Download the generated disavow.txt and upload it in Google Search Console's disavow tool.
Frequently asked questions
What does the backlink audit show?
Your domain's full link profile: Authority Score with history, every backlink with its anchor, dofollow status and first/last seen dates, referring domains, anchor-text breakdown, the pages on your site links point at, and which links are new or lost — refreshed daily.
What is the Authority Score?
A 0–100 strength score for a domain's backlink profile, comparable to the authority metrics in paid suites. You get your score, its monthly history going back up to five years, and the score of every referring domain.
How do you detect toxic backlinks?
Every link and referring domain carries a 0–100 toxicity score; 60+ is flagged toxic and 30–59 potentially toxic. The audit view groups your profile into clean, potentially toxic and toxic — and tracks how that mix changes week by week.
Can it generate a disavow file?
Yes. Mark domains or links for disavow as you review them and download a correctly formatted disavow.txt, ready to upload to Google's disavow tool. There's also a remove list for links you plan to chase down manually, and a whitelist for false positives.
How do I see new and lost backlinks?
The Lost & Found tab tracks both: links you've gained and links that disappeared, synced daily. Lost links from strong domains are often recoverable — a polite email beats building a new link from scratch.
How fresh is the data?
Your profile gets an initial backfill when you add the project, then a daily sync picks up new and lost links. Trend snapshots build the history charts automatically.
Can I check a competitor's backlinks?
The audit runs on your project's own domain — it's a monitoring and clean-up tool rather than a prospecting database. For competitor research, the AI Keyword Overview shows the backlink strength of every page ranking in the top 10 for any keyword.
Is the backlink audit free?
Yes — the full audit, including toxicity scoring and the disavow generator, is included free with every RankNibbler project.
