Backlink Audit
Reviewing links to your site for link spam and breakage; most sites need no disavow.
Reviewed by Alexander Yarovenko · Updated: 2026-10-04
Backlink audit is a review of the links pointing to your site to find those that violate Google’s link spam policy, break, or reveal a pattern you should understand. Its usual outcome is “do nothing”. Google says that in most cases it can assess which links to trust without guidance, so most sites do not need the Disavow tool; it matters mainly when a manual action for unnatural links exists or is likely.
What it is and where the boundary lies
An audit starts from your own data: the Links report in Search Console, which is a sample, not a full list, and does not show nofollow status. Third-party tools add their own indexes and “toxicity” scores. Those scores are the tool’s opinion, not Google data. The audit asks one question about each suspicious link: did we or someone working for us create it to manipulate rankings?
How it differs from similar terms
| Concept | Purpose | Trigger |
|---|---|---|
| Backlink audit | understand and, if needed, clean your links | a manual action, a purchased-link past, a migration, a periodic check |
| Disavow tool | ask Google to ignore listed links | unremovable spam links tied to a manual action |
| Toxic backlinks | an industry label for harmful links | not a Google term |
| Competitor backlink analysis | study rivals’ links | planning content |
| Link reclamation | recover lost or unlinked mentions | broken pages, removed links |
Why it matters
Google’s spam policies name link schemes: buying or selling links for ranking, excessive exchanges, automated link creation and others. If you or an agency created such links, a manual action may follow, and the audit is the first step to fix it. Without that history, an audit mostly protects you from needless anxiety about random low-quality links that Google can handle by itself.
What to do with each finding
| What you found | Action |
|---|---|
| A link you earned or that is simply low quality, no sign of a scheme | leave it; no action is needed |
| A paid or exchanged link that you control | add rel="sponsored" or rel="nofollow", or remove it |
| A scheme link on a site you can contact | ask the owner to remove it or qualify it with nofollow or a more specific attribute |
| A scheme link you cannot get removed, with a manual action or a likely one | list it in a disavow file |
| A broken or lost valuable link | restore the page or ask for a corrected link |
How to apply it
- Export your links from Search Console: the Top linking sites export or the Links report’s latest external links.
- Start with the sites that link most and with links created in the last months, as Google’s manual action guidance suggests.
- Check each suspicious link against the link spam examples; record your reasoning.
- Fix what you control first (your own paid or partner links), then ask owners to remove or qualify the rest.
- Only if a manual action exists or is likely, and removal failed, prepare a disavow file.
- If you have a manual action, submit a reconsideration request after the work, explaining what you did.
Practical example
After removal requests to a spam directory went unanswered and a manual action for unnatural links was open, the file looks like this:
# spam directory, no reply to removal request (2026-10-04)
domain:cheap-links.example
https://blog.example.net/post-with-paid-linkOne entry per line, domain: for a whole host, # for comments. A subpath such as a folder of a site cannot be listed, and the tool does not support Domain properties.
Common mistakes
- Disavowing by a vendor’s toxicity score: Google says most sites do not need the tool, and incorrect use can harm performance.
- Disavowing without trying removal: Google recommends removing links first.
- Treating every low-quality link as a problem: Google says it can usually judge which links to trust.
- Using the tool on a Domain property: the tool does not support it.
- Listing a folder: only single URLs or
domain:entries are accepted. - Counting the Links report as complete: it is a sample and omits nofollow status.
How to validate the result
For a manual action, the check is the Manual actions report and the outcome of your reconsideration request. Without one, record the audit date, the findings and the decision for each group, and re-run after a migration or an agency change. A disavow file is not an instant fix: Google processes it when it recrawls the linking pages, so judge over weeks, not days.
More questions
Do I need to audit regularly?
If you have never bought or traded links, a periodic glance at the Links report is enough. After buying links in the past, or taking over a site from an agency, do a full audit.
Can negative SEO hurt me?
Google says it works hard so that actions on third-party sites do not negatively affect a site, and most sites need no disavow.
Are nofollow and sponsored links a problem?
No. Google says paid links are acceptable when qualified with nofollow or sponsored.
