A backlink audit answers one question: which links help, which do nothing, and which might cause trouble? It is not a hunt for a magic number. This walkthrough shows a workflow you can run in an afternoon on a typical site, with notes on where it gets uncertain. For the wider picture of ongoing work, see our hub on Backlink Monitoring & Analysis.
Before You Start: Set the Scope
Decide what you are auditing. A whole domain, a single section, or the pages that drive revenue each need a different depth. Write down your goal: a routine health check, a post-migration review, a traffic drop investigation, or a pre-outreach baseline. The goal decides how much detail you need.
- Pick a date and save your exports. Link data changes constantly, and you will want a baseline to compare against later.
- Know the vocabulary. If the difference between links and linking sites is fuzzy, read backlinks vs referring domains first.
Step 1: Collect Data From More Than One Source
No single index sees the whole web. Each tool crawls differently, so exports overlap but never match. Pull from at least two sources where you can:
- Google Search Console (the Links report), which is free and shows links Google has chosen to report to you.
- One third-party backlink tool, free or paid.
If budget is tight, checking who links to your site for free is a workable starting point. Free sources are usually sampled or capped, so treat the result as a partial view. Confirm current limits on each tool's official site, because they change.
Merge the exports into one spreadsheet and deduplicate by linking URL and target URL.
Step 2: Get the Big Picture
Before opening individual links, look at the shape of the profile.
- Referring domains vs total links. A large link count from few domains often means sitewide links (footers, blogrolls) rather than broad endorsement.
- Growth over time. Steady growth looks different from sudden spikes. Spikes can be a good press hit or a spam run; you have to check.
- Top linked pages. Are links going to useful content, or mostly to the homepage?
Whether your domain count is healthy depends on your niche and competitors, so see how many referring domains is a good number for how to benchmark sensibly. For help interpreting the columns in your export, our guide to reading backlink metrics covers it.
Step 3: Review Link Quality
Check the linking sites
Sort by referring domain and skim the list. You are looking for relevance, a real audience, and editorial context. Authority scores from tools are estimates built on each vendor's own method. Use them to sort, not to judge.
Check the links themselves
Open a sample of links, especially the ones that stand out. Note whether the link sits in body content, a sidebar, a comment, or a directory page. Check the attribute too: dofollow and nofollow links behave differently, but a healthy profile normally contains both.
Check anchor text
Look for repeated exact-match commercial anchors, which can look manipulative. Branded, URL, and generic anchors are normal. The full method is in how to analyze anchor text patterns.

Build a simple sheet with three labels: keep, watch, and investigate. Common warning signs include:
- Clusters of links from unrelated, thin, or auto-generated sites.
- Sudden bursts of links with near-identical anchors.
- Links from pages in languages or topics with no connection to you.
- Paid or exchanged links that are not marked up appropriately.
Honest trade-off: one odd-looking link is not evidence of a problem. Every site collects junk, and search engines are generally built to ignore much of it. Be cautious about aggressive cleanup based on a score alone.
Broken and lost links
Links pointing to pages that return errors waste value you have already earned. Learn to find broken backlinks and redirect or restore the target where it makes sense. For links that disappeared entirely, tracking new and lost backlinks explains how to decide which are worth recovering.
Step 5: Decide What to Do
| Finding | Typical action | Trade-off |
|---|---|---|
| Good links to broken pages | Redirect or restore content | Needs a relevant destination |
| Lost quality links | Contact the site owner | Time-consuming; no guarantee of reply |
| Obvious spam pattern | Document it; consider Google's disavow tool as a last resort | Misuse can remove helpful links; Google describes it as advanced |
| Thin profile | Create content worth citing, then do outreach | Slow, results uncertain |
If you suspect a manual action, check the Manual Actions report in Search Console first. Disavowing is rarely needed without one.
Step 6: Set a Rhythm and Report
Data lags. A new link can take a while to appear in tools, as explained in how long new backlinks take to show up, so do not panic over a missing link on day two. For frequency, see how often to check your backlinks; monthly is a reasonable default for many sites, with a deeper audit once or twice a year.
If you answer to others, keep the report simple: new and lost domains, notable wins, issues found, and next actions. Our guide on reporting backlink progress has a structure to borrow.
Choosing a Tool
Free sources are enough for small sites, while larger sites usually benefit from a tool with bigger indexes, alerts, and history. Features and pricing vary and change, so compare options on our review and comparison pages and confirm current details on each vendor's official site before you commit.
What an Audit Can't Tell You
An audit describes the past and present of your links. It cannot predict rankings, and fixing issues does not guarantee improvement. Treat it as maintenance and a way to spot opportunities, not a switch you flip.
