Frequently asked questions
Common questions about how to use the semrush backlink audit tool.
How long does a backlink audit take?
The duration depends on the number of backlinks your domain has, but most audits complete within a few minutes to several hours. Semrush will notify you when the audit is finished and your report is ready for review.
What makes a backlink toxic or low-quality?
Semrush evaluates backlinks based on factors like domain authority, relevance, spam score, and anchor text quality. Links from low-authority sites, unrelated niches, or known spam sources are typically flagged as problematic.
Should I disavow all flagged backlinks?
Not necessarily. Review each flagged link individually before disavowing, as some may still be valuable. Focus on disavowing links that are clearly irrelevant, spammy, or from low-quality sources that could harm your rankings.
How often should I run a backlink audit?
It's recommended to run audits at least quarterly or whenever you notice changes in your search rankings. Regular audits help you catch new toxic backlinks early and maintain a healthy backlink profile.
What's the benefit of connecting Google Search Console?
Connecting Google Search Console allows Semrush to correlate your backlink data with actual search performance metrics like impressions and clicks. This helps you understand which backlinks are actually driving value to your site.
