• Site audits are used to find optimization opportunities, broken links, and technical SEO problems.

• Loss of important SEO knowledge: Blocking SemrushBot prevents you from seeing your website’s data in the tool if you use SEMrush for your website. Semrush cannot track your backlinks, keyword rankings, or technical SEO problems.
• Missed link-building opportunities: SEO depends on backlinks, and Semrush assists in locating linking chances.
