Common SEO mistakes to avoid include duplicate content, slow page speeds, poor mobile optimization, and weak keyword research that prevent your website from ranking well in search results.

These mistakes affect most websites and can significantly hurt your search visibility, but they're fixable once you know what to look for.

Additional SEO mistakes to avoid:

Semrush's Site Audit can help identify and prioritize these technical issues, while Position Tracking monitors your progress as you fix them.
