Why Fix Broken Links?

Broken links negatively impact your website's SEO ranking and user experience. Search engines like Google penalize sites with numerous broken links, viewing them as poorly maintained.

SEO Impact: Broken links waste crawl budget and reduce page authority
User Experience: Dead ends frustrate visitors and increase bounce rates
Credibility: Broken links make your site appear unprofessional and outdated
Lost Traffic: Broken internal links prevent proper site navigation

Pro tip: After fixing broken links, use tools like SitemapForge to further optimize your site's performance.
