Why check for broken links
Broken links frustrate visitors, leak SEO value, and often point at removed pages or mistyped URLs from the last edit.
- Find dead links before visitors do
- Protect SEO from links to 404s
- Catch mistakes from a recent content edit
- Verify navigation and footer links resolve
- Clean up links to retired pages
