Link Rot

What is link rot in SEO?

When you link to a web page that no longer exists either because it has been moved without a 301 redirect or the website no longer exists then this is known as link rot – your outbound links have rotted away.

For most small websites this is not a problem, but for large sites like Wikipedia which relies on external sources to verify the information, link rot is a big problem. A study of 550,000 links found that 7% of links pointed to non-existent pages or websites after 5 years.

For SEO analysts, link rot represents an opportunity to build backlinks by emailing the website where you have found broken links and suggesting your resource instead.
