SEO Glossary: 280+ Must-Know SEO Terms

301 Redirect

A 301 redirect is a permanent redirect from one URL to another. It tells search engines that a page has moved for good and passes most of the link equity to the new URL. It’s a key tactic in link building and fixing duplicate content issues.

A 302 redirect is a temporary redirect. Unlike a 301, it doesn’t pass full SEO value, so use it only when the change isn’t permanent.

404 Error

This error occurs when a page can’t be found. It affects user experience and may increase your bounce rate if not handled with a custom error page or proper redirects.

410 Gone

A 410 status code tells search engines that the page is permanently removed and not coming back — more definitive than a 404.
