Frequently Asked Questions

What does HTTP 301 mean?

301 Moved Permanently: the URL has permanently moved to a new location. Browsers and search engines follow and update the new URL.

What causes a 404 error?

404 Not Found: the server cannot find the requested URL. Common causes: deleted pages, mistyped paths, or incorrect internal links.

What is the difference between 301 and 302?

301 is permanent (SEO equity passes). 302 is temporary (SEO equity stays at original URL). Use 301 for all permanent changes.
