Frequently Asked Questions
What is the SEO difference between a 301 and a 302 redirect?
A 301 Moved Permanently tells search engines to transfer 100% of the original page's PageRank link equity to the new destination URL, whereas a 302 Found instructs crawlers that the move is temporary and to retain the original URL in the index.
How does Google treat a 410 Gone compared to a 404 Not Found?
A 410 Gone explicitly tells Googlebot that the page was intentionally removed permanently, purging it from the index significantly faster than a 404 which Googlebot will re-check multiple times.
