301 301 Moved Permanently
The resource has been permanently moved to a new URL. Browsers and crawlers should update their references.
When you'll see it
When a URL has moved for good: a renamed page, a move from HTTP to HTTPS, or a move to a new domain.
What to check
- That the redirect goes straight to the final URL. Chains of several hops waste crawling and slow visitors down.
- That the target answers 200 and is the closest match, not just the home page.
- That internal links and the sitemap point to the new URL, so the redirect is only a safety net.
- That it's really permanent, since browsers can cache a 301 for a long time.
