How Redirects Affect SEO
Redirects are essential for maintaining website health, especially when deleting pages, changing URL structures, or migrating to a new domain. However, when implemented poorly, they can completely destroy your search engine rankings and severely degrade user experience.
301 vs. 302 Redirects
Understanding the HTTP status code returned by your server is critical:
- 301 Moved Permanently: This is the only redirect you should use for SEO. It tells Google that the page has permanently moved, passing approximately 90-99% of the original page's link equity (PageRank) to the new destination.
- 302 Found (Temporary): This tells Google the move is temporary. It does not reliably pass link equity. Use this only for temporary promotions or site maintenance.
The Danger of Redirect Chains
A redirect chain occurs when there is more than one redirect between the initial URL and the final destination (e.g., Page A → Page B → Page C). Why is this bad?
- Loss of Link Equity: Google dilutes link equity with every "hop" in a chain. A chain of 3 or 4 redirects might result in zero authority being passed to the final page.
- Crawl Budget Waste: Googlebot will eventually give up if a chain is too long (typically after 5 hops), meaning your final page might never get indexed.
- Slower Page Speed: Each redirect requires a new DNS lookup and server request. On mobile networks, a long redirect chain can add seconds to the load time. Check your speed impact using our Core Web Vitals Tool.
HTTP to HTTPS Redirects
A common mistake is linking to the http:// version of your site, which then redirects to https://, which then redirects to the www version. Ensure all internal links and sitemaps point directly to the final, secure URL. Verify your SSL configuration with our SSL Checker Tool.
