What does Google say about SEO? /
Redirects represent a critical technical component of search engine optimization, especially during site migrations, redesigns, or URL structure changes. This category compiles all official Google statements regarding the implementation of various redirect types (301, 302, 307, 308) and their SEO implications. Understanding Google's stance on redirects is vital for preserving page authority and rankings during structural modifications. SEO practitioners will find valuable insights on PageRank transfer, Googlebot processing timeframes, best practices for avoiding redirect chains, and context-specific recommendations (HTTPS migrations, mobile versions, international content). Google has significantly evolved its redirect handling over the years, notably regarding temporary redirects that can now pass ranking signals under certain conditions. This official documentation enables optimization of migration strategies, minimizes organic traffic loss, and ensures smooth transitions during URL changes while adhering to the search engine's technical guidelines. Whether planning a domain migration, implementing HTTPS, or restructuring site architecture, these authoritative declarations provide the foundation for making informed decisions that protect search visibility and maintain hard-earned rankings throughout technical transformations.

★★ Why does the URL Inspection Tool show a 200 status code even after a redirect?

★★ Are 307 and 308 redirects really pointless for classic SEO?
HTTP codes 307 and 308 also transfer POST requests, unlike 301 and 302 which only transfer GET requests. Useful for APIs but with no direct SEO impact since APIs are generally not indexed....

★★★ Are automatic redirects really killing your international SEO rankings?
