What does Google say about SEO? /
Domain names represent a foundational element of any SEO strategy, and Google's official statements on this topic provide essential clarifications for search engine optimization professionals. This category compiles all of Google's positions regarding the impact of domain choices on rankings: the influence of extensions (generic vs geographic TLDs), the use of subdomains versus subdirectories, the relevance of exact match domains (EMD), and technical questions related to URL structures. Google has regularly clarified its stance on these aspects, particularly concerning the relative importance of domain names in the ranking algorithm. Understanding these declarations helps dispel persistent misconceptions, such as overvaluing keywords in domains or myths surrounding certain extensions. Official recommendations also cover domain migrations, the use of the www prefix, trailing slash management, and optimal URL architecture. For SEO experts, this information proves crucial when launching new projects, undertaking redesigns, or developing international strategies, enabling informed decisions based on verified facts rather than assumptions. These insights directly impact technical SEO implementation and help align domain strategy with Google's actual ranking factors and best practices for sustainable organic visibility.

★★★ Can a ccTLD Really Serve as a Global Domain Without Penalizing International SEO?
