What does Google say about SEO? /
The Crawl & Indexing category compiles all official Google statements regarding how Googlebot discovers, crawls, and indexes web pages. These fundamental processes determine which pages from your website will be included in Google's index and potentially appear in search results.

Google's official positions on these topics are essential for SEO professionals as they help avoid technical blocking issues, accelerate new content indexation, and prevent unintentional deindexing. Understanding Google's crawling and indexing processes forms the foundation of any effective search engine optimization strategy, directly impacting organic visibility and SERP performance. Whether troubleshooting indexation problems, optimizing crawl efficiency for large websites, or ensuring proper URL canonicalization, these official guidelines provide authoritative answers to complex technical SEO questions that shape modern web presence and discoverability.
