- A robots.txt file controls which URLs a crawler may access; it does not by itself prove that a URL was crawled, indexed, ranked, or shown in search results. informative
- A sitemap helps Google discover new and updated URLs, but Google documents sitemaps as suggestions rather than guarantees that every submitted URL will be crawled or crawled immediately. informative
- Meeting Google Search technical requirements and best practices does not guarantee that Google will crawl, index, or serve the content. informative
- A page may be crawled yet still not appear in search results when Google determines that the page lacks sufficient value or user demand; serving must therefore be measured separately from crawl evidence. informative
