On the next search query - **it searches not the internet, but its own index**. --- ### Why this matters: As long as a page **is not indexed**, it **cannot appear in the results**. A site may exist but be "invisible" to Google. --- ### What affects indexing: - The presence of a link to the page (internal or external) - robots.txt and the `noindex` meta tag - Site loading speed and availability - Structure and sitemap (sitemap.xml) - Duplicate content --- **Conclusion:** Indexing is like adding a book to a library catalog. Until it's there, no one will find it.For the reviewerNote to the moderator (optional)Visible only to the moderator. Helps review go faster.
