This guide describes how to optimize Google's crawling of very large and frequently updated sites.

If your site does not have a large number of pages that change rapidly, or if your pages seem to be crawled the same day that they are published, you don't need to read this guide; merely keeping your sitemap up to date and checking your index coverage regularly is adequate.

If you have content that's been available for a while but has never been indexed, this is a different problem; use the URL Inspection tool instead to find out why your page isn't being indexed.
