Crawling & Indexing: a timeline
How search engines find, fetch, render and store pages: crawl budget, robots.txt, sitemaps, canonicals, JavaScript rendering and index coverage. Problems here come before any ranking question — a page that is not crawled and indexed cannot rank, however good it is.

How this is built
Every archived headline is tagged with topics by keyword. Each month shows the most significant crawling & indexing headlines by this site's impact score, plus any Google update that began that month. Months with nothing archived are left out. The archive began in earnest in mid-2025, so earlier months are thin.
