Google Search: Algorithm Updates, Search Console and Ranking Changes

Google Search changes constantly, and most of those changes are never announced. Core updates, ranking system changes, new search features and changes to Google Search Console (Google’s free reporting tool for site owners) can shift traffic for an entire site overnight. Separating a real algorithm change from a tracking problem or a technical issue on the site itself is the first step in any traffic analysis.

This hub gathers my coverage of Google Search over the years: Panda and Penguin, PageRank and link signals, Search Console features as they were added and removed, indexing and crawling issues, and the reporting gaps that make Google’s own data harder to read. The posts below are written from the perspective of someone who has diagnosed traffic drops for more than two decades, so they focus on what changed, how to verify it and what a site owner should actually do about it.
