What is genuinely scarce is a timeline that gets the classifications right. Most published lists put &#8220;Medic,&#8221; &#8220;Fred,&#8221; &#8220;Phantom,&#8221; and the March 2024 core update in the same column, as though they were the same kind of event. They aren&#8217;t. Two of those are nicknames the SEO industry invented for ranking volatility it noticed but Google never named. One is a documented, dated, officially announced rollout with a published start and end. Treating them as equivalent is how teams end up rewriting content to recover from an &#8220;update&#8221; that was actually a manual policy enforcement action, or waiting out a &#8220;core update&#8221; that was really an indexing infrastructure change. This guide separates them. It covers the named Google algorithm updates from Boston in February 2003 through the August 2026 spam update, sorted into seven classes, with rollout durations for the modern confirmed era. It also does something the standard timeline doesn&#8217;t: it analyses the rollout data itself, because how long an update takes to deploy is a diagnostic signal most SEOs never use. What counts as a Google algorithm update \u2014 and what doesn&#8217;t Before any timeline is useful, you need [&hellip;]","thumbnail_url":"https:\/\/4goodhosting.com\/blog\/wp-content\/uploads\/2026\/08\/ChatGPT-Image-Aug-29-2026-02_24_50-AM.webp","thumbnail_width":1672,"thumbnail_height":941}
