If you’re in the SEO game, you know the search landscape is always changing. Google is constantly tweaking its algorithm, sometimes with small, daily adjustments, and other times with massive, site-shaking core updates. When you see a sudden, inexplicable drop (or even a jump!) in your organic traffic and rankings, the first question on every SEO’s mind is: “Did Google just roll out an update?”

Now, you don’t have to scramble to piece together a timeline.

We want to share a free, indispensable resource from our friends at Moz: the Google Algorithm Update History page. This is a powerful, living document that tracks every major confirmed and unconfirmed Google algorithm update, from the very early days all the way up to the present. It’s a goldmine of information that can provide context and clarity when the SERPs (Search Engine Results Pages) start to get turbulent.
