Good SEO work only gets better over time. It's only search engine tricks that need to keep changing when the ranking algorithms change
Jill Whalen
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.
How to Put This Tool to Work for Your Site
The Moz Google Algorithm Update History isn’t just a historical timeline; it’s a vital diagnostic tool.
If your site experiences a significant and unexpected change in organic performance, you can cross-reference the date of the change with this history. If your traffic or rankings dipped or spiked around the same time as a known update (like a Core Update or a Product Reviews Update), you have a strong indication of what caused the shift. This connection is the first, most critical step toward either recovering from a penalty or capitalising on a positive trend. It helps you narrow down your SEO audit, focusing your efforts on the aspects Google was targeting in that specific update, whether it was site quality, link spam, or E-E-A-T (Experience, Expertise, Authoritativeness, and Trustworthiness).
