Google is constantly working to improve its search results in conjunction with ensuring users get access to quality online content. 

In one recent year, Google made 4,800 improvements in the search process. The search engine giant’s algorithms are ever-evolving, but one evergreen constant is that content needs to meet high standards set by Google. 

One of the factors that Google hopes site owners will pay attention to is the E.A.T. Google algorithm.

It’s a little funny, if you think about it: Google tosses out a few thousand tweaks to the algorithm every year—4,800 in 2025, which isn’t exactly a small number—and expects everyone to keep pace. Most people don’t notice the smaller updates, of course. But when something like E.A.T. comes along, suddenly it feels like there’s a spotlight shining on every sentence you publish. You start to wonder if the “E” in E.A.T. stands for “Endless rewriting.”

Sit back and get comfortable because the information about E.A.T. is contained in a 170-page volume called the “Search Quality Rater Guidelines”. 

The E.A.T. acronym stands for Expertise, Authoritativeness, and Trustworthiness. It isn’t some secret recipe or underground hack; it’s a set of expectations that reflects what any decent reader is already looking for—honest expertise, a source that knows its stuff, and a sense that you’re not being taken for a ride. It’s a little dry when you read it off the page, but in practice it’s just, write content you’d actually want your friend to read and believe. If your site deals with topics like health or money, well, the scrutiny gets dialed up another notch because the stakes are higher. Makes sense, right?

Together, we’ll pore over this document, word by word, to find out everything you need to know about the E.A.T. Google algorithm.

Just kidding.

We’ve done the heavy lifting for you, so this will be an easy-to-digest rundown that gives you all the information you need to know about E.A.T.
