Experience vs Expertise: What's the Difference in E-E-A-T?

Expertise is the level of knowledge and skill a content creator has in a subject - formal training, credentials, or deep, demonstrated command of the subject matter, the kind of authority a doctor or lawyer brings to a topic in their field.

Experience is first-hand, lived contact with the specific situation being written about - not necessarily formal knowledge, but having actually gone through it: what the process felt like, what the details looked like in practice, details someone without that direct contact simply couldn't know.

Google added Experience as its own distinct signal to the E-E-A-T framework in December 2022, specifically to separate content written by someone who has genuinely lived through a topic from content that only sounds authoritative because it's been assembled from other sources without any first-hand contact behind it. The clearest way to see the distinction is a single example used often in Google's own guidance: a doctor can offer scientific, credentialed knowledge about a medical treatment - that's expertise - while a patient who actually underwent that same treatment can describe what the recovery genuinely felt like, details a textbook doesn't cover - that's experience, with no formal medical credential required for it to be valuable. Neither quality substitutes for the other, and the strongest content on a topic often combines both: credentialed expertise establishing that the information is accurate, and genuine first-hand experience establishing that it reflects what the situation is actually like to go through.
