Everyday expertise is real in the guidelines — and routinely ignored by SEOs

The question: does the Quality Rater Guidelines require formal credentials for expertise, or does it recognize informal expertise?

It explicitly recognizes informal, 'everyday' expertise. Per the QRG, for many topics the relevant expertise comes from life experience, not certification. Someone who has managed a chronic condition for a decade has expertise about living with it. A person who has restored dozens of a particular car model has expertise about that model. The guidelines name this directly and tell raters not to dismiss it for lack of formal credentials.

The crucial boundary: the guidelines also distinguish where everyday expertise suffices from where it does not. For experiential and practical topics, lived expertise is appropriate and sometimes superior. For medical, legal, financial, and safety advice — the high-harm end of YMYL — formal expertise is required, and everyday experience can be insufficient or dangerous. The dosing example: a patient's experience is valuable for what living with treatment feels like; it is not a substitute for clinical expertise on what dose is safe.

The practical error this corrects: forcing credentialed-expert framing onto content where lived experience is the more trustworthy source. A first-person account of recovery does not become more trustworthy by appending an MD byline who never had the condition.

Counter-evidence and caveat: this is rater nuance that systems likely approximate crudely. A classifier cannot easily tell everyday expertise from naive opinion, and probably errs toward credential proxies it can detect.

What we still don't know: how systems distinguish authentic everyday expertise from confident amateurism — the same detection problem that haunts the experience signal, in a different costume.
