E-E-A-T: The Extra E Was for 'Experience' (How Convenient)

Written in 2026, looking back at the extra E in E-E-A-T, which I now think was the quietest important thing Google did all decade.

In December 2022, weeks after ChatGPT arrived and the whole industry started sweating about AI-written everything, Google updated its quality-rater guidelines and added a letter. E-A-T, the old shorthand for Expertise, Authoritativeness and Trust, became E-E-A-T. The new E stood for Experience. First-hand experience. Whether the person who made this content had actually done or used or lived the thing they were writing about.

The timing was so tidy it was almost a wink. I sat with it properly in the spring of 2023, and the more I looked, the more it read as the single most important sentence Google would write for years, hidden inside a document almost nobody outside the industry reads.

The convenient coincidence

Let me say the obvious thing plainly. Right as machines became able to generate infinite fluent, expert-sounding, authoritative-sounding, trustworthy-sounding text, Google added the one quality a machine cannot generate: having actually been there.

Expertise can be imitated. A model can sound like a doctor. Authoritativeness can be imitated, a model can produce a page that carries itself like a definitive source. Trust is shakier but even trust signals can be gamed. Experience is the one that breaks the imitation. You cannot have used a product you have never touched. You cannot describe the specific way a thing failed on you at 3am if it never failed on you, because it never happened to you at all. Experience is the watermark reality leaves on content, and it’s the one thing that doesn’t come out of a prompt.

I don’t think that letter was an accident of timing. I think Google looked at what was coming, a web about to fill with generated text, and asked what quality could still tell the real from the synthetic. The answer was: did a human actually do this. So they wrote it into the guidelines and let it sit there, quietly, waiting to matter.

Why this is basically everything I now believe

I’ll be honest that in April 2023 I noted the change, filed it as interesting, and didn’t yet grasp that it was the thesis. It took getting hit, watching traffic move, watching the Reddit shift, watching the AI answers reach for lived sources, before the single letter clicked into place as the thing connecting all of it.

Every wave since has rewarded the same quality. The Helpful Content Update went hunting for pages with no real experience behind them and found plenty of mine. The forum surge was Google reaching for the most first-hand corner of the web it had. The AI answers, when they need a source to trust, reach for content that reads as genuinely lived. It is all the extra E, playing out at scale, over and over.

So if I had to compress everything I’ve learned since 2022 into one instruction, it would be: make the thing only you could make, because you were actually there. That is not a clever strategy. It’s just the extra E, taken seriously.

The uncomfortable flip side

Here’s what it also means, and I don’t love saying it. Most of the content the SEO industry taught itself to produce, and that I produced too, was heavy on expertise and authority signals and light on actual experience. We got very good at sounding like we’d done things. The machines can now sound like they’ve done things for free, instantly, forever.

Which leaves exactly one moat, and it’s not a technique. It’s whether you actually did the thing. I find that oddly reassuring. After years of chasing signals and tricks, the durable advice turned out to be go and have real experiences and write from them. Google added one letter in late 2022 to tell us so. It took me most of 2023 to properly listen.
