The technical signals get you readable. Authority is what gets you trusted. An engine deciding whether to cite you is, in effect, asking “is this a source I can stand behind?” Your job is to make the answer an easy yes. That also means cutting through the noise on a term you have probably heard misused: E-E-A-T.
What E-E-A-T actually is
E-E-A-T stands for Experience, Expertise, Authoritativeness, and Trust. Google added the first E, Experience, in December 2022, to ask whether content was created with genuine first-hand experience. Trust sits at the center; in Google’s own words, it “is the most important member of the E-E-A-T family,” because an untrustworthy page is low quality no matter how expert it looks.
Most people get this part wrong. E-E-A-T is not a ranking factor, and there is no “E-E-A-T score.” Google’s own documentation says E-E-A-T “isn’t a specific ranking factor,” and its search liaison stated plainly in 2024 that no such score exists. It is a framework Google’s human quality raters use to describe what good content looks like. So treat E-E-A-T as a north star for how to come across, not a setting you can optimize directly.
It still matters for AI, just indirectly. Google says its AI features are “rooted in our core Search ranking and quality systems,” and that optimizing for AI search “is still SEO.” So the same qualities those raters describe carry through to AI answers on Google’s surfaces. What no vendor (Google, OpenAI, Perplexity) publishes is a rule that says “we cite sources with high E-E-A-T.” Anyone who tells you otherwise is guessing.
The useful test: Who, How, Why
Google’s helpful content guidance gives a far more useful test than the acronym: evaluate your content on Who, How, and Why.
- Who made it? Is it obvious to a reader who wrote this? Real bylines, with author names that lead to genuine background and credentials. Anonymous content is harder to trust, for people and for engines.
- How was it made? Be transparent about your process. If a page is a review, show that you actually tested the thing. If you used AI to help produce content, the guidance is to be open about it.
- Why does it exist? The answer should be “to help the reader,” not “to rank.” Content built primarily to game search is exactly what these systems are built to discount.
Concretely, that means: original information rather than rehashed summaries, clear sourcing and evidence, named experts who demonstrably know the topic, and the kind of page a reader would want to bookmark or send to a friend.
Entity authority: be a recognized thing
Beyond any single page, engines try to understand you as an entity, a specific organization they can recognize and connect to what else the web says about you. Two parts of this are well documented:
- Search engines maintain a knowledge graph of entities, and public sources like Wikidata and Wikipedia feed into it.
- The
sameAsproperty in your structured data is the documented way to link your site to your authoritative profiles, your LinkedIn, Crunchbase, Wikidata, and the like, so an engine can confirm you are who you say you are.
"sameAs": [
"https://www.linkedin.com/company/your-company",
"https://www.crunchbase.com/organization/your-company",
"https://www.wikidata.org/wiki/Q00000000"
]Beyond that, a lot of common advice (consistent name/address/phone everywhere, building a Wikipedia presence, earning mentions across the web) is reasonable and probably helpful, but it is industry inference, not something the engines have documented. Do it if it fits. Do not count on it as a guaranteed lever.
Structured data is not a shortcut
Google is clear on one limit: its 2026 guidance states that structured data “isn’t required for generative AI search, and there’s no special schema.org markup you need to add” to be eligible. You cannot buy your way in with markup tricks. Authority is earned the slow way, by being a genuinely credible source, clearly presented. That is the part no competitor can fake faster than you can.
