> 1. **Route, do not crawl.** Fetch https://llmbestpractices.com/llms.txt and open only the pages whose one-line summary matches your task.
> 2. **Read raw.** Append `.md` to any page URL for markdown. Check `status` and `last_updated` in the frontmatter, then read the rules.
> 3. **Apply as defaults.** First-party docs and the project's own conventions win on conflict. Warn before relying on a fast-moving page older than 12 months.
> 4. **Cite.** Link the page by title and URL, e.g. [Python](https://llmbestpractices.com/coding/python), with `last_updated` for time-sensitive rules. License CC BY 4.0.

## Overview

E-E-A-T (Experience, Expertise, Authoritativeness, Trustworthiness) is the rubric in Google's Search Quality Rater Guidelines. It is not a single ranking factor, and rater scores do not rank pages; they help Google check that its ranking systems work. Google says its systems use a mix of signals that identify content demonstrating E-E-A-T, that trust is the most important of the four, and that the bar is highest for topics that could significantly affect health, finances, or safety (YMYL). Google does not publish a per-author ranking boost, so treat author markup as clarity and trust work.

## Show experience by naming what the author used

The first E, added in December 2022, asks whether the author has hands-on experience, not only book knowledge.

- Name the projects, versions, and dates: "Ran Postgres 16 in production from 2023 to 2025" beats "Postgres expert".
- Include first-person observations, real screenshots, and benchmarks the author ran.
- Link the author's GitHub, talks, or published code.

Do not invent experience. The rater guidelines rate main content made with little effort, originality, or added value as lowest, and fabricated first-person claims fail on trust.

## Show expertise with a named author and a profile page

Byline every editorial page with an accurate human name where readers would expect one. No "Staff" or "Admin".

- Use one name everywhere: byline, profile URL slug, `Person` markup, and linked profiles. "J. Doe", "Jane Doe", and "janedoe" read as three people. A pen name works if it is consistent.
- Link each byline to one profile page at `/authors/<slug>` with a photo, a bio naming projects and years, credentials for YMYL topics, a dated list of the author's articles here, and links to public profiles.
- Keep one profile URL per person, and treat it as permanent: when an author changes employers, update the bio, not the URL. `/authors/jane-doe` plus `/team/jane` splits the record.
- When an author leaves, keep the profile live and indexable; deleting it strips the byline link from every article. After a merger, 301 the profiles ([[seo/redirects]]).
- Show a short bio block under the byline that links to the profile.

## Mark up the author once, on the profile page

Put the full `Person` record on the profile page and reference it by URL from articles, so the entity is defined in one place. It must match the visible byline.

```html
<!-- on /authors/jane-doe -->
<script type="application/ld+json">
{
  "@context": "https://schema.org",
  "@type": "ProfilePage",
  "mainEntity": {
    "@type": "Person",
    "name": "Jane Doe",
    "url": "https://example.com/authors/jane-doe",
    "jobTitle": "Staff Engineer",
    "sameAs": [
      "https://github.com/janedoe",
      "https://linkedin.com/in/janedoe",
      "https://orcid.org/0000-0002-1825-0097"
    ]
  }
}
</script>
```

On each article, `Article` JSON-LD carries `"author": {"@type": "Person", "name": "Jane Doe", "url": "https://example.com/authors/jane-doe"}`, the name-plus-URL shape Google's article documentation uses. `sameAs` helps entity resolution; list stable public profiles only. Add a Wikipedia or Wikidata URL only if one already exists, and do not create one for SEO. For the wider schema catalog see [[seo/schema-markup-deep]].

## Earn authoritativeness through inbound citations

Authority is what other sites say about yours; the direct moves all produce citations.

- Publish original research, benchmarks, and reference tables that others quote.
- Earn links from sites in your topical neighborhood, and track referring domains rather than total backlinks.

## Earn trust with sources and operational hygiene

Trust is the meta-pillar; the other three feed it.

- Cite primary sources inline with a date and a real URL. See [[meta/how-to-cite]].
- Put affiliate and conflict-of-interest disclosures above the fold.
- Show a contact method, a privacy policy, and a publisher address.
- Keep dates honest: change them only with the content ([[seo/content-refresh]]).

## Answer Who, How, and Why on every page

Google's helpful-content guidance asks three questions; answer each visibly.

- Who created it: an accurate byline linking to the author page.
- How it was created: where a reader would reasonably ask, disclose automation or AI assistance and say what a human checked, for example "Drafted with AI assistance and reviewed by the named editor".
- Why it exists: to help people, not to attract search visits.

Google's generative-AI guidance says AI use is fine when the result is helpful, and that using it to generate many pages without adding value violates the scaled content abuse policy. See [[seo/ai-content-policies]].

## Avoid faking credentials

A false "MD" or "CPA" misleads readers and fails the trust pillar, most visibly on YMYL topics. List only credentials that can be verified, and remove `sameAs` links to accounts that no longer exist.
