E-E-A-T Credibility Signals

Apply ../00-blog-writing-guardrails/SKILL.md first; its Originality, Accuracy, and E-E-A-T gates are hard requirements. This skill turns that gate into concrete drafting and editing steps.

1. Author bio and credentials

• Write a visible author bio next to or beneath every post that states the author's relevant credentials, role, or track record on the post's topic; do not rely on a generic "Team" byline for topics where the reader needs to know who is speaking. [GOOGLE-EEAT-01]
• Make the author's credentials easy to find, either in the inline bio or a linked profile page, and keep them accurate to the author's actual professional reputation. [TRUSTPROJECT-INDICATORS-01]
• Mark up the byline with author structured data pointing to a Person (or Organization for house content) so the credential signal is machine-readable, not just visible text. [SCHEMAORG-AUTHOR-01]
• Maintain an "About us" or author-profile page that a reader or a Google quality rater can use to independently confirm the stated experience and expertise; do not let the on-page bio claim credentials the profile page contradicts or omits. [GOOGLE-QRG-01]

2. Disclosing methodology and first-hand experience

• When the post reports on a test, review, or experiment, state how it was done — what was tested, over what period, under what conditions — so a reader can judge whether the experience behind the claim is real and relevant. [GOOGLE-QRG-01]
• Prefer language that shows direct, first-hand experience with the product, process, or data ("we ran," "we measured," "we used this for X months") over language that only synthesizes other people's claims. [GOOGLE-EEAT-01]
• Disclose any conflict of interest (ownership, sponsorship, affiliate relationship with the subject) next to the claim it affects; a reviewer's own product review is not a trustworthy, independent source without that disclosure. [GOOGLE-QRG-01]

3. Linking to primary sources

• Link every statistic, quote, or factual claim to the primary source that backs it — the original study, standards body, or first-party dataset — not to a secondary blog post that merely cites it. [GOOGLE-EEAT-01]
• Place the citation inline or in a references section close enough to the claim that a reader or an AI system can verify it without leaving the page. [GOOGLE-EEAT-01]
