E-E-A-T for a Solo Developer Site: Proving You Actually Used the Tools

E-E-A-T (Experience, Expertise, Authoritativeness, Trust) sounds like SEO jargon until you realize what it means for a small site: you have to prove you are not a content farm. A solo developer can out-earn this simply by being honest in a way that scale cannot fake.

The signals a solo site can actually control

1. Real use. "No review without real use" is not a slogan — it is the core signal. Screenshots with timestamps, real costs, real problems hit, and the failures. A generic "best of" list written from spec sheets has none of this.
2. Named experience. "I ran SQLite in production for years" is a claim; "here is the exact malformed error, the backup I took, and the recovery output" is evidence. Specific beats confident.
3. Transparent math. When a review says "worth it," show the numbers — the calculator on the page. Letting readers verify your arithmetic builds trust no marketing copy can.
4. Disclosure. Explicit affiliate disclosure is not just a legal checkbox; it is a trust signal. "We may earn a commission, and we only recommend what we used" is the exact sentence a skeptical reader wants.
5. Consistency. A site that publishes small, specific, first-person posts over months accumulates more authority than one that dumps a hundred generic articles in a week.

What a solo site should not fake

• Traffic or authority you do not have. Nobody mistakes a fresh domain for ZDNet.
• Tests you did not run. The internet is full of "I tested X" posts that clearly never opened X. That is now detectable and it destroys trust permanently.

The math that wins

A solo site cannot out-Google the giants on volume. It can out-trust them on specificity — a real recovery walkthrough, a real cost ledger, a real "here is the calculator, check my work." In an era of AI-generated content, evidence of a human who actually did the thing is the rarest and most valuable signal.

Use the calculator below to be honest about a tool's value in your own reviews — showing the math is part of the trust.
