Google — Guidance on third-party SEO tools & advice

Google Search Central’s first-party guidance on relying on third-party SEO tools, services, and advice — the authoritative primary behind the spoke’s trade-press coverage (google-guidance-seo-authority).

Citable claims

• Google doesn’t evaluate or endorse third-party services — be skeptical of any tool/agency claiming to be “acceptable” or “approved” by Google Search.
• Third-party metrics aren’t Google’s: such services can’t access Google’s internal ranking data and can’t guarantee outcomes — “predictions are their own and… may not happen” — yet users often misread third-party scores as coming from Google itself.
• Extra scrutiny for AEO/GEO tools: be cautious of services promising gains for AI search formats (“AEO” / “GEO” tools) — the same caution as the AI optimization guide‘s anti-hacks stance.
• Use first-party data instead: Google recommends Search Console, which gives “key information and data directly from Google Search itself.”
• Vet external advice against official Google documentation — does a claim cite official guidance, or is it opinion presented as fact?
