Use primary sources for policies, laws, technical specifications, prices, and account workflows. Link directly to the relevant official section, not just a general homepage. Paraphrase accurately and explain your interpretation separately. If a fact changes, note when it was checked and revisit the article when the source updates.
Example: An article explaining ads.txt should link to Google’s ads.txt guide and explain that the reader must use the publisher ID shown in their own account. A sample record should use a clearly fictional placeholder. This gives the reader a verification route and avoids presenting an example as account-specific instruction.
Google’s AdSense readiness guidance encourages useful, unique content. Citations alone do not make an article useful; the explanation should help the reader understand and apply the source. Avoid copying long passages or paraphrasing a third-party article without adding analysis.
Use SiteReadyScore when a reader needs to check public-site signals after following your steps. Link the tool as a next action, but continue linking to Google for policy authority. SiteReadyScore is an independent aid and should never be presented as a Google product.
Reference practice: Official URL; exact section; date checked; concise explanation; clearly marked inference; working source link.
