Reframe it: nobody needs a 'blog'. Businesses need PAGES that answer what buyers search. A plumber ranks from twelve excellent service-and-question pages ('water heater replacement cost in Franklin') faster than from a hundred news-style posts, because intent pages match money searches.
There's no magic post count: one page can rank for a specific local term; competitive terms need both a better page and site-wide credibility. Publishing cadence matters less than accumulating pages that each target a real search. Our answer-the-questions model over calendar-filling.
Where blog-style content earns its place: demonstrating expertise (E-E-A-T), feeding AI answers, and giving links something to point at. Write when you have an answer worth ranking; skip the 'holiday hours' posts.
