What does this painting ranking rest on?
We ranked each idea by how direct its evidence is. Ideas backed by our own painting search data come first, then ideas grounded in an EPA or Google source, then ideas that rest on how a painting business works. We didn't use figures from other trades to rank painting ideas.
The search data is Mindflow's: Google Ads search-volume estimates for "house painters," "painting contractor" and "interior painting," monthly from October 2022 to September 2026. Search volume isn't booked work, and estimates are rounded. Painting wasn't among the 8 trades in our Home-Service Visibility Study, so this page has no painting map or AI-answer figures.
Of the seven painting marketing lists we read on October 31, 2026, six numbered between 4 and 11 ideas and one gave no count. None ranked them or said what supports each one, and none used the EPA's lead-paint figures or Google's photo rules.
