Why SEO matters for AdSense
AdSense approval and search rankings go together. A site that is well-structured for Google — clear titles, one H1 per page, descriptive alt text, fast loading, a clean sitemap — both ranks better and looks more credible to the AdSense review team. Poor on-page hygiene is a common reason new sites are rejected.
Work top-down
The items are roughly ordered by importance. Titles, meta descriptions and H1s affect every page and are the fastest wins. Then move to images, links and the technical items (sitemap, robots.txt, speed, mobile).
