After Google AdSense rejected the site for "low-value content," I reviewed and strengthened content across the whole site. I added explanatory content such as usage guides and FAQs to each tool page, and rewrote the About page and the blog category introductions in much more detail.
While reviewing all 80-plus published posts, I found an unexpected problem. Many posts created by the automated writing pipeline used the AI response's opening greeting as the title instead of the actual topic. The body content itself was solid, but the titles were hiding its value, so I extracted the real headings from each post's body and replaced the titles in bulk.
Building on everything I learned, I created and released the AdSense Precheck tool so other site owners can check their own sites before an AdSense review.
