Use tools to find review items, not guarantees
A checker can flag missing files, broken links, thin pages, mixed canonical signals, invalid JSON-LD, or missing publisher pages. It cannot guarantee that Google will index a page, rank it well, approve advertising, or interpret every signal exactly the way a human reviewer would.
Start with the practical checks
For a small static site, the most useful checks are usually simple: does the page load, does it have a clear title, does it have useful visible content, do important links work, is the sitemap clean, are robots.txt and ads.txt reachable, and are canonical URLs consistent?
Avoid fake optimization habits
Do not chase keyword-density targets, artificial SEO scores, or copied checklist language. A better page gives the reader a clear purpose, useful explanations, visible ownership, working navigation, and honest limits.
Document what you fix
When a tool flags a problem, fix the source file, retest the public URL, and keep notes for major changes. This is especially useful for static sites where old folders, deleted pages, and sitemap entries can linger after a rebuild.
