The main risk in AI content at scale is not one bad paragraph. It is repeating the same error across hundreds of pages. Put quality gates before generation, before publication, and after release. Check keyword ownership and search intent first. Then validate that the SEO title, meta description, and H1 each do their own job without drifting into different topics. Test links, evidence, duplication, and page type. Publish a small batch, monitor it, and keep a rollback path. Scale the checks before scaling the output.
