This handles H1 through H6 optimization when you're trying to fix heading hierarchy or structure content for SEO. It checks for project context first to grab target keywords, then walks you through single H1 per page, logical nesting without skipping levels, and keyword placement in subheadings. The output gives you an H1 recommendation plus a full H2 through H6 outline with hierarchy validation. Honestly most useful when you inherit a mess of multiple H1s or random heading levels, since it enforces the basic rules search engines expect. Connects well with title tag and content optimization skills if you're doing broader SEO work.
