Content Optimization

This handles the tactical side of on-page SEO: word count strategy, H2 keyword placement, avoiding keyword stuffing, and structuring content with tables and lists for featured snippets. It won't write your content, but it will audit what you have and tell you if your 800-word guide should actually be 1,500 words, if your H2s are cramming keywords unnaturally, or if you're missing table markup that could land a snippet. The keyword density guidance is refreshingly honest about it not being a ranking factor while still giving you 0.5% to 1.5% as a stuffing guardrail. Works best when you point it at existing drafts or outlines and let it catch structural gaps before you publish.
