Seo Optimizer

This handles the full SEO checklist: keyword density calculations, readability scoring (Flesch, grade level, sentence length), meta tag validation, heading hierarchy checks, and content gap analysis. You'd use it when optimizing blog posts before publishing or auditing existing content that's underperforming in search. It generates prioritized fix lists sorted by impact, from critical issues like missing meta descriptions to medium priority items like schema markup opportunities. The output is pleasantly specific with before/after examples and actual implementation checklists rather than vague advice. One honest take: the E-A-T evaluation and competitor analysis components make this more strategic than the usual keyword density checkers.
