SEOrd

A TypeScript content SEO analyzer library, pronounced sword, that runs a rapid analysis on rich text content. It checks SEO friendliness through factors such as keyword density, meta description, headings structure with a single h1 and keywords in headings, and internal and outbound link analysis including duplicates. Results include warnings, minor warnings and good points, plus a score. It is synchronous, fully typed and light on dependencies, relying only on cheerio, and its analyzeSeo function takes content and options. The author built it after struggling to find a good SEO analyzer for this job. It applies standard on-page rules and is meant as a reference or supplement to help improve a score. A migration guide covers moving from older 0.0 releases.
