Frequently asked

What does the SEO score check?

Meta tags (title, description, canonical), heading hierarchy (one H1, logical H2/H3), content depth (word count, readability, keyword density), internal linking (number, anchor diversity), structured data (schema.org JSON-LD), Core Web Vitals (LCP, CLS, FID), and AI visibility (AIO/GEO coverage).

How does it differ from PageSpeed Insights or Ahrefs?

PageSpeed measures performance. Ahrefs audits backlinks. This tool focuses on the on-page basics most teams skip: missing schema, broken heading hierarchy, thin content. It's the fastest way to find the 3 fixes that bump you a band.

How does it work under the hood?

We fetch your page server-side (10-second timeout, 5MB cap), parse the HTML, and score 16 signals across meta, structure, content, schema, AI signals, and technical. Nothing is stored; each scoring run is stateless. The PostWyse SEO Score agent runs a deeper version of this on every draft for paid customers.
