FAQs
What formula is used?
Flesch-style approximations suitable for editing workflows. Use them to catch overly dense copy, not as a single quality score.
Does readability affect SEO?
Indirectly—clear pages help engagement signals and accessibility. There is no official “Flesch score” ranking lever.
Why do results differ from browser extensions?
Server-side fetches can see a different HTML payload than a logged-in browser session. Cross-check when debugging personalization or geo variants.
Can I suggest an improvement?
Email a short description of the workflow and a redacted example. Useful, repeatable suggestions get prioritized.
