What reading level should web copy aim for?

There is no single target, but plain-language guidance for a general audience usually aims around grade 8. Short sentences and common words help every reader, including experts skimming on a phone.

Does readability affect SEO?

Google does not use a readability score to rank pages. Clear writing still matters, because people stay on pages they understand and AI answers quote passages that state things plainly.

Does it work for languages other than English?

The reading-level scores use English formulas, so the analyzer withholds them for pages in other languages.

How much does the Readability Analyzer cost?
