## How to use a readability score on a launch page

Landing pages convert better in plain English (Flesch 60+). Keep sentences near 20 words and cut stacked jargon.

Syllable counts here are a vowel-group estimate, not a dictionary. Use the score to rewrite, not to brag.

Pair with word count and reading time when you are sizing a blog or Premium+ article.
