Frequently asked questions
What does the readability score actually measure?
It's the Flesch-Kincaid reading-ease score, a formula based on average sentence length and syllables per word. Higher scores (up to 100) mean easier-to-read text; lower scores mean denser, harder-to-parse writing. It's a proxy for how much effort a reader (or an AI system summarizing your page) needs to extract the meaning — not a judgment on whether the content itself is good.
Is a higher readability score always better for SEO?
Not automatically. Google doesn't rank pages directly on Flesch-Kincaid score, but content that's needlessly dense tends to have worse engagement signals (time on page, bounce rate) and is harder for AI-search systems to lift a clean, quotable answer from. A technical or academic topic will naturally score lower than a general-audience blog post, and that's fine — the score is most useful as a relative check against similar pages, not an absolute target.
Why does the tool also show word count and reading time?
Word count and reading time give context to the readability score — a 200-word page and a 3,000-word page can carry the same score but read very differently in practice. Reading time is estimated from word count using a standard reading-speed assumption, not measured from real user behavior.
What happens if the page's main content can't be extracted?
If the tool can't find substantive content on the page (an empty or mostly-JavaScript-rendered page, for instance), the readability score comes back empty rather than a misleading number computed from navigation and footer text. Try a URL that renders its main content in the initial HTML response.
