Free readability checker
Enter any URL to score its readability: the Flesch reading ease score, grade level, average sentence length, and word count. Instant, free, no signup.
Readable content gets read, shared, and cited. The Flesch reading ease score measures how easy your writing is to follow on a 0 to 100 scale, where higher is easier. This checker fetches any public page, extracts its body text, and scores it, along with the sentence and word stats that drive the number, so you can see whether your copy is scannable or a slog.
How to use the readability checker
Paste the URL and press Check. The tool pulls the page's main text, calculates the Flesch reading ease score and reading level, and shows the underlying stats: average words per sentence and total word count.
Use the checks to spot what is hurting readability, usually long sentences or thin content, and edit accordingly.
What is a good readability score?
For most web content, aim for a Flesch score of 60 or higher, which maps to roughly an 8th to 9th grade reading level and reads as plain, clear English. Technical or academic audiences tolerate lower; consumer content should be higher.
The two biggest levers are sentence length and word choice. Keep average sentence length under 20 words and prefer common words over jargon, and the score climbs fast.
Why readability matters for SEO and AI
Clear writing keeps readers on the page and makes your points easy to lift. AI engines quote sentences they can extract cleanly, so plain, well-structured copy is easier to cite. Dense, run-on writing is easy to skim past, for humans and models alike.
Readability is not a direct ranking factor, but it influences engagement and citability, both of which matter.
