Plain English — most adults can read this comfortably.
Why readability matters for SEO
Content that's easy to read keeps people on the page, earns more shares, and converts better — all signals that correlate with stronger organic performance. Most general audiences read most comfortably at around a 7th–8th grade level; dense, jargon-heavy writing quietly costs you readers.
What the scores mean
Flesch Reading Ease runs 0–100, where higher is easier (60–70 is plain English). Flesch-Kincaid Grade Level estimates the US school grade needed to understand the text. Together they tell you whether your writing matches your audience's reading level.
How to improve a low score
Shorten sentences, prefer common words over jargon, cut filler, break long paragraphs apart, and use the active voice. Re-run the check after editing to confirm the score moved in the right direction.
Frequently asked questions
A good Flesch Reading Ease score for general web content is 60 or higher, which reads as plain English. Scores of 70 to 80 are very accessible, while anything below 50 reads as fairly difficult and suits technical or academic audiences.
The Flesch-Kincaid formula combines average sentence length with average syllables per word. Longer sentences and more multi-syllable words raise the grade level.
No, your text is not stored. All analysis runs in your browser, so nothing is uploaded or saved.
Aiming for the lowest grade level is not always right. Match your audience instead, since a developer tutorial can run higher than a consumer landing page. The goal is appropriate clarity, not the smallest possible number.
Paste the text into the checker above and read the Flesch-Kincaid grade level in the results. A score of 8 means a typical 8th grader can follow it, which suits most general audiences. Word processors bury a similar check in settings; here it runs on paste with no setup.
