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
What is a good Flesch Reading Ease score?
For general web content, aim for 60 or higher (plain English). Scores of 70–80 are very accessible; below 50 reads as fairly difficult and is better suited to technical or academic audiences.
How is the grade level calculated?
The Flesch-Kincaid formula combines average sentence length and average syllables per word. Longer sentences and more multi-syllable words raise the grade level.
Is my text stored?
No. All analysis runs in your browser — your text is never uploaded or saved.
Should I always aim for the lowest grade level?
Not necessarily. Match your audience: a developer tutorial can run higher than a consumer landing page. The goal is appropriate clarity, not the lowest possible number.
