Flesch Score Guide
What Is the Readability Score Checker?
The Readability Score Checker measures how easy your text is to read using the Flesch Reading Ease formula, which scores writing from 0 to 100 based on sentence length and syllables per word. Higher scores mean easier reading; the table above maps each range to a real-world reference point.
Readability matters for SEO indirectly but powerfully. Visitors who understand your page stay longer, scroll further, and convert more often; visitors who hit a wall of jargon bounce back to the search results. For most web content, including commercial pages, simpler writing wins even for expert audiences.
How to Use It
- 1Paste your draft into the text field.
- 2Read the Flesch score and see which difficulty band it lands in.
- 3Look at the supporting stats: average sentence length and syllables per word show which of the two is dragging the score down.
- 4Shorten the longest sentences, swap complex words for plain ones, and re-check until you land in your target band.
Frequently Asked Questions
What is a good Flesch Reading Ease score for web content?
Aim for 60 to 70 for general web content: that is plain English a typical 13 to 15 year old can follow. Marketing and e-commerce pages often benefit from 70+. Specialized B2B or technical content can sit lower, but even expert readers prefer clear writing: complexity should come from the ideas, not the sentences.
Does readability directly affect Google rankings?
Google says readability formulas are not a ranking factor. The effect is indirect: readable pages hold visitors longer, earn more links and shares, and answer queries faster, all of which correlate with better performance. Write clearly for readers, and the search benefits follow as a side effect.
How do I improve a low readability score?
Three moves handle most cases: split any sentence longer than about 25 words into two, replace multi-syllable words with shorter equivalents (utilize becomes use, approximately becomes about), and break long paragraphs so each carries one idea. Reading the text aloud instantly exposes the sentences that need surgery.
