About Readability
What readability scores measure
Readability formulas estimate how much effort a piece of text demands from a reader, using two things that are easy to count: how long the sentences are and how long the words are. Long sentences hold more clauses to keep in mind; long words are, on average, rarer and more abstract. Neither measure understands meaning, which is why a clear technical paragraph can score badly and a rambling one can score well.
The Flesch Reading Ease score runs from 0 to 100, higher being easier. Most web copy sits comfortably between 60 and 70. Below 50 the text starts to read like an academic paper; above 80 it reads like a children's book, which is rarely the aim.
How to read the numbers
- 90 to 100: very easy. Short sentences, everyday words.
- 60 to 70: plain English, the range most published web writing lands in.
- 30 to 50: difficult, typical of academic and legal text.
- Below 30: very difficult, usually a sign of long sentences packed with long words.
How to improve a low score
Split sentences that carry more than one idea. Prefer the short word where it means the same thing. Cut qualifiers that add length without adding precision. Then read the passage aloud: if you run out of breath, the reader runs out of patience.
Do not chase the score past the point where the writing serves the reader. Some subjects need long words, and some sentences need to be long to be accurate. The score is a warning light, not a target.
Does readability affect SEO?
Not directly. Google does not rank pages by Flesch score. It matters indirectly: text that is easy to read is read further, shared more and cited more, and those are the signals that do move rankings. It also matters for AI search, where a passage that states its point plainly is far easier to quote.
