What this checks

Readability is not a ranking factor, and anyone telling you otherwise is guessing. It matters because pages people can read are pages people finish, and finishing is what turns a visit into an enquiry.

  • Flesch Reading Ease score out of 100
  • Flesch-Kincaid grade level
  • Average sentence length
  • Average syllables per word

How to act on the result

  • Below 50 usually means sentences are too long rather than words too complex.
  • Split any sentence carrying more than one idea.
  • Technical audiences tolerate lower scores. Consumer pages should aim for 60 or above.

Frequently asked

Does readability affect SEO?

Not directly. Google has never confirmed a readability signal. It affects engagement, and engagement affects whether your page satisfies the search, which does matter.

What score should I aim for?

Around 60 for a general audience, which is roughly the level of a broadsheet newspaper. Professional and technical pages commonly sit in the 40s and that is fine for their readers.

How is the score calculated?

The Flesch Reading Ease formula, using average sentence length and average syllables per word. It is a rough instrument. Treat a difference of a few points as noise.

My score is low but my audience is technical. Is that a problem?

No. Write for your readers. Use the score to catch pages that are accidentally dense, not to flatten your writing.
