What is a readability score?

A readability score estimates how easy your writing is to understand, based on sentence length and word complexity. The best known is the Flesch Reading Ease score, from 0 to 100, where higher is easier. The Flesch-Kincaid grade level and Gunning Fog index translate that into a US school grade, so you can match your writing to your audience.

Why readability matters for SEO

Clear, scannable content keeps readers on the page and helps them get value fast, which supports engagement and conversions. Search engines aim to surface content people can actually use, so writing that's easy to read is rarely a disadvantage. For most web audiences, aim for plain, conversational English around a 7th to 9th grade level.

Frequently asked questions

What is a good Flesch Reading Ease score?

For general web content, aim for 60 or above, which reads at roughly an 8th to 9th grade level. Higher scores are easier to read.

What is the Flesch-Kincaid grade level?

It converts your text's difficulty into a US school grade. A grade level of 8 means the average 8th grader could understand it.

How is readability calculated?

Mainly from average sentence length and average syllables per word. Shorter sentences and simpler words produce easier scores.

Shorten long sentences, prefer common words, break up big paragraphs, and use headings and lists to make the page scannable.

Does readability affect SEO rankings?

Not as a direct factor, but readable content improves engagement and comprehension, which support your overall SEO performance.

For most audiences, a 7th to 9th grade level is a safe target. Technical or academic audiences may expect more complex writing.
