What is Readability Score?

A numerical measure of how easy text is to read, typically calculated using formulas based on sentence length and word complexity.

Readability Score Explained

Readability scores quantify how difficult text is to read. The most common formulas — Flesch Reading Ease (0-100 scale), Flesch-Kincaid Grade Level (school grade equivalent), Gunning Fog Index, and Coleman-Liau Index — analyze sentence length, word length, and syllable count. For business content, a Flesch-Kincaid grade level of 8-10 is ideal — accessible to a broad professional audience without oversimplifying. Readability is one dimension of content quality, not the only dimension.

Frequently Asked Questions

What is a good readability score for business content?

Flesch Reading Ease: 60-70 (plain English). Flesch-Kincaid Grade Level: 8-10. Gunning Fog: 10-12. These ranges make content accessible to most professionals while maintaining substance.

Does readability score affect SEO?

Readability is not a direct Google ranking factor. However, readable content has lower bounce rates, higher time-on-page, and more engagement — all of which correlate with better rankings.
