What is Readability in SEO?

**Readability** measures how easy it is for a reader to comprehend a written text. In search engine optimization, readability is a major user experience factor. If a page has complex vocabulary and long, run-on sentences, visitors will quickly bounce, sending negative ranking signals to search engines.

Using formulas like **Flesch Reading Ease** and **Flesch-Kincaid Grade Level** allows copywriters to align their content structure with their target audience's grade levels, securing higher user engagement and average session durations.
