Frequently Asked Questions
What readability score should I target for SEO?▾
For most web content, aim for a Flesch Reading Ease score of 60-70 or a Flesch-Kincaid Grade Level of 7-8. This makes your content accessible to the widest audience, which can improve engagement, time on page, and lower bounce rates — all signals Google uses.
Does readability directly affect SEO rankings?▾
Readability is not a direct Google ranking factor. However, content that is easier to read tends to have better user engagement metrics (lower bounce rate, longer dwell time), which can indirectly improve rankings. Google's guidelines emphasize creating content for users first.
