The Flesch Reading Ease score rates text on a 0–100 scale — higher means easier to read. A score of 60–70 is ideal for most web content. Below 30 is academic-level difficulty. Above 80 is conversational and accessible. Most successful marketing content sits between 60–75.
Google measures engagement signals — time on page, bounce rate, scroll depth — all of which are directly tied to how easy your content is to read. Content written at a 7th–9th grade level consistently outperforms complex copy. Short sentences, active voice, and common vocabulary keep readers engaged and send strong positive signals to Google's algorithm.
