What the readability score means
The Flesch Reading Ease score estimates how hard your text is to read from sentence length and word complexity. Scores of 60-80 read as plain English - the sweet spot for web content, where visitors skim and decide in seconds. Below 40, most readers struggle and bounce. This is not about dumbing content down: clear writing on a complex topic consistently outperforms complicated writing on the same topic, for both human readers and the AI systems summarizing your pages.
Using keyword density without keyword stuffing
Keyword density stopped being a ranking lever years ago, but it remains a useful diagnostic in two directions. If your main topic barely appears (under ~0.5%), the page may never establish what it is about. If a phrase appears far above ~2-3%, the copy likely reads as stuffed - to visitors and to Google's spam systems. Aim for natural coverage: your core term, close variants, and the related vocabulary a knowledgeable writer would use anyway.
Frequently Asked Questions
Aim for 60-80 ("plain English"). Marketing pages and blogs serving general audiences should sit comfortably in that band; technical B2B content can run lower, but anything under 40 will lose a large share of readers.
There is no magic percentage Google rewards - density is a sanity check, not a target. Roughly 0.5-2% for your primary topic keeps the page clearly on-topic without reading as stuffed. Write for the reader first, then verify nothing is wildly over- or under-represented.
As long as the topic genuinely needs - thin 300-word posts rarely compete, but padding to hit 2,000 words hurts engagement. Look at what currently ranks for your target query and match its depth while being more useful or current.
