Readability Score

The Readability Score tool calculates the Flesch Reading Ease score and grade level estimate for any text you paste, then provides actionable suggestions to make your content more accessible to a wider audience. Readability has a direct impact on SEO performance because Google rewards content that satisfies user intent quickly — if visitors land on your page and struggle to understand your writing, they bounce back to the search results, which sends a negative engagement signal that erodes your rankings over time. Studies consistently show that the highest-performing web content reads at a 7th to 8th grade level, even when the topic is technical or specialized. A Flesch score between 60 and 70 hits the sweet spot for most audiences. If your score falls below 50, your content is likely losing casual readers; above 80 and you may be oversimplifying in a way that fails to demonstrate expertise, which matters for E-E-A-T signals in competitive niches. When reviewing your results, focus on the sentence length analysis first: sentences longer than 20 words are the most common readability killer, and splitting them is usually the fastest fix. Next, examine the word complexity score and replace multi-syllable jargon with simpler alternatives wherever the meaning is preserved — for example, use 'start' instead of 'initiate' or 'help' instead of 'facilitate.' Paragraph length matters too: keep paragraphs under four sentences for web content. Pro tip: run your content through this tool after every editing pass, not just once, because edits that improve accuracy often accidentally increase complexity, and catching that regression early saves time.
