Frequently Asked Questions
How is readability score calculated?

What is a good readability score for web content?
Flesch Reading Ease: 60-70 (8th-9th grade) for general web content. 70-80 for broad audiences. 50-60 for professional content. Most successful web content is written at a 6th-8th grade level. The tool shows your score against recommended targets.
What is the Flesch-Kincaid grade level?
It estimates the US school grade level needed to understand the text. Grade 6 = 11-12 year olds. Grade 8 = 13-14 year olds. Grade 12 = 17-18 year olds. Most newspapers target grade 6-8. Academic papers are typically grade 12-16. The tool calculates this automatically.
How do I improve my readability score?
Use shorter sentences (under 20 words). Choose simpler words (use vs utilize). Break long paragraphs. Use active voice. Avoid jargon. Add subheadings. Use bullet points. The tool highlights specific sentences and words that lower your score.
Does readability affect SEO?
Indirectly yes. Readable content has lower bounce rates, higher time on page, and more shares. Google's helpful content update favors user-friendly writing. While readability isn't a direct ranking factor, it improves user signals that affect rankings.
