Is this tool free?
Yes. Toolinium Readability Checker is 100% free with no registration required.
What is a good Flesch Reading Ease score?
Scores of 60–70 are considered standard — easy to read for most adults. Scores above 70 are very easy (ideal for general audiences), while below 50 is considered difficult and more suitable for academic or technical content.
Does readability affect SEO rankings?
Google doesn't use readability scores as a direct ranking factor, but easier-to-read content keeps users engaged longer, reduces bounce rate and increases social shares — all of which positively influence rankings.
Is my content sent to a server?
