Keep visitors reading
Easy copy holds attention. The clearer your writing, the longer people stay and the more of your message lands.
Reach a wider audience
A lower grade level means more people understand you quickly, including skim readers and non-native speakers.
Convert more readers
When the offer is easy to understand, more people act on it. Clarity is one of the simplest ways to lift conversions.

FAQs
What is a readability score?
A readability score estimates how easy your text is to read, usually as a US school grade level or an ease score from 0 to 100. It is based on factors like sentence length and the number of syllables per word. Lower grade levels and higher ease scores mean your writing is simpler and easier for more people to understand.
What is the Flesch Reading Ease score?
The Flesch Reading Ease score rates text from 0 to 100, where higher is easier. Scores of 60 to 70 are considered plain English that most adults read comfortably, 70 to 90 is easy, and below 30 is very difficult and best suited to academic or technical readers. This tool calculates it live as you type.
What is the Flesch-Kincaid grade level?
The Flesch-Kincaid grade level converts your text into the US school grade needed to understand it. A grade level of 8 means an average eighth grader could read it. For marketing and web copy, aiming for grade 6 to 8 keeps your writing clear and accessible to the widest audience.
What is a good readability score for web copy?
For landing pages, ads and most web content, aim for a Flesch Reading Ease of around 60 or higher, or a grade level of about 6 to 8. Clear, simple writing converts better because more visitors understand it quickly. Technical or specialist audiences can handle harder text, but plain language wins for general marketing.
How can I improve my readability score?
Use shorter sentences, swap long words for simple ones, cut filler, and break text into short paragraphs. Reading your copy aloud helps you catch sentences that run too long. Small edits like splitting one long sentence into two often lift the score noticeably.
Does readability affect SEO?
Readability is not a direct Google ranking factor, but it strongly affects how people engage with your page. Clear, easy-to-read content keeps visitors on the page longer and helps them take action, which supports better performance. Hard-to-read pages tend to lose readers quickly.
Is this readability checker free?
Yes. The readability score checker is 100% free with no signup and no limits. Check as much text as you like, for blog posts, landing pages, emails or anything else, without paying anything.
Is my text stored anywhere?
No. The tool runs entirely in your browser using JavaScript. Your text is never uploaded and never leaves your device, so you can safely check unpublished drafts and copy.
