Why readability matters

People skim, and they bounce when copy feels like work. Clear, easy-to-read writing keeps visitors on the page, helps them understand your offer and makes them more likely to act.

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.

Edit with instant feedback

Watch the score change as you rewrite, so you can see exactly which edits make your copy clearer in real time.

Students and writers

FAQs

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.
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.
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.
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.
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.
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.
