Readability Score Checker: FAQ
What is the Flesch Reading Ease score?
Flesch Reading Ease rates text from 0 to 100 based on average sentence length and syllables per word. Higher is easier: 60 to 70 is plain English suitable for most web audiences, while scores below 30 read like dense academic or legal writing.
What is a good readability score for web content?
For most business and marketing pages, aim for a Flesch Reading Ease of 60 or above and a Flesch-Kincaid grade around 7 to 9. That keeps content accessible to a wide audience without dumbing down expertise.
What is the Flesch-Kincaid grade level?
Flesch-Kincaid grade translates readability into a US school grade. A grade of 8 means an average eighth grader can follow the text. Lower grades are easier; most successful web copy lands between grades 6 and 9.
What are Gunning Fog, SMOG, and Coleman-Liau?
They are alternative readability formulas. Gunning Fog and SMOG estimate the years of education needed to understand text, weighting complex or polysyllabic words. Coleman-Liau and ARI use character counts instead of syllables. Comparing several gives a more reliable picture.
How is the score calculated?
The tool counts sentences, words, syllables, and characters, then applies each standard formula. Syllables are estimated with a vowel-group heuristic, which is how most readability checkers approximate spoken syllables for English text.
Does readability affect SEO and AI visibility?
Readability is not a direct ranking factor, but clear, scannable content improves engagement, dwell time, and comprehension. AI answer engines also favor content that is easy to parse and summarize, so plain writing supports both SEO and GEO.

No. This is a client-side readability checker. All analysis runs locally in your browser and your text is never sent to Web Aloha servers.
