Frequently asked questions

What is a Flesch Reading Ease score?
The Flesch Reading Ease score measures how easy a piece of text is to read. It ranges from 0 to 100 — higher is easier. A score of 60–70 is considered standard and easy to understand for most adults. The formula considers average sentence length and average number of syllables per word.
What is a good readability score for SEO?
For most web content, aim for a Flesch score between 60 and 70. Blog posts often target 65–75. Technical content may naturally score lower. Google doesn't directly rank by readability, but content that is easy to read tends to have lower bounce rates and more engagement — which indirectly helps rankings.
What is Flesch-Kincaid Grade Level?
The Flesch-Kincaid Grade Level translates the reading ease score into a U.S. school grade level. A grade level of 8 means an 8th grader can understand the content. Most general-audience content should target grades 6–9. Lower grade levels mean simpler, more accessible writing.
Does readability affect AI search citations?
Yes — AI models like ChatGPT and Perplexity tend to cite content that is clear, well-structured, and easy to understand. A high readability score signals that your content is well-written and authoritative, which increases the chance of being cited in AI-generated answers.
How can I improve my readability score?
The most impactful changes are: (1) Shorten your sentences — aim for 15–20 words each. (2) Use simpler words — replace 3-syllable words with shorter alternatives. (3) Use active voice instead of passive. (4) Break long paragraphs into 2–3 sentences. (5) Use bullet points and headers to structure information.
