Readability Score Checker

What is Flesch Reading Ease?

A score from 0–100. Higher is easier to read. Aim for 60–70 for general web content. Scores above 80 suit a broad audience; below 50 is challenging for most readers.

What is Flesch-Kincaid Grade Level?

The US school grade level required to understand the text. A score of 8 means an 8th grader can read it. Most online content should target 7–9 for broad accessibility.

What is the Gunning Fog Index?

Measures readability based on sentence length and complex words (3+ syllables). A score of 12 corresponds to high school, 17 to college graduate. Target under 12 for general audiences.

How does readability affect SEO?

Google's Helpful Content system favors content written for humans, not search engines. Readable content reduces bounce rates and earns more time-on-page — both indirect ranking signals.

How can I improve my readability score?

Use shorter sentences (aim for 15–20 words on average), prefer simple words over complex ones, break up long paragraphs, and use bullet points or headers to guide readers.
