Readability Analyzer

Analyzes your content using four established readability formulas — Flesch Reading Ease, Flesch-Kincaid Grade Level, Gunning Fog, and SMOG Index — plus passive voice detection, long sentence flagging, and complex word analysis.

What Flesch Reading Ease score should I aim for?

For most web content, aim for 60–70 (8th–9th grade level). Blog posts, news, and product descriptions read best at 65+. Technical documentation can go lower. Plain language guidelines often target 70+ for consumer-facing content.

Does readability affect SEO?

Indirectly, yes. Google doesn't score readability directly, but clearer content leads to lower bounce rates, higher dwell time, and more shares — all behavioral signals that correlate with better rankings. Readable content is simply better content.
