Frequently Asked Questions
What is Flesch Reading Ease?
A 0–100 score of text difficulty based on sentence length and syllables per word. Higher is easier: 60–70 suits most web content; 90+ is very easy.
What grade level should I target?
Grade 8–9 (Flesch-Kincaid) works for general web audiences — readable by most adults without feeling dumbed down. Technical audiences tolerate higher.
Does readability affect SEO?
Indirectly but meaningfully: readable pages get longer dwell time and lower bounce rates, which correlate with rankings. Google also explicitly values accessible content.
How accurate is the syllable counting?
The tool uses standard heuristic rules (vowel groups, silent-e handling) that are accurate for the vast majority of English words — precise enough for reliable scores.
