Why readability matters for SEO and AI
Clear writing keeps visitors reading, and it's easier for Google and AI assistants to extract and quote. Short sentences with one idea each are exactly the kind of passage that ends up in answers.

Flesch Reading Ease uses average sentence length and syllables per word. Syllables are estimated, so treat scores as a guide.
