Frequently Asked Questions

For general web content, aim for grade 6-8 (Flesch-Kincaid Reading Ease of 60-70). This is the level of most successful blogs and news sites. Academic writing typically scores grade 12-16.

Readability formulas are approximations based on sentence length and syllable count. They work well for English prose but may give misleading results for code, poetry, or non-English text.

The top factors are: long sentences (over 25 words), multisyllabic words, passive voice, and dense paragraphs. The analyzer identifies all of these and suggests specific fixes.
