Frequently Asked Questions

The formula is: 206.835 − 1.015 × (words/sentences) − 84.6 × (syllables/words). Scores range from 0–100 where higher means easier to read. A score of 60–70 is considered ideal for general audiences.

Keyword density is the percentage of times your target keyword appears relative to the total word count. An optimal range is 1–3%. Below 0.5% means the keyword may not register for SEO, while above 5% risks keyword stuffing penalties.

The tool uses a heuristic approach: it counts vowel groups (consecutive vowels = 1 syllable), adjusts for silent 'e' endings, and handles special cases like '-le' endings. It's not perfect but provides a reliable estimate.

N-grams are contiguous sequences of words. The tool shows the most frequently used 2-word and 3-word phrases in your content, helping you identify recurring themes and potential long-tail keywords.
