Keyword Density Checker

We calculate N-Gram density using a precise formula: ((Phrase Count * Number of Words in Phrase) / Total Processed Words) * 100. This accurately reflects the percentage of your text occupied by that exact multi-word phrase.

Reading time correlates strongly with dwell time, a significant ranking factor. Search engines reward content that keeps users on the page longer. We estimate reading time based on an average adult reading speed of 200 words per minute.

Our tool flags any individual phrase with a density over 4% as potential keyword stuffing. While limits vary by niche, exceeding 3-4% often harms readability and risks algorithmic penalties from Google's spam updates.
