Content NLP & readability analyzer
Readability scores and keyword densities represent statistical approximations calibrated for English prose. Search engines evaluate topical authority, helpfulness, and search intent rather than rigid keyword frequency targets.
Standard: Computes 1/2/3-gram distributions alongside Flesch, Flesch-Kincaid, Gunning Fog, and Coleman-Liau indices.
Frequently asked
Direct answers for search, answer engines, and generative crawlers.
Keyword density is the percentage of times a word or phrase appears relative to total content words. In modern search optimization, an optimal keyword density for primary search phrases is typically between 1% and 2.5%. Higher frequencies can trigger search engine penalties for "keyword stuffing."
