Keyword Density Checker

For Google Play, most ASO practitioners target a density of about 2–3% for the primary keyword — roughly 8–12 natural mentions in a 4,000-character description — with secondary keywords appearing 3–5 times each. Densities much above 4–5% start to read as keyword stuffing, which Google explicitly penalizes and which hurts conversion because the text stops sounding human.

For the Apple App Store the calculus is different: Apple does not index the description for search rankings. Density still matters there for conversion and for the small subset of surfaces where description text is used, but your ranking keywords belong in the name, subtitle, and keyword field instead.

The analyzer splits your text into words, normalizes case and punctuation, and removes stop words — common words like “the”, “and”, or “your” that carry no search value — using language-specific lists covering English, Spanish, French, German, Turkish, Japanese, Korean, Chinese, Arabic, and more. Generic ASO filler words like “app”, “free”, and “best” are filtered too, so the table surfaces the terms that actually differentiate your listing.

Density is calculated as the keyword’s share of all meaningful words (not raw words), which is the measure that best reflects how prominent a term feels to both algorithms and readers.
