Keyword density checker
Paste your Google Play description or any app store metadata and see which keywords and phrases you're actually emphasizing, the density of each, and where a term is repeated so often it reads as keyword stuffing. Built for ASO — density is a Google Play signal, not an iOS one.
Start typing or paste your metadata to see your top keywords ranked by density.
Everything runs in your browser — nothing you paste is uploaded or stored. Density is the share of total words a term represents. Words above 5% are flagged as high-density; the sweet spot for a primary keyword in a Google Play description is usually a handful of mentions, written naturally.
How to read it
Where keyword density actually matters
The two stores read your description differently, so the same metadata calls for two different mindsets. Density is a Google Play and SEO concept — on iOS the game is coverage, not repetition.
Full description is indexed
Google reads the whole 4,000-character description word for word. Mentioning a primary keyword a few times signals relevance, but stuffing it reads as spam — Google's policy penalizes it, and shoppers bounce. Aim for natural copy where each key term lands three to five times and no single word dominates.
Description isn't indexed
Apple ignores the description for search and counts each keyword once in the name, subtitle and hidden keyword field. Repeating a word earns nothing and wastes characters. On iOS, optimize for coverage — fit as many distinct relevant terms as you can — not density. Use this tool to spot accidental duplicates across those fields.

FAQ
Keyword density, answered
What is keyword density in ASO?
Keyword density is how often a keyword appears as a percentage of the total words in a piece of text. In ASO it mostly matters for the Google Play full description, which Google indexes word for word: a term that appears a few times signals relevance, while one that appears too often reads as keyword stuffing and can hurt conversion. On the Apple App Store the description isn't indexed, so density there has no ranking effect.
What's a good keyword density for a Google Play description?
There's no official number, but a useful guideline is to mention each primary keyword roughly three to five times across the 4,000-character description and keep any single word under about 5% of total words. Write natural, readable copy a human would write rather than chasing a percentage — Google's policy penalizes keyword stuffing, so let density follow clarity.
Does keyword density matter on the Apple App Store?
No. Apple doesn't index the long description for search, and in the indexed fields — name, subtitle and the 100-character keyword field — each keyword is counted once, so repeating a word gives no extra ranking benefit and only wastes characters. On iOS the priority is keyword coverage (how many distinct relevant terms you include), not density. More in our guide to App Store ranking factors.
How do I avoid keyword stuffing in my app description?
Write for the user first, then check density. Use each primary keyword a few times in natural sentences, reach for synonyms and related phrases instead of repeating the exact term, and watch for any single word climbing above roughly 5% of total words. This checker flags high-density words so you can rephrase before you publish.
Is my metadata sent anywhere when I use this tool?
No. The keyword density checker runs entirely in your browser — nothing you type is uploaded, stored or sent to a server, so you can safely analyze unreleased metadata.
