ASO Keyword Density Analyzer
Paste your app description to analyze keyword density. Ensure you are targeting the right terms without keyword stuffing. Crucial for Google Play ASO.
App Description
Google Play ASO Strategy
Google indexes your full description for search. Aim for a density of 2–3% for your main keywords. Over 5% may trigger spam penalties. Spread keywords naturally.

WhixFrame generates App Store and Google Play descriptions optimized for keyword density and conversion.
What This Tool Does
This analyzer scans an App Store or Google Play description and shows exactly how often each keyword appears and what percentage of the total word count it makes up. It is built for indie developers and solo marketers writing their own store listings who want a straightforward answer to two questions: am I using my target keywords often enough to rank, and am I repeating any of them so much that it reads as spam.
Paste your draft description, pick your platform, and the tool strips out common stop words, counts every remaining term, and flags anything that looks under-optimized or over-stuffed. No account, no character limit tracking across sessions, nothing saved on a server. It is meant to be used the way you'd use a spell checker: paste, review, fix, done.
Why Keyword Density Matters (Without Becoming Spammy)
Keyword density is simply how often a term appears relative to the total word count of your text. On Google Play, this number matters a lot because Google's Play Store algorithm indexes your full description, up to 4,000 characters, to understand what your app does and who should see it in search results. If your primary keyword never appears, or appears once in 400 words, the algorithm has little signal to rank you for it.
The failure mode on the other end is keyword stuffing: repeating a phrase far beyond what a human would naturally write, purely to game the ranking. Google's natural language processing is good at detecting this, and the practice can suppress your ranking for that keyword or, in severe cases, trigger a policy review. The goal is a density that reads naturally to a person while still giving the algorithm a clear signal, which in practice tends to land in a moderate range rather than at either extreme.
How It Works
Write a draft description first
Focus on benefits, features, and a natural reading flow before you think about keyword count at all.
Paste it into the analyzer
Select iOS or Android above, then paste your full description into the text box.
Check your top keywords
Review the table of your top 20 terms, their raw count, and their density percentage.
Adjust anything flagged
On Android, terms marked "Increase" are underused and terms marked "Stuffing" are overused. Revise and re-paste until your primary keywords land in a healthy range.
Platform Differences
Apple App Store
Apple does not index your visible description for search ranking at all. Instead, it uses a separate, hidden 100-character keyword field (comma-separated, not shown to users) along with your 30-character app name and 30-character subtitle. Because of this, density in your iOS description has no ranking effect: write it purely to convert readers into installs, and put your actual keyword targeting into the keyword field where every character counts. Our character counter tool tracks that 100-character field precisely.
Google Play
Google Play has no hidden keyword field. The algorithm ranks your app based on the visible text in your title, short description, and full description, which is why density in the full description is a genuine ranking factor here. A commonly cited working range for primary keywords is roughly 2 to 3 percent, spread naturally rather than clustered in one paragraph, with density above 5 percent generally considered stuffing territory.
Frequently Asked Questions
What is a good keyword density for app descriptions?+
There is no single official target. A commonly used range for your primary keyword on Google Play is 2 to 3 percent, repeated naturally across the full description rather than crammed into one section. Secondary keywords can appear less often, and long-tail phrases just need to show up once or twice in an exact match.
Can keyword stuffing get my app rejected?+
Yes. Severe, unnatural repetition can violate Google Play Developer Policies and lead to a suspension or forced edit, and even short of a formal rejection, Google's algorithm can actively lower your ranking for a keyword it detects as stuffed. On iOS, stuffing your visible description does nothing for ranking since Apple doesn't index it, so it only hurts your conversion rate.
Does this work for both the App Store and Google Play?+
Yes, but the two platforms use the numbers differently. Google Play ranks on the visible text you paste here, so density matters directly. Apple ranks on a separate hidden keyword field and your app name and subtitle, not on the description body, so use this tool on iOS mainly to keep your description readable rather than to chase a ranking number.
Why does the tool ignore words like "the" and "and"?+
Those are stop words: extremely common words that carry no keyword meaning and would otherwise dominate the count. Removing them surfaces the terms that actually matter for ASO.
Common Mistakes
Repeating the same phrase back to back
Placing "photo editor" three times in one sentence reads as spam to both users and Google's algorithm. Spread mentions across different paragraphs instead.
Ignoring long-tail keyword variants
Only targeting your single head keyword misses search traffic. Weave in related phrases like "vintage film camera effects" alongside your main term to capture long-tail searches.
Stuffing the subtitle or keyword field
On iOS, cramming unrelated terms into the 30-character subtitle or 100-character keyword field wastes space that should hold distinct, high-value terms, not repeats of your app name.
Optimizing the iOS description for density
Since Apple doesn't index the description, chasing a density percentage there trades away conversion-focused writing for no ranking benefit.
