Keyword Density Checker for App Descriptions
Google Play indexes your full description, so it matters how often your keywords appear and how early. Paste the description and your keywords to see each one's count and density, a warning when any passes 2.5% (a common stuffing threshold), and whether it appears in the opening 167 characters and the first paragraph.
Add a description and at least one keyword to see the numbers.
Three steps, no sign-up
Paste your full description
Up to Google Play's 4,000 characters. Paragraph breaks matter: the first paragraph is checked separately.
Add the keywords you target
One per line or comma separated. Phrases like "habit tracker" are matched as phrases, including the plural.
Read the result
Each keyword gets a count, a density and a status: missing, light, good or too high. The most repeated words are listed too, which catches accidental stuffing of words you did not think of.
How to read the numbers
- Density is keyword words divided by total words. A two-word phrase used 3 times in 300 words is 2%.
- Above 2.5% is flagged. Repetition past that point reads as stuffing to people and risks a policy problem on Google Play.
- Under 0.5% is light. One natural mention in a long description may be too few to signal relevance.
- Use your main keyword in the first paragraph, where readers and the store both look first.
- Apple does not index descriptions, so on iOS write for readers and put keywords in the title, subtitle and keyword field.
A worked example
A 138-word Google Play description for a habit app (load it with "Try the example" in the tool), checked for three keywords.
| In: Keywords | habit tracker, streak, meditation |
| Out: habit tracker | 4 uses, 5.8%, too high. Cut two mentions or vary the wording. |
| Out: streak | 2 uses, 1.4%, good, but not in the first paragraph |
| Out: meditation | 0 uses, missing. Add one natural mention if you want to rank for it. |
The numbers above come from the same logic the tool runs. Paste your own description to see yours.
