How to use keyword density for ASO
What is keyword density?
Keyword density is the percentage of times a word or phrase appears relative to the total word count of your listing. It tells you how heavily your description leans on specific terms.
Ideal density: 2-5%
For your primary keywords, aim for a density of 2-5%. This signals relevance to the store's algorithm without reading unnaturally. Secondary keywords can sit around 1-2%.
Don't stuff keywords
Both Apple and Google penalise keyword stuffing. If your density for any term exceeds 8-10%, your listing may be flagged or demoted. Write for humans first, algorithms second.
Focus on the first 3 lines
Only the first few lines of your description are visible above the fold in both stores. Front-load your most important keywords there — most users never tap "Read more".
