app-store-optimization

App title optimization places high-priority keywords early in the title while staying within Apple's 30-character or Google Play's 50-character limit. The metadata_optimizer module generates multiple title options and validates character counts automatically.

Keyword research analyzes search volume estimates, competition level, and relevance for your app category and target audience. The keyword_analyzer module also finds long-tail keyword opportunities and extracts keywords competitors are using.

Apple allows 30 characters for title and subtitle, 170 for promotional text, 4000 for description, and 100 for the keyword field. Google Play allows 50 characters for title, 80 for short description, and 4000 for full description with no separate keyword field.

Required sample size depends on your baseline conversion rate and minimum detectable effect, typically thousands of visitors per variant at 90% confidence. The ab_test_planner module calculates exact sample sizes and estimates test duration for low, medium, and high traffic scenarios.

Keyword search volumes are estimates since Apple and Google publish no official data, and store algorithms are proprietary and change without notice. This skill also excludes paid user acquisition like Apple Search Ads and does not cover in-app analytics implementation.
