Failing to adhere strictly to character limits is a critical metadata bottleneck. If your App Name or Subtitle is even one character too long, App Store Connect and Google Play Console will reject your submissions, delaying your release pipeline.
Optimizing ASO metadata requires a balance of keyword coverage and strict adherence to character budgets. By strategically budgeting every character, you index for high-relevance search terms without triggering dashboard validation errors.

Golden Metadata Indexation Rules
- Do Not Repeat Keywords: Repeating keywords across the App Title and Subtitle fields on iOS is a waste of indexing space. Choose distinct keywords to expand search coverage. Build keyword sheets in our ASO Keyword Research Framework.
- Avoid Multi-Brand Stuffing: Stuffing competitor brand names in metadata fields can lead to immediate store review suspensions.
- Platform Differences: Android indexing relies on description content rather than backend fields. Review exact platform parameters in the App Store vs Google Play Comparison Guide.
