The Zero-Repeat Keyword Strategy for App Store Metadata
Why repeating words across your Title, Subtitle, and Keyword field harms your rank
The Myth of Keyword Density in App Store Search
Many developers accustomed to web SEO believe repeating a keyword multiple times increases keyword density and relevance. On the App Store, this is completely false.
Apple's indexing engine treats each unique word as a binary presence in your metadata set. Repeating 'fitness' in your Title, Subtitle, and Keyword field gives zero extra ranking weight.
By repeating words, you forfeit 10 to 30 characters that could be used to index 3 to 5 additional root keywords.
How to Apply the Zero-Repeat Rule
Place your highest-demand core keywords in the App Title (e.g., 'Brand: Running Tracker').
Use the Subtitle for completely new secondary terms (e.g., '5K Marathon Pace & GPS Map').
Ensure every word in the 100-character keyword field has never appeared in either the Title or Subtitle.

Frequently asked questions
- Does repeating a keyword in Title and Subtitle increase its ranking weight?
- No. Apple indexes each word once. The position matters (Title has more weight than Subtitle), but repeating it across both does not boost your rank.
- How many total unique keywords can I fit with the Zero-Repeat Strategy?
- A well-optimized metadata set can index 20 to 25 unique root words, which combine to form hundreds of searchable long-tail keyword combinations.
