How to Choose Keywords for an iOS App

A practical low-competition keyword model

Evaluate every candidate on three axes: relevance, observed competition and strategic value. Relevance should be a hard gate. Then inspect the U.S. result set: are the top apps dominant brands, do they have enormous rating counts, and do the results closely match the query?

Next, ask whether ranking for the term would matter. A tiny phrase with no buying or usage intent may be easy but worthless. A narrower problem phrase can be more valuable because the user knows exactly what they want.

Store candidates in tiers: core terms, realistic long tails, experimental terms and rejected terms. This makes future metadata changes explainable.

Step-by-step: How to Choose Keywords for an iOS App

1. Start with the user's job, not synonyms for your category.

Use the category that best matches the primary job. Then inspect the apps users will see around yours so you understand the visual and credibility bar. Category selection is context, not a substitute for relevant metadata.

2. Use title and subtitle space for high-value language.

Use this “how to choose keywords for ios app” step as a measurable checkpoint: record the current state, the expected outcome and the evidence you will review before expanding the work.

3. Reserve the keyword field for relevant non-duplicative terms.

For “how to choose keywords for ios app,” use the U.S. storefront consistently and save the exact query, date and result set. Relevance is the first filter; after that, compare brand strength, ratings and result quality to judge whether the term is realistically contestable.

4. Validate combinations instead of judging words in isolation.

Turn the statement into a falsifiable hypothesis. Ask what observable behavior would support it—searching, switching, joining a waitlist, completing a prototype task or paying—and what result would cause you to narrow or stop the project.
