App Store optimization: a practical guide for growing an iOS app

Start with the problem, not a bag of keywords

Write down who your app helps, the situation in which they need it, and the outcome they can reach. A task planner for rotating shift workers and a shared family calendar may both live in Productivity, but they compete for different intentions. If your description could fit either app, the positioning is too broad.

Use that statement to build a small research set. Include the main task, a narrower use case, and the language people use in support requests or interviews. Do not equate the presence of a suggestion in autocomplete with a known number of searches. Suggestions are candidate language, not a demand forecast.

Build a baseline before changing the listing

Record the current name, subtitle, screenshots, release date, selected storefront, and sampled keyword positions. In your own App Store Connect account, record the relevant acquisition and conversion metrics with their filters. Back My Side does not read those private analytics; the public report is a complementary view.

Keep the baseline definition stable. Comparing a worldwide total this month with US search traffic last month answers no useful question. Search-source reporting can include Apple Ads activity, so annotate paid campaigns rather than calling every search download organic.

Make the keyword promise visible

Your strongest relevant idea should be easy to recognize in the name or subtitle and supported by the first useful screenshot. Apple allows up to 30 characters for the name and 30 for the subtitle. The private keyword field has a separate 100-character budget. Those are constraints for clear writing, not targets to fill with unrelated phrases.

Make sure the product can fulfill the promise without a surprise. An app targeting offline note taking should show the offline workflow and disclose any limits. Better visibility for the wrong promise can create disappointed users, weak retention, and avoidable support work.

• Audit metadata for relevance, duplication, and unauthorized names.
• Show a real product action rather than a vague benefit claim.
• Explain important subscription or feature limitations accurately.

Run one interpretable improvement cycle

Pick the bottleneck with the clearest evidence. If the app is found for relevant searches but visitors do not download, investigate the product page. If discovery is weak, review keyword fit and storefront availability first. If users download and immediately abandon the app, acquisition is not the only problem to solve.

Document the hypothesis, change, release time, and review window before shipping. Use Apple’s product page optimization for eligible creative tests; it does not randomize keyword-field or title changes. Observing growth after a metadata update is useful, but seasonality, campaigns, competitors, and product improvements can also explain it.

End the cycle with a decision: keep, revise, roll back, or collect more evidence. A short record of what you learned is more valuable than a dashboard full of unsupported explanations.
