A store listing is a landing page with unusually brutal character limits and an unusually distracted audience. Most people arriving at it have already looked at three competitors. This is how to make the limited space count.
Understand what each field is for
The fields are not interchangeable, and treating them as one undifferentiated block of keywords is the most common mistake.
- Title (30 characters, both stores). Carries the most ranking weight and is the only text guaranteed to be visible everywhere. Your brand plus one strong descriptor.
- Subtitle (30 characters, App Store). Second most weighted. Use it for the benefit your title could not fit.
- Short description (80 characters, Play). Appears above the fold. Play weights it for ranking, and it is often the only sentence a user reads.
- Keywords field (100 characters, App Store only). Never displayed. Pure ranking input.
- Long description (4000 characters, both). Play indexes it for search; Apple does not. On Apple it is persuasion only.
Because Apple does not index its long description, stuffing keywords there achieves nothing except making it harder to read. On Play, the same text genuinely affects ranking — so the optimal long description is written differently for each store.
Lead with the outcome, not the mechanism
"Track habits with streaks and reminders" describes machinery. "Never break a good habit again" describes a result. Outcomes convert better because they answer the only question a browsing user is actually asking: what changes for me if I install this?
A reliable way to find your outcome sentence is to finish this line honestly: *After using this app for a week, I will be able to ___.* If the blank contains a feature name, keep going until it contains a change in the user's life.
Feature-led copy still has a place further down, for users who have already decided they want this category and are now comparing implementations.
Use the keywords field properly
Three rules recover most of the wasted space in a typical Apple keywords field:
- Do not repeat words already in your title or subtitle. Apple indexes those too, so duplicates are wasted characters.
- Use commas with no spaces. "habit,tracker,streak" fits more than "habit, tracker, streak".
- Skip plurals and the word "app". Apple handles basic stemming, and "app" is implied by the entire context.
Multi-word phrases are generally matched from the individual words you supply, so you rarely need to spend characters on both "habit" and "habits", or on a phrase whose words already appear separately.
Screenshot captions are copy, not decoration
The first two screenshots are visible without scrolling in search results and drive a large share of installs. They deserve the same attention as the title.
- One idea per screen. A screen that makes two points usually makes neither.
- Seven words or fewer per headline. Longer headlines get read as paragraphs, which means skipped.
- Concrete beats clever. "Split any bill in two taps" outperforms "Bill-splitting, reimagined" because it is checkable.
- Lead with the strongest, not the chronological first. Nobody needs your onboarding screen first.
- Make the first two work as a pair. They are seen together, so do not spend both on the same claim.
Write three versions, then test
Strong listing copy is rarely first-draft work. A practical approach is to write three deliberately different variants — benefit-led, feature-led, and a plainer factual one — then run them through each store's native experiment tooling: Product Page Optimization on Apple, Store Listing Experiments on Play.
Test one variable at a time. Changing the title and the screenshots together tells you that something changed, not what.
Localisation is usually worth more than another keyword
Translating your listing into even three or four additional languages typically moves more installs than another round of keyword tuning in English, because it opens markets where you currently rank nowhere at all.
Machine translation is an acceptable first pass, with two caveats. Get the title and the first two screenshot captions reviewed by a human speaker, since those carry the most weight and are the most damaging to get wrong. And re-check character limits, because translations commonly run 20 to 30 percent longer than English.
A checklist before you publish
- Title under 30 characters, containing your single most valuable keyword phrase. - Subtitle covering a different benefit from the title, not a restatement. - Keywords field with no duplicates, no spaces after commas, no plurals. - First two screenshots each carrying one benefit-led headline under seven words. - Long description written twice: keyword-aware for Play, persuasion-first for Apple. - Every field checked against its limit inside the store's own preview, not your text editor.
