App store optimisation: getting found and getting installed

Store listings are a search and conversion problem. Most of the available improvement is in the first screenful.

Key takeaways

  • Title and subtitle are the most heavily indexed fields.
  • The first two screenshots carry most of the conversion.
  • Ratings drive both ranking and conversion — ask at the right moment.
  • Measure installs through to retention, not installs alone.

Title and subtitle carry the most weight

The app name and subtitle are the strongest indexed fields in both stores. They should contain the terms people actually search for, phrased naturally rather than stuffed.

Research what your audience types rather than what you call the product internally. Category jargon is a common trap: people search for what the product does for them.

Screenshots decide the install

Most visitors judge from the first two screenshots without scrolling. Lead with the single clearest benefit, use captions rather than bare device frames, and show the product doing something recognisable.

  • Design for the small preview size, not full screen.
  • Put the strongest value proposition first.
  • Localise screenshots for major markets.
  • Update them when the interface changes — stale screenshots erode trust.

Ratings and reviews compound

Rating is both a ranking factor and the strongest conversion signal on the page. Prompt for review after a moment of success rather than at launch, and never interrupt a task to ask.

Respond to negative reviews. It frequently converts a one-star into a higher rating, and it demonstrates to other readers that the product is maintained.

Iterate with the tools provided

Both stores expose install funnel data and support experimentation on listing assets. Test one element at a time — icon, first screenshot, subtitle — and give each enough traffic to be meaningful.

Track installs to retention, not just installs. A listing that overstates the product produces installs that churn immediately, which helps nobody.

Measuring what the listing actually does

Listing changes are easy to make and easy to misattribute. Both stores provide conversion data from impression to install, which is the measure to watch rather than install count, since that also moves with marketing spend.

Change one element at a time and give it enough traffic to be meaningful. Changing the icon, screenshots and subtitle together tells you the combination worked, not which part.

Then follow installs through to retention. A listing that overpromises lifts installs and depresses retention, which is worse than no change at all.


Frequently asked questions

Refresh screenshots whenever the interface changes materially, and revisit keywords a few times a year as search behaviour shifts.

On the App Store the description is not indexed for search, though it affects conversion. On Google Play it contributes to indexing. Write for people first in both cases.

For markets that represent meaningful volume, yes. Localised titles, keywords and screenshots typically improve both visibility and conversion more than translating the app alone.
