ASO vs SEO: what app store SEO really is

Quick answer: App store SEO, or ASO, is search optimization inside the App Store and Google Play. Unlike web SEO, there are no backlinks, character limits are tiny, and installs, ratings and conversion carry much of the weight. Your website still helps: app pages can rank on Google and send people to your listing.

How to run ASO and SEO together

Follow these steps in order. Each one is something we do on client work.

  1. Share keyword research. Search terms people use on Google often overlap with store searches.
  2. Give each page one job. Website pages answer questions; store pages convert.
  3. Link the website to the store. Use clear App Store and Play badges on relevant pages.
  4. Remember the description is indexed on the web. Apple says it's used for web engine results after release.
  5. Measure separately. App Analytics and Play Console for stores; Search Console for the site.
  6. Review monthly. Move winning phrases between channels.

Worked example (hypothetical)

This example is illustrative. The app is made up, and so are any numbers in it.

Say PlantPal ranks on Google for "why are my monstera leaves yellow". That page can link to the app's diagnosis feature with a store badge, while the store subtitle targets "plant care reminders". Same audience, two different jobs.

Common mistakes

  • Copying web copy into the store. Store fields have strict limits.
  • Treating Play like the App Store. Play has no keyword field.
  • No website at all. You lose web search entirely.
  • One metric for both. Measure each channel.

App Store vs Google Play: where your words go

The two stores index different fields. This is the comparison we use when we plan a listing for both.

Second lineSubtitle, 30 charactersShort description, 80 characters
Hidden keywordsKeyword field, 100 bytesNone; the visible text does the work

How we measure the result

Here is how we judge whether App Store SEO work is paying off. App Analytics in App Store Connect breaks impressions and product page views down by source, and App Store Search is one of those sources. On Google Play, the store performance and acquisition reports in Play Console show where visitors came from and how many of them installed.
