65% Of app discovery on iOS happens through App Store search Store search is by far the largest discovery channel on iOS, ahead of browse (18%), referrals (12%) and ads (5%). If you can't be found on the right search terms, you don't exist for those users. Source: Sensor Tower (State of ASO) (2026)
58% Of app discovery on Google Play happens through store search On Android too, store search is the most important acquisition channel. Your position in search results determines whether people find and install your app, not your website. Source: Sensor Tower (State of ASO) (2026)
33,4% Median conversion rate from store page to install in the App Store Only a portion of visitors actually install. Strong screenshots, title and description are the lever to raise that conversion. Source: AppTweak (2026)
27,7% Median conversion rate from store page to install on Google Play The App Store converts on average slightly higher than Play, but the differences per category are enormous. Source: AppTweak (2026)
+89% Higher conversion when an app goes from 3 to 4 stars Ratings and reviews weigh into both the ranking and the user's choice. It's the most underrated ASO lever. Source: AppsFlyer (2024)
~4 mln Apps combined in the App Store and Google Play The stores are packed, with roughly 3.5 million apps on Google Play and 1.8 million in the App Store. Without targeted optimization, an app simply disappears into the crowd. Source: Statista (2026)

What do these figures mean for Belgian B2B companies?

The figures show that ASO is a genuine discipline: store search determines discoverability, ratings drive both ranking and conversion, and retention determines whether it was all worth it. But they also show something else. ASO only pays off once an app is central to your model. For a B2B SaaS with a mobile app, or a platform people use daily, it’s a serious lever.

For most Belgian B2B service providers, that isn’t the case. If you don’t have an app, your target audience searches for you via Google, not via the App Store. Your budget is then better spent on technical SEO and strong content that reaches the right decision makers. And if you do have an app, don’t forget the mobile landing page: most visitors arrive on a phone. Our advice stays the same: steer on customers and revenue, not on download counts that don’t deliver anything on their own.

Frequently asked questions

Is ASO relevant for B2B companies? +

Only if an app is genuinely central to your model, for example a B2B SaaS with a mobile app or a platform used daily. For most Belgian B2B service providers that don't offer an app, classic SEO and content marketing deliver more. Be honest about where your target audience actually searches.

What matters more: more installs or better ratings? +

Both are connected. Ratings and reviews weigh into both the store ranking and the user's decision, so a higher rating often boosts your conversion and your discoverability. Taking an app from 3 to 4 stars can raise conversion by almost 90 percent.

Do raw download numbers count as success? +

Not without retention. An install that disappears after a day costs money without delivering anything. Steer on active users and, in B2B, on users who actually become customers, not on download counts.
