Key features

  • Deep linking: Use deep links to send mobile device users directly to relevant pages in your app rather than your website. People who click on your ads can go directly to the app pages you specify.
  • Conversion tracking: Measure what happens after a user clicks on your ads and lands in your app, like whether they purchased a product, signed up for an account, called your business, or subscribed to your newsletter. When a user completes an action that you've defined as valuable, these user actions are called conversions .
  • Bidding: Select the in-app conversion actions that you want to optimize for using your web campaigns. You may improve your ad campaign performance by using Smart Bidding , which automatically drives higher performance for your business goals, like maximizing conversions or conversion value.

Web to App Connect tracks your app conversions and measures their value using GA for Firebase and AAP, boosts campaign performance by using Smart Bidding, and helps you deep link to drive users to the app, using app links and universal links.


About conversion tracking and bidding setup

To optimize your app campaigns for maximum conversions and value, focus on these key areas:

  • Link your accounts: Implement your app's measurement SDK and link it to your Google Ads account to enable data flow.
  • Define and import your conversions: Identify your most valuable in-app actions, such as purchases or sign-ups, and import them into Google Ads.
  • Prioritize your conversions: Designate your important conversions as "Primary" to guide Smart Bidding effectively.
  • Adopt Smart Bidding: Leverage Smart Bidding strategies to automatically optimize key in-app conversion actions.

Performance overview

The performance overview will include the following data:

  • In-app conversion rate: It shows how often, on average, an ad click directed to your app leads to a conversion. It’s “in-app conversions” divided by the interactions with your ad landing in your app.
    • Note: App installs and first open conversion actions aren’t included as “in-app conversions”.
  • Web conversion rate: It shows how often, on average, an ad click directed to your website leads to a conversion. It’s “web conversions” divided by the interactions with your ad landing on your website.
  • All missed conversions: These indicate the aggregate potential performance uplift you'll get in terms of additional in-app conversions by implementing your non-deep linked URLs as App Links and Universal Links. Use these as a measure of your missed opportunity. Implement deep links to better capture these conversions.
  • Deep link coverage: This measures the proportion of your current mobile spend flows through deep links and into your apps. The higher the deep link coverage, the larger the number of users who are directed to your mobile app, which provides a much better user experience and ROI compared to relying only on your mobile website.
  • App bidding coverage: This measures the proportion of your current mobile spend that is associated with campaigns bidding on in-app conversions. The higher your app bidding coverage, the greater the opportunity to convert with valuable in-app conversion actions, so you can optimize campaign performance to maximize conversions or conversion value.
