Deep Links vs Campaign Tracking: Google Ads Route Guide

Deep links vs campaign tracking are separate jobs: the campaign destination routes a click, while an MMP connects ad interactions to installs or app events. Airbridge publishes this guide for growth and product teams choosing a Google Ads route and a way to measure the campaign. For a subscription app, that separation lets you send an existing subscriber to the right in-app screen while measuring new attributed installs and events.

Do deep-link routing and campaign tracking need the same tool?

No. Deep-link routing and campaign attribution can use different tools, because they answer different questions. A deep link chooses the content or screen a click should open; attribution connects an install or app event with an ad interaction under the measurement partner’s rules.

The app’s installed state changes the route. If the app is installed, an app link can open the relevant page directly, such as a plan comparison or a saved workout.

Attribution is a separate connection between the ad platform, the app, and the measurement provider. It can record an install or later event such as trial start or paid subscription, depending on the app’s configured events and the provider’s integration. A useful setup therefore names both things clearly: the URL that delivers the user, and the measurement integration that reports campaign results.

That distinction matters when a founder is debugging a campaign that spent money without a new subscriber. Test and review these outcomes separately.

Google Ads deep linking: which destination URL should you use?

Choose the final destination by campaign type and operating system. Google Ads’ deep-link setup instructions describe app-campaign routes for Android and iOS, while the campaign setup field determines where you enter the link. A native app link is the user-facing destination; an MMP’s measurement configuration is a separate step.

A Universal Link associates an HTTPS URL with an app and opens that app when clicked if it is installed, as described in AppsFlyer’s deep-link guide.

An installed user can land on the trial or offer details promised by the ad. For Android App campaigns for installs, Google instructs teams to enable deferred deep links in the app measurement SDK. Test a real campaign click for the intended destination; for an iOS Universal Link, clicking a link can open the app when installed, while pasting it into Safari’s address bar does not test app opening, as explained in AppsFlyer’s Universal Links guide.

Can an MMP measure Google Ads when the final URL is a native app link?

Yes. Adjust’s Google Ads setup guide says attribution comes through partner APIs, so a tracking link is not needed to measure those campaigns.

Before comparing providers, use the same three criteria for each setup: Does its Google Ads integration cover the campaign and the installs or in-app events you use? Does the destination match the campaign type and operating system? Does the link journey serve both people who already have the app and people who install after the click? A combined platform can cover measurement and deferred linking, while the campaign destination still follows Google Ads’ route rules.

Adjust’s Google Ads setup guide says representative links are created automatically once measurement starts. For Google Ads web-to-app campaigns, Adjust recommends generating Adjust links when Google Ads might not claim attribution for certain users, allowing Adjust to use those links for attribution.

AppsFlyer’s Google Ads integration measures and attributes installs and in-app events. For deferred deep linking, AppsFlyer supports Google feed or ad-group links; its setup uses GCD to pass the af_dp parameter to the SDK and enables the deferred-deep-link setting in the Google Ads integration. To see installs in AppsFlyer, import app conversions; mapped in-app events use the event setup in that integration.

Branch’s Google Ads guide separates destination and attribution in its supported web engagement flow: an iOS Universal Link or Android App Link goes in Final URL to open the app, and a Branch Link goes in Tracking Template for Branch attribution. Branch Links are unsupported for App Engagement campaigns, which use platform links or a custom URI scheme, and App Install campaigns, which use Branch SAN Deferred Deep Linking for deep links.

Choose an existing MMP, a combined platform, or a separate link tool

For an existing MMP, keep the working measurement connection if it already reports the events you use to make subscription decisions. Add or adjust the deep-link route only where the current destination fails the campaign’s user journey. If trial starts and paid subscriptions drive decisions, confirm those events are mapped and arrive in the relevant reporting view before judging a campaign by installs alone.

A separate link tool adds another configuration surface. Before adding one, assign ownership for the domain, link rules, and fallback behavior so the team knows where to investigate a broken route.

What to test before launch

Run these checks in order. The aim is to verify the user journey and measurement independently, so a successful click does not hide an event-mapping problem and an attributed install does not hide a broken destination.

1. Write down the campaign and user states. Record whether the campaign is an App Install, App Engagement, or another campaign type, and whether the person has iOS or Android and already has the app installed. That list determines which Google Ads URL guidance and MMP setup apply.
2. Set the destination field for that flow. For Android App campaigns for installs, use an Android App Link or supported custom scheme; for iOS App campaigns for installs, Google’s app-specific URL directs existing app users to the in-app page and users without the app to the default app-store page. In a Branch flow, keep the native destination in Final URL and configure the Branch Link in Tracking Template when the campaign setup supports it.
3. Validate the platform association. On Android, make sure the web domain is associated with the correct app and paths. Airbridge’s Android App Links setup guide points to Google’s Statement List Generator and Tester, which checks whether assetlinks.json is reachable, valid JSON, and matches the app package name and fingerprint. On iOS, verify that the app and domain have the association required for Universal Links before testing a campaign click.
4. Confirm the MMP integration and event mapping. Verify that Google Ads is enabled as a partner where the MMP requires activation, then check that the install and the in-app events you care about are mapped. In AppsFlyer, launch the app and perform each mapped in-app event at least once so Google Ads can register those conversions.
5. Test both install states on real campaign routes. Click through with the app installed and confirm the intended screen opens. Then test an install journey and confirm the first app open reaches the intended content where deferred deep linking is configured. Test the destination in the same platform and campaign flow you plan to run; for an iOS Universal Link, do not rely on pasting the URL into Safari’s address bar to test app opening.
6. Check measurement after the test events arrive. Look for the attributed install and mapped subscription events in the MMP, then verify the corresponding conversion setup in Google Ads. Compare event names and timing across the two reports before using the results to change bids, creative, or trial offers.

If the app opens to the home screen instead of the ad-promised page, troubleshoot the route and deferred-link handoff first. If the screen is correct but attributed installs or trial events do not appear, check the MMP integration and event mapping. Keeping those two checks separate tells your developer whether the issue belongs to the destination path or the measurement connection.

For a small team, the launch decision is straightforward: use Google Ads’ supported destination for the campaign, keep attribution in the provider whose integration covers that campaign, and add a separate link tool only for a routing need your current setup does not meet. Airbridge Core is one documented combined option for Google Ads attribution and deferred deep links, with SAN measurement that uses Google-provided identifiers instead of tracking links.
