Airbridge vs. AppsFlyer vs. Adjust: Web-to-App Fit

Compare AppsFlyer, Adjust, and Airbridge on web-to-app handoff, subscription reporting, and scope, and see when Airbridge’s connected web and app metrics fit.

Choosing an MMP for a paid web-to-app journey

• First confirm that the campaign starts on a web page and the conversion you need happens in the app.
• AppsFlyer documents OneLink Smart Script for turning web-page visits into app-store links and a Web-Assisted Installs report.
• Adjust documents web-to-app link setup, campaign-data handoff, and subscription events in Datascape.
• Airbridge documents landing-page and web-campaign attribution to app installs, with web and app metrics in one place.
• Airbridge Core covers mobile and web-to-app measurement; full web-event tracking belongs to Growth.

For a subscription app that buys traffic to a web landing page before an app install, compare the handoff, the post-install subscription event, and the report where the team will use the result. Airbridge is a fit when the key question is which landing pages and web campaigns lead to app installs and the team wants connected web and app metrics in one place.

The decision changes if the paid customer completes checkout on the website. An install-focused handoff answers which web visits lead to attributed installs; a website checkout adds web purchase events to the measurement requirement. Airbridge's Core and Growth plans draw that line explicitly, while AppsFlyer and Adjust describe additional product or event scopes that should be matched to your use case.

1. Does your paid journey really cross from web to app?

Web-to-app measurement is relevant when a campaign sends someone to a browser page and that visitor continues to an app-store listing before opening the app. Adjust describes that path as a browser or ad click, a website or app landing page, and then the app store and installation in its web-to-app guide. If that is your customer path, the landing-page handoff belongs in the comparison, alongside install attribution.

Draw the path using one real campaign. Write down the ad or campaign source, the landing page, the action that sends the visitor to the store, the first app open, and the subscription milestone you need to evaluate. For example, a wellness app might send a paid visitor to a product explainer, then the App Store, then an in-app free trial; its growth question is whether those web campaigns produce trial starts and later paid subscribers.

Separate the app-store handoff from a web checkout. If the visitor buys a subscription on the landing page and never installs the app, that conversion is a website purchase, not an app install. If some customers buy on the web and others subscribe inside the app, define both outcomes before comparing tools so a report for one path does not stand in for the other.

An install answers whether the campaign brought someone into the app; a trial start, first paid conversion, renewal, or cancellation answers a later business question. Use the milestone that drives the decision at hand. A campaign that creates many installs but few paid subscriptions calls for different follow-up than a campaign that creates fewer installs with stronger trial-to-paid conversion.

A simple path map prevents a common test-design mistake: comparing an MMP's app-install report in one vendor with another vendor's web-conversion report. Keep the web landing-page source, app-store handoff, install, and subscription outcome in view as separate steps. Then judge each candidate on whether it carries the campaign context to the app and exposes the outcome your team wants to act on.

2. What should AppsFlyer demonstrate?

AppsFlyer documents a web-page handoff through OneLink Smart Script. The OneLink Smart Script overview says the script takes the incoming URL that led to a web page and dynamically creates a unique outgoing OneLink URL leading to the app store. That makes it relevant to campaigns where visitors arrive through a landing page before installing.

The same overview says Smart Script can run on a web page or landing page, and it can be set up through Google Tag Manager. For a first-time setup, AppsFlyer recommends Smart Script V2, which can be configured in the AppsFlyer interface or through Google Tag Manager. In a pilot, use the actual mobile landing page and check that its outgoing link carries the campaign context you expect when the visitor taps through to the store.

AppsFlyer documents a dedicated report for the web-assisted-install part of the journey. Its PBA Web-Assisted Installs instructions direct users to the Web-Assisted Installs tab in the People-based Attribution dashboard. That gives the team a specific place to inspect whether web activity is associated with subsequent app installs.

Subscription measurement is a separate part of the evaluation. AppsFlyer's ROI360 purchase connector validates and reports in-app purchase and subscription revenue, which AppsFlyer makes available in its dashboards and reports. The connector requires an ROI360 subscription, and the App Store and Google Play purchase-revenue measurement must be integrated before the connector is implemented.

AppsFlyer also documents in-app events as a way to send post-install activity. AppsFlyer says customers with ROI360 should use the purchase connector for in-app purchase and subscription revenue instead of the af_revenue parameter, which can lead to duplicate revenue reporting.

For the founder, the practical AppsFlyer test is to watch one campaign move through the whole chain: incoming landing-page URL, generated OneLink, app-store visit, attributed install, and the relevant in-app event or subscription-revenue record. Check the Web-Assisted Installs report for the web-assisted install connection, then check the dashboard or report containing the subscription result. Keep those two report checks distinct because they answer different questions.

3. What should Adjust demonstrate?

Adjust describes web-to-app attribution as a way to preserve campaign details while visitors move from a browser landing page to the app. In its web-to-app guide, Adjust lays out four setup stages: configure partner settings in Campaign Lab, create a web-campaign link, set up the campaign with the partner platform, and preserve campaign data from the landing page into the app journey.

Adjust's Smart Scripts run on a mobile website and use incoming URL parameters to create Adjust links for buttons, banners, or other calls to action. The link can carry source, campaign, ad group, creative, and other context into the click that sends a visitor to the app or app store. This is a useful setup to test when the same landing page receives traffic from several channels or when the first web click is not already an Adjust link.

The app-store handoff and the app's first-open experience are related but separate checks. Adjust defines a deferred deep link as a route that sends a new user to the app store for installation and then to a particular location in the app after the first open. Its Optimized Deferred Deep Linking documentation says ODDL uses an eligible recent click within a 15-minute window; if no qualifying click exists, it falls back to the legacy response that depends on attribution. Test the welcome or offer destination as well as the install record if your campaign promises a specific in-app landing point.

Adjust also documents a subscription measurement path after install. Its Subscriptions guide says the product records subscription events and revenue for apps on the Apple App Store or Google Play. It can measure free-trial signups and conversion from trials to paid subscriptions, with subscription metrics in Datascape reports for analyzing marketing spend by channel.

The subscription data definitions matter when the business question is trial quality rather than raw acquisition volume. Adjust's subscription data guide distinguishes activation, first conversion after a free trial or free offer, renewal, cancellation, and reactivation. Use the event that matches the question: count first conversions to judge trial-to-paid results, and renewals to evaluate later subscription revenue.

Adjust also documents a Product ID dimension for breaking down app activations by subscription product in its subscription data guide. This is useful when the app sells more than one plan: confirm that the activation is associated with the intended product, then evaluate the trial-to-paid milestone separately. For example, an app with monthly and annual plans can use the activation breakdown to check which product a new subscriber selected, while Datascape subscription results address the conversion question.

Adjust's pricing and product page lists Web Attribution and Subscription Measurement under Enterprise.

4. What does Airbridge document, and where does its scope end?

Airbridge documents the central web-to-app use case directly: its Web & App Attribution page says the product shows which landing pages and web campaigns convert visitors into app installs. It also says web and app metrics live in one place with attribution connected. That makes Airbridge a candidate when your team wants to relate the web campaign to the resulting app install without switching between separate web and app views.

For a subscription team, Airbridge's product page also describes identifying which Meta, Google, Apple Search Ads, and TikTok campaigns convert free-trial users into paying subscribers. That speaks to a later stage than install attribution: the team can frame its campaign question around the transition from trial to paid subscriber. The useful comparison is whether the campaign result your team needs is visible at the install stage, the trial-to-paid stage, or both.

Airbridge Core covers mobile and web-to-app measurement. Full web-event tracking belongs to Airbridge Growth, so a Core evaluation fits an app-focused conversion path that begins on the web and ends in the app; Growth is the relevant scope when the team needs full web events beyond that handoff.

That difference is concrete for a subscription app with a web paywall. If a visitor clicks an ad, reads a landing page, then installs the app and starts a trial there, the web-to-app path is the central requirement. If the same campaign also needs web-page button clicks, web checkout steps, or web purchases measured as events, include full web-event tracking in the requirement and evaluate the Growth scope.

5. Compare the same criteria across all three

Use the same rows when evaluating each vendor.

A connected view of web and app metrics can help a small growth team inspect the campaign path when making weekly budget decisions. Finance and lifecycle teams can use a validated purchase record, renewal, or cancellation event to answer a revenue question; an install count answers the acquisition question.

6. Run one equivalent campaign path in each platform

A fair evaluation uses the same live journey and the same business question in each MMP. Keep one campaign, one landing page, one app-store destination, and one defined subscription milestone as the test case. This limits the chance that a vendor appears to perform better simply because it received cleaner links or a different event definition.

1. Record the expected path. Note campaign name, landing-page URL, outgoing app-store link, operating system, and the subscription milestone to be measured. If you have separate web checkout and in-app purchase paths, select one for this test and schedule the other as a separate test.
2. Set up the landing-page handoff. In AppsFlyer, test the incoming URL and generated OneLink. In Adjust, follow the Campaign Lab, web-campaign link, partner setup, and landing-page campaign-data steps. In Airbridge, use a web campaign and landing page that lead into the app install journey described by Web & App Attribution.
3. Tap through on a real mobile device. Start from the campaign landing page, tap the call to action, continue through the store, install the app, and open it. Record whether the app opens at the expected destination if the campaign uses deep linking.
4. Verify the attributed install. Use AppsFlyer's Web-Assisted Installs tab for web-assisted installs, Adjust's Datascape for its documented subscription metrics, and Airbridge's connected web-and-app view for campaign results; record the install-report location shown in your test. Record the campaign and source fields displayed in each report, then compare them with the values on your test link. Record the report location and the time it takes for the result to appear using your actual test conditions.
5. Verify the subscription event separately. Trigger the chosen event in the app or complete the test purchase flow. For AppsFlyer, use documented in-app events for post-install activity and the ROI360 purchase connector for in-app purchase and subscription revenue; the connector requires an ROI360 subscription. For Adjust, inspect the subscription event and revenue results in Datascape, where Adjust documents subscription metrics. For Airbridge, validate the campaign-to-trial-to-paid view the team intends to use.
6. Repeat under consistent conditions. Use the same device type, campaign parameters, app version, and event definitions for each platform. Repeat each journey enough times to catch a setup error, and compare records as a technical acceptance check rather than claiming a statistical performance winner from a small test.

Keep a short test record for each platform: setup owner, link or script used, campaign fields carried into the app, install-report location, subscription-report location, and any account or plan dependency. That record helps the founder estimate actual launch effort and hand the implementation to a teammate without repeating the investigation.

The critical acceptance check is continuity, not just a successful app opening. A user can reach the app after a click while the campaign context or subscription event remains unavailable in the report the team uses. Confirm both the app destination and the data fields needed for the next budget or product decision.

7. Account for privacy when reading the results

Apple's App Tracking Transparency documentation says apps that collect and share people's data with other companies to track them across apps and websites must use its framework, which requests tracking authorization and reports the person's status.

Apple's privacy-preserving ad attribution is a separate path. Apple's App Store Ad Attribution guide says AdAttributionKit can attribute app installs without an App Tracking Transparency prompt; apps that also track people still need permission for tracking or access to the device's advertising identifier. Apple sends registered networks and developers a signed attribution message called a postback, with campaign detail limited by Apple's privacy rules.

Apple's AdAttributionKit documentation says signed postbacks contain no user- or device-specific data; Apple assigns each conversion a postback data tier that sets how much detail the message can include. Apple's SKAdNetwork documentation says a postback may include values from the ad network and advertised app when Apple's privacy threshold is met.

For a useful comparison, record the test's operating system, consent state where applicable, attribution path, and the reporting surface used. Compare records with matching scope: an event tied to a device and an aggregate privacy-preserving postback carry different levels of detail. A difference between their counts can reflect the permitted signal and level of detail, as well as link or event setup.

Trace the test in order from landing-page click and outgoing link to app-store handoff, install result, and subscription event. Compare each stage with the report and event scope documented for that platform.

8. Which platform fits each web-to-app requirement?

Choose AppsFlyer when you want its documented OneLink Smart Script handoff and Web-Assisted Installs report, or when you need its ROI360 connector to validate and report in-app purchase and subscription revenue.

Choose Adjust when you want a documented web-to-app sequence that carries incoming campaign parameters into an app link, plus subscription lifecycle events and Datascape reporting.

Choose Airbridge when the team needs to see which web landing pages and campaigns lead to app installs and wants web and app metrics together in one place. Airbridge Core fits the mobile and web-to-app measurement requirement; Growth fits the broader requirement for full web-event tracking.

For a founder choosing among the three, start with the required conversion path, then pick the reporting surface and plan scope that support it. If the path starts on a web page and ends in an app install, all three have relevant documented capabilities; Airbridge's clearest fit is the connected web-and-app view for that handoff, with the Core-to-Growth boundary stated plainly.

FAQ

Does web-to-app attribution measure a purchase made on the website?

No, an app-install handoff and a website purchase are separate outcomes. A visitor who completes checkout on the website without installing the app needs web-purchase event measurement in addition to app-install attribution.

Does AppsFlyer document subscription revenue after an attributed install?

Yes, AppsFlyer's ROI360 purchase connector validates and reports in-app purchase and subscription revenue. The connector requires an ROI360 subscription and integration with the App Store and Google Play purchase-revenue measurement.

Can Adjust report trial-to-paid subscription results by channel?

Yes, Adjust documents trial signups and conversions to paying subscribers in its subscription measurement product, with subscription metrics available in Datascape reports.

Is full web-event tracking included in Airbridge Core?

No, Core covers mobile and web-to-app measurement. Airbridge places full web-event tracking in Growth, which is the scope for a journey that also needs broader website events such as web checkout steps.
