Uses and main types of mobile app deep links
Understand this event
On October 12, 2026, PPC Land published an article in its Advertising and Platform News section introducing the uses and main technical types of deep links. The article says deep links can open specific content directly within a mobile app, such as a product page, playlist, or booking page, instead of taking users to the app’s home screen or an app store page. Technically, deep links fall mainly into three categories: custom URI schemes, Apple Universal Links, and Android App Links. Deferred deep links address the scenario in which a user has not yet installed the app. The article provided here covers only these functions and categories.

What happened
PPC Land published a technical explainer on deep linking on October 11, 2026; it is not an announcement of new rules. Deep links can open pages such as product listings directly within an app, but actual redirects depend on the operating system, installation status, and click source. The article says Firebase Dynamic Links was discontinued on August 25, 2025, and old links return 404; it does not specify which countries are covered. [1]

Seller impact
- InferenceFor advertisers with their own apps, reducing the steps after a click may improve conversion, but this does not justify assuming better ad returns. The article’s twofold and 2.8-fold conversion figures come from a tool vendor that did not disclose its methodology, so they cannot be applied directly. [1]
- InferenceRedirects and attribution may become bottlenecks in ad campaigns: the article says Google App Connect does not support third-party redirect links. A vendor report also says that social media in-app browsers block app redirects; the specific channels still need to be tested. [1]
Suggested action
If you are running app ads, spot-check one active link across installed, uninstalled, and in-app browser scenarios, including its destination page and attribution results.
Evidence that would disprove the assessment
- Assessment 1：For the next two weeks, run a controlled test with the same channel and audience. If the app landing-page conversion rate does not improve, the expected benefit is not supported.
- Assessment 2：If current official documentation confirms support for the relevant redirects, and channel testing shows that the destination page opens reliably while preserving attribution, this assessment of the limitation should be revised.

A deep link is a link that opens specific content directly within a mobile app, such as a product page, playlist, or booking page, instead of landing on the home screen or an app store page. The three main technical types are custom URI schemes, Apple Universal Links, and Android App Links. Deferred deep links also address the scenario where the app is not installed.
