A deep link is a link that goes directly to a specific piece of content within your app. Without deep links, people have to search through your app for the content they are looking for. With deep linking, you send people directly to information they are interested in when they open your app for the first time.
Because the first landing point in your app is related to the idea that motivated a person to tap the ad, they are more likely to engage with the content of your app.
Deep Link Example
Before you can use deep linking, you need the following:
On iOS, deep linking works only with ads. As a result, you can't use deep linking with other things, like app invites.
You must enable Advertiser ID collection for deferred deep linking to work.
