Google will now have AMP trump App URLs in the Google portable query items. That implies if a site has both AMP URLs empowered furthermore has a portable application with Firebase App Indexing (in the past Google App Indexing), Google will demonstrate the client, regardless of the fact that they downloaded your application, the AMP URL over the profound connection to the page inside your application.
Google discreetly posted this in their information peculiarities page, where they composed:
List items on cell phones have started to direct clients to the proportionate AMP page, in inclination to the equal application or site page. This may bring about a reduction of movement to your application pages when a comparable AMP page exists.
Google’s John Mueller affirmed this for me on Twitter saying, “Yes, right now if an AMP exists for a given URL then we will send the client to that AMP not the profound connection.”
Once more, if your site guest downloaded your application and you conveyed Firebase App Indexing, yesterday, Google would have sent the client to your application. Presently, since AMP is taking off to the center Google versatile indexed lists, that client will be taken to the AMP URL.
