Google Not Indexing App Content

[InMarketingWeTrust]

Hello Mozzers

I recently noticed that there has been an increase in crawl errors reported in Google Search console & Google has stopped indexing our app content. Could this be due to the fact that there is a mismatch between the host path name mentioned within the android deeplink (within the alternate tag) and the actual URL of the page.

For instance on the following desktop page http://www.example.com.au/page-1 the android deeplink points to http://www.example.com.au/android-app://com.example/http/www.example.com.au/4652374

Please note that the content on both pages (desktop & android) is same.Is this is a correct setup or am I doing something wrong here? Any help would be much appreciated. Thank you so much in advance.

Yes - 301 to destination could be the problem. Can you do test w/o redirects putting end URL into rel=alternate?

Also you must check correct linking from Android to web:
https://developers.google.com/app-indexing/android/app

In ideal linking both must be linked vice versa. Probably one of linking now is broken as far as we see.

Thank you for your feedback Peter. My apologies, I made a mistake in the question description. The rel=alternate is exactly as you mentioned:

I did use Fetch and Render tool and Google renders is property. However on a side note, the URL http://www.example.com.au/4652374 301 redirects to http://www.example.com.au/page-1. Could this be as issue as I am not using the final destination URL within the android deep link?

Thank you so much in advance.

There is bug on rel=alternate. It should be as:

only.

Anyway - get this URL and try in your SearchConsole to "Fetch and Render" probably this will help you fixing your web error.
