When will the application receive a install_referrer with content utm_source=(not%20set)&utm_medium=(not%20set)?

Question

I'm using instll_referrrer tracking the user installation. Recently, I found a lot of user send the refer utm_source=(not%20set)&utm_medium=(not%20set) to my server.

I searched this on Google, and find a artical https://plus.google.com/+AndroidDevelopers/posts/E54ae9beKLB which tell me this will be set as default for user from deeplinks. And then I searched the definition of deeplink but I don't quite understand it.

From now on, if there is no referrer parameter in the URL, a default will be set to separate organic installs from deeplinks (i.e. a third party referral to your Play Store listing).

Dose this means if I received some install_referrer with content content utm_source=(not%20set)&utm_medium=(not%20set),the user who sent these referrer have installed my app by third party referral which has a format like {scheme}://{host_path} ?

Answer 1

Google play store checks all the mail accounts which are logged into Google play and if you are logged in with work email (enterprise domain email id)it sets the UTM property as utm_source=(not%20set)&utm_medium=(not%20set).

So try removing work email from google play store and verify.

Use Google Play URL Builder to generate campaign URL.

It's worked for me

Answer 2

Your URL needs to have a "referrer" parameter, and encode your referrer in there. An example is

https://play.google.com/store/apps/details?id=a&referrer=utm_source%3Dgoogle%26utm_medium%3Dcpc%26anid%3Dadmob

You can try to use this https://developers.google.com/analytics/devguides/collection/android/v4/campaigns to create examples.

The documentation states that it only occurs when you use the deeplink (http) to the play store:

For a deep link into Google Play where the referrer parameter is not present or empty, the referrer value provided is:

utm_source=(not%20set)&utm_medium=(not%20set)

For instance:

https://play.google.com/store/apps/details?id=com.google.android.apps.maps
