If you're running any YT or Display campaigns - then you 100% want to exclude your ads from showing on Mobile Apps.
The majority of the time they will waste money and not convert (unless you are advertising another mobile app).
Google makes this tricky, but if you want to 100% exclude mobile apps without needing to individually add them inside the Google Ads interface then you can easily do this in 1 minute inside of Google Ads Editor.
I was working with one of our analysts here at Grow My Ads and I walked him through how to do this and thankfully had the call recorded so I figured I'd share with you guys here.
Hope you get some value from it!
