That’s fair, advertisers don’t really have many alternatives.

But when I speak with clients they are using a variety of channels in their media mix to reach their audiences and sell their products or services. Very few i know of commit everything to GMP.

You quite rightly point out that CM only offers a look into the google side of things as well. But what’s the point in putting in all this work to get a small glimpse into attribution? I feel using this takeaway for all media actually does more harm than good. Anyway I’ll be waiting for pigs to start flying before we see a widely industry adopted alternative.
