I want to promote a popular mobile app on android through mobile display. I checked similarweb and found that search traffic accounts for 50% of all traffic, social accounts for 15%, and direct traffic through google play accounts for 20%. Mobile Display only accounts for 0.5%. From my own experience, this makes sense because I'd rather search on google than click on some suspicious banners. So, I suppose that is common for other app installs. What's the point of promoting apps through mobile display when it only brings in 0.5% of all traffic?
Those numbers might just mean that no-one or almost no-one has run a campaign promoting that app on mobile display yet!
What Caurmen said, plus one more thing.
You have to realize what the traffic distribution across various ad networks looks like.
Take a look at the image below :

Im not sure how accurate the data is, but lets assume it is. So google's ad network controls 85% of all traffic you can buy. Their search will be a large portion of it, and Im sure many spytools will simply mark anything with "google" in the url as SEARCH. So that might be the reason for the high search %.
Anyways, look at the other networks in the list, even such a huge network as exoclick does only have a market share of 0.4% !!! And they server 5.000.000.000 ad impressions per day. According to your findings, mobile display accounts for 0.5%, so thats more than exoclick
Doesnt look all that bad to me, right?
NOTE: I realize I reaaaaaly simplified this comparison. Just wanted to show how huge google really is and that a small % can actually account for a mega amount of traffic.
That explains a lot. Thanks.
