Hey guys,
Need your expertise. I'm running a sweeps mobile campaign. After running some data and isolating my best lander and offer through statistical split-testing, here's what I see on browser level for that specific combination:

I've naturally cut out Android Webview, and then my campaign overall CTR plummeted to 0.16%. It seems that blacklist also impacted the CTR of other browsers. From 0.61% and 18% ROI, Chrome mobile has dropped to 0.09% CTR and -46% ROI.
I'm assuming there is something wrong with the display of my pre-lander... but do you guys have any indications as to why Webview would behave so differently? It is my best converting lander, so I'm a bit hesitant to dismiss it.
Probably you are getting a ton of bots in Android Webview traffic, the quality of that traffic is usually very bad as it's used a lot by fraudsters apps what open a hidden webview trying to either autosubscribe the user to mobile carrier offers or to generate fake leads.

Ivan seems right.
All the conversions from Android Webview are SOI's and none of the SOI's became DOI's. Usually the camp has 40-60% SOI2DOI rate.
Yup, looks like bots for sure...
Please keep in mind that the JS bot trap will only catch the more "stupid" bots, the advanced ones will still get through. Usually, this simple bot test is enough to find the worst placements, for now at least ... but it might change anytime.
Thanks guys, that helps a lot.
