On admob, when I click on Monetize > AdMob Network report and then select "Targeting Type" in the drop-down selection (at the bottom left of the page), I see five lines:
- (Unmatched ad requests) - (unknown) - Contextual - Interest-based - Placement
Can someone explain me how such results are possible as I am in an Android App and no targeting information is provided to Google (for me, contextual is linked to the environnement of the user in the app like, the text on a webpage for a web-site visitor for example…)
Actually I would like to improve my ECPM by providing keywords and -if useful- user (non-personal) info to Admob as I do not do it yet.
Does anymone have any idea how this could be achieved and how Admob can currently propose keyword-based advertising when I do not provide anything to it? This is a mystery for me 🙂
Thanks in advance for the answers!
