How can you do demographic targeting with mobile? For example, if my niche is gambling, how can I target males who are 18+? Or sports related mobile sites?
It depends on the network, but in general you can't target precise demographics: because you're advertising on a wide range of sites, they don't have precise demographic info on their users like Facebook or POF do.
You can target the category of the site, though - so, for example, I believe Decisive actually has a "sports" category that you can target your ads to. And you can drill down to target individual sites, too, giving you pretty precise control over where your ads are appearing.
Thanks caurmen, thats just what I was after.
So far doing demographic targeting on mobile I would say is accurate only on FB mobile.
Some other platforms do offer it but I don't see it being accurate.
Category targeting is what comes closer to it on most mobile platforms.
