This is probably a noob question but I haven't done a whole lot with mobile yet and I'm looking for a way to filter out the traffic and show a different offer depending on what type of device the person is on. For example, if they are on a desktop/laptop, I want them to just see my regular website with the normal CPA offer I run. However if they come from a cellphone/tablet, I would like to be able to show a completely different offer. Is this something I would need to hire a coder for, or is it pretty simple to setup? Thanks.
