at the present time, advertising on my site is managed by a company that sells ads to relevant companies then serves them on my site, filling the remaining inventory with other ad networks.
At this time, they do the selling and the serving. I receive a monthly check which is the ad sales minus their commission (50%), minus serving costs.
There is no reporting, I never get any other detail other than the final amount.
Because of this - I would like to start moving to my own adserver (bonus if I don't need to physically host it myself) and just plug the ads that they sell.
How complicated is it? Worth the effort in your opinion, counting that I don't want to do any selling myself ?
Also, a big chunk of revenue is lost because they don't do responsive ads. All ads are sold on a desktop pageview basis and I know nowadays you can place some kind of placeholder and it will be rendered with a properly sized ad depending on the resolution.
Am i getting into a lot of trouble for wanting to do this on my own?
