Try the Share Guild option: http://knights-and-dragons.wikia.com/wiki/Share:Guild

It works for us and I advertise for three guilds on android.

The other way also is if your guild goes on a run and pushes t25 or t10.

Other option also if you have someone in your guild willing to put the time, effort and gems. That person can go on an individual run in the arena or epic boss and advertise your guild in their name.
