I've posted about this many times before. AMs to me are very important. I will easily fire one if I don't find them responsive, knowledgeable, and persistent. The best ones to me are the ones the work really hard for you. Be knowledgeable about the traffic sources, give tips and advice, talk to them daily about their needs. You wanna earn their trust and loyalty, because usually they have 12 other AMs breathing down their neck. I personally liked to be hit up daily, some do not, figure them out.
Here's a big tip, one some networks may frown upon. Make some of your own LPs for some of you networks top offers, and give them out to your pubs who wanna test out the offer, basically give them the whole package, without risking losing your loyalty to your pubs ofcourse. That and knowing your traffic for certain verticals will help out a lot, but remember don't snake your other pubs sources, be more general and give at half-informations.
I won't say names, but most networks only allow their AMs to talk offers and payouts, , bug your pubs, and only allow them to give out vanilla advice. That to me, doesn't help out anything. But also remember if he knew how to profit on all the campaigns, he wouldn't be an AM he'd be an affiliate, so pubs, don't always expect the world from you AMs.
I'm too hungry to type anymore, you need any more info, just ask. -v3ne
