When I talk with many AMs, I'm confused, because I do not know who to introduce my traffic type and traffic source.
My traffic source is buying traffic from nativeads,traffic type is display and banner. Who can help me to organzie these words?
Thanks very much!
Just “Native” will do the job buddy.
If you´re not sure just explain them what you do.
AMs are no monsters but mostly nice people.
Don´t be afraid.
No worries, sunwukong, nothing wrong with the explanation you gave already. Like Twinaxe is saying, try to explain it - we are not monsters 
Cheers
yep, once I got in touch with my adcombo AM, the only thing I had to tell was my type of traffic, which GEOs and niches I was most interested in. Not many AMs ask you to actually disclose the name of the source, otherwise they wouldn't have many folks dealing with them
.
Another thing is - I wouldn't lie, 'cause then you don't have the manager's trust and don't have the best recommendations for your source, which hurts you both.
AMs mostly wanna make sure you know what AM is about and that you're not just going to waste their time. So you don't wanna sound like you have no idea what you are talking about, but there is no need to disclose to many details either and every AM knows this is a sensitive area.
So what you actually wrote in the opening post is fine : native, display, banners ... that pretty much explains it perfectly 
I am the Nice AM you can talk to
, and sunwukong孙悟空 is a cool name. Add me on skype: live:1223291890 or qq/ wechat 472235830 (if by any chance that you have one)
Even your first explanation would be pretty clear for an experience AM. Actually, the more you share with a trustful AM, the more accurate offer/advice he would be able to provide. So don't be afraid and be honest and clear!
