Hi Mopek1,
Wow that is a really open ended question. I work the Mainstream side now and came from Adult. There are differences for sure... but there are many similarities. One thing you will need to get used to is the payout structure. It is VERY different.
The company I work for (LeadFlash.com), offers many different offers, ranging from Auto Loans to Education, but we focus on Sub-Prime Credit offers such as Payday Loans. Now conversions with Payday Loans for us RoX...That I can vouch for 100%.
As far as what they are seeking?
I would not say surfers go looking for mainstream ads (that would be odd), rather the sites that they visit SHOULD complement the sites content or audience. As far as conversions go with mainstream, it all depends upon the traffic (like adult). Overall, I feel that mainstream converts extremely well, just have to find the right product or niche.
If you have any questions, feel free to contact me or just sign up direct if you decide to go the mainstream route. Make sure you you mention
"GFY" in the notes, so you are accepted.
