1. Can you have more than one offer on a web page? From two different networks?
A: In MOST cases networks give you freedom on how you promote their offers, even if it meets combining with other networks. Just don't promote adult offers on the same page with their offers.
2. What is the difference between "EPC" and "Rate"?
EPC means "earnings per click" or maybe "e" stands for effective; I can't remember. Either way, it basically means how much you earn per click. If you make a $20 sale after 10 clicks, your ratio is 1:10 conversions, and your EPC would be $2 per click, which is a $2 EPC. Rate could mean a variety of things, but usually it refers to how much you are paid comparative to the total cost OR the conversion rate, which I just explained.
3. "Incentive" vs. "Non-Incentive"?
Incentive offers mean that you can convince or persuade the lead (the person completing the offer) to do the offer. An example is GPT (get paid to) sites, where the site will promise the visitor a dollar or so to complete the survey. Obviously when someone is paid to complete an offer, the advertiser (owner of the offer) will have a much lower conversion rate than if the visitor had clicked it on his/her own interest. The person will most likely complete the offer quickly and not give a shit about the product itself.
An non-incentive offer is basically the industry standard, which means that the leads MUST be complete the offers on their own account, and not because of any influence or persuasion. For example, banners on a site. If an advertisement looks good to a visitor, he will pursue it on his own accord and potentially even buy the product, not because he is being paid to do so. Non-incentive offers are the norm, so if you see no indication of either, assume it is a non-incentive offer.
4. "Scrubbing"?
Scrubbing is a term that is often thrown around with "shaving". Scrubbing is a legit action by the advertiser (owner of the offer) where they deem a lead is not acceptable (maybe the visitor filled in random stuff or had already done it), so they discredit the lead. Email submit offers are often scrubbed hard, and many people call it shaving instead.
Shaving is when the advertiser does not credit your lead for no justifiable reason except to avoid paying you for it. Shaving is quite rare on trial offers (offers where they have to actually purchase something with a credit card) compared to free offers (like free dating offers).
5. Adsense on same site?
A: Adsense is perfectly acceptable to networks, as from what I know there are never adult adsense ads (could be wrong). Either way, people seem to believe that adsense is an automatic way of generating money, even if it is little. True, you may get a few cents a click, but then you are losing traffic to where they SHOULD be going, which is the much more profitable CPA offers. Obviously there are exceptions to this, like if you have a very high EPC on adsense, but you are asking about CPA so I doubt you want to learns the specifics of adsense.
In summary about adsense, yes it is allowed with CPA offers, but you will VERY likely lose traffic to $0.10 adsense clicks instead of potentially much higher EPC CPA offers.
So yeah, I typed a lot but I'm in class right now and really bored.
***IMPORTANT*** I really hope you read this part. If you intend to do black hat CPA make sure you realize what you are doing is wrong, and almost certainly theft. People on BHW seem to have double standards and criticize other people's methods because of "morals". This is ironic because those people then proceed to send fake leads or seduce 40 year old men. Do not end up like those hypocrites please. Realize that if you sending fake leads you are stealing and someone is losing in the end, no matter how much you try to justify it. I realize that the stuff I do personally is bad and probably make me a bad person, but at least I acknowledge it. WE ARE ALL THIEVES ON BHW to some degree.
