when you buy ad from other websites ( pay someone to advertise your business), do you perfer pay per impression or pay per click ??

try unique click through or something if you can both methods are susceptible to fraud.

Ya or best of all, just have an affiliate link from the banner so if you get something out of it then you get something out of it.

PPC without question. At least then I have a semi good idea they've seen the value proposition, not just a banner where I cant describe it all.

I used ppc to a company that pays other people to click

What are the best affordable PPC programs? Does anyone know of any that accept PayPal?

I've never tried them, Always thought that they would make you pay more by having people clicking on your link

PPC is best, but can be very expensive. The trick is to ensure that the advertising is highly targetted. Purchasing clicks on google can be very expensive. Many people recommend finding small sites offering competitive PPC. It can be hard work finding targetted sites though.

I like PPC better

pay per unique click :)

I usually choose PPC because its easier to work out how many visitors your going to get from your campaign

What a lot of people have been starting to do is pay for qualified clicks. People click on a link, banner or button and come to a landing page where it asks them to fill in more information to proceed. The information is sent to you and you pay for that qualified lead.

Makes more sense then just paying for someone to click on your advertising. Remember your the customer :)
