I havent tried myself, but I am relatively certain that it depends on the vendor you are promoting for. You should read the guidelines for each vendor as they will usually outline what kind of marketing is accepted.
No, pepperjam has ads that look very similar to adsense ads. I personally have had no problem using the banners and link from pjam, but I dont use the similar looking ads on the same page as adsense. Just playin it safe...
Why on earth would you use these pepperjam units? Instead of Adsense, which can recognize the content of the page, and has tens of thousands of advertisers bidding to be on the page, you’re going to go with a solution that is limited to a few programs that pepperjam has and doesn’t have Google’s targeting? What’s the pitch…. “almost as easy as AdSense… but 1/10th the profits!â€
As long as the ads don't look the same as Adsense ads then I guess it should be fine. I have used Adsense and pepperjam on the same page, but the pepperjam ads didn't look anything like Adsense ads.
I think the part of their affiliate program that AdSense publishers will be most interested in is their lookalike AdSense ad units. They are called pepperjamADS, which are styled very closely to Google AdSense in format, but allows you to use multiple affiliate ads in a single ad unit, the same way multiple advertisers appear in an AdSense ad unit. Once you are approved for some affiliate programs, you can then go and generate pepperjamADS for your site (they won’t show up in the pepperjamADS tab until they are approved, unless you have added one of the many programs with automatic approval). Do note that Google doesn’t allow you to run ads on the same site that mimic AdSense ad units, so the easiest way around this is to use a border if you have blended ad units. If your AdSense already has a border, use pepperjamADS as blended with the border and background of the ad unit matching the background on the page. Otherwise, change the color scheme dramatically.
Pepperjam Network offers the usual affiliate ads and product feeds that you would expect from any affiliate network, with a diverse number of programs. I did a quick runthrough of their entire affiliate program list, all the programs they offer fall well within the AdSense terms, so you should be able to select any of their ads without running afoul with Google content policies.
