Is anyone using multiple ad sites on their blog? Have you determined if it is worth adding a second company along side of AdSense? If so, which one?
I use WidgetBucks as well. They are paying great and I love their widgets (ads) Check them out!! Link in my signature
I thought using other programs similar to AdSense alongside AdSense (both on the same site) is against the TOS...?
Nobody has been paid from WidegetBucks as of yet so how can you say they're paying great? You're just promoting your referral link. Anybody reading this post, please do some research and read what virtually every serious blogger has to say about WidgetBucks. They're slow, they don't convert and they have no history of payment yet. I'm not saying that WidgetBucks might not get better over time but for now, I humbly suggest sticking with proven affiliate programs like Commission Junction/eBay affiliate and Kontera (like Randy mentioned).
only if they can be confused with Adsense ads. as long as they have a different look & feel, it's ok.
Competitive Ads and Services In order to prevent user confusion, we do not permit Google ads or search boxes to be published on websites that also contain other ads or services formatted to use the same layout and colors as the Google ads or search boxes on that site. Although you may sell ads directly on your site, it is your responsibility to ensure these ads cannot be confused with Google ads.
yeah, just like i said: only if they can be confused with Adsense ads. as long as they have a different look & feel, it's ok.
