Referral Ads Vs Ads

Difference between refferal ads and normal adsense pay perclick ads?

I was long been confused with what is the difference between Adsense refferal ads and normal adsense ads The Difference between referral ads and “normal” AdSense is that you won’t get paid per click, but only if the visitor who clicked the ad buys something from that site, too (or performs another action, like a newsletter subscription). For every ad, you can check the detail view to see what action needs to be performed and what revenue it will bring to you. Referral ads mostly look like normal ads, but they read “Referral Ads by Google.” And there’s one other layout option which normal AdSense don’t have: the link-only ad type, because this link will automatically adjust to your page’s font settings, and not break the text flow (and it will also not carry any Google-branding, or disclosure).

Other difference between the AdSense referral program and the normal advertising program. One of them is that you can actively promote and encourage readers to click your referral links. In the referral type of ads you won’t get paid per click but only when the reader meets the specific required action. If you do recommend the product or services you’ll increase your chances of conversion as you are helping in selling the product or services.
