Among other interesting facts, the Technorati’s State of the Blogosphere 2009 report revealed that “search ads” (which would include Google AdSense in this context) were the 2nd most popular blog monetization method, while “affiliate marketing links” came 3rd [more here].
It isn’t unusual for an affiliate to run AdSense units simultaneously with affiliate banners, text links and other creatives. Here’s, for example, how one affiliate does it:
Are these two methods conflicting (one being detrimental to the best performance of the other), or can they be complimentary?
I’ve spoken with one super affiliate who has split-tested the performance of webpages with affiliate links only versus those that had both affiliate links and AdSense units. It turned out that the addition of AdSense boxes did not cause any decrease in his affiliate revenue, but on the contrary, increased that affiliate’s earnings by adding a new income-generating method.
It’s worth experimenting on your own, and complimenting AdSense ads with affiliate links, and/or vice versa. Chances are, you’ll discover that it’s really not an “either… or…” question, but a “both… and…” one.
Feel free to share your comments below. I’d love to hear other affiliates’ thoughts and experiences on this question.
