AdSense Allows Other Contextual Ad Services on the Same Page
January 20th, 2007 by Scott W
JenSense confirmed it, and I read it on ProBlogger. You can now run other contextual ad services on the same page as your Google AdSense ads, so long as they don’t resemble the AdSense ads and both services allow it:
I followed up with Google on the situation, to find out of the removal of the clause would mean that competitor’s ads would be allowed on the same page as AdSense, provided they didn’t resemble or mimic AdSense ads, and that the AdSense terms would eventually be updated to reflect this policy change. And the answer is yes!
Unfortunately, the YPN network is still not allowing other services to run ads on the same page:
Update: I spoke with Yahoo Publisher Network on this issue, and they say that as of today, page level exclusivity still exists. This means you still cannot run YPN on the same page as another contextual ad network. However, they will listen to publisher feedback on this issue and take it into consideration for future YPN terms updates.
Now personally, I don’t think you should ever have too many ads on a given web page. Three or four ads are plenty and, depending on how you’ve blended them into your design, still have the ability to look tasteful. It’s when you throw in even more ads and different networks that it becomes more annoying to look at.
What I do recommend is testing a few services at once to see which end up bringing back good revenues. For me, I will always stick with AdSense as it is not only easy to use but it has also paid me well.
