A senior member at WebmasterWorld forums says that he received a message from Google within the Adsense message center informing him that if he makes a change to his site, it will result in more money.
In fact, Google said they ran simulated experiments on making the change and it led to increased earnings. Now all the publisher needs to do is implement it and see the money come in.
The Google message said:
Recommendation to opt in to image ads in a text-only ad unit. We've run a simulated experiment on your site's ad traffic. It shows that some of your ad units, which are currently enabled for text ads only, could earn more if they were also enabled for image ads.
I've never seen Google say they have run a "simulated experiment" on a site but I guess it is easy enough for them to do and then dish out automated recommendations for the publisher.
Nice to see Google AdSense making these predictions not just based off of generalities but now based off of specific case examples on your web site and your audience - at least, that is what this applies.
