Reports via DigitalPoint Forums & WebmasterWorld that Google has sent out a batch of email surveys to AdSense publishers. One member said;
Took about 10 minutes to complete. First, it asked general questions about how I liked adsense, how I used it and what would I like to see. Then it gave some examples or maybe even _hints_ of features to come and asked my thoughts about them. Hopefully I get picked for the $1000 gift card!
So they provided an incentive of $1,000 to have people fill out the 10 minute survey.
Some members were cautious about the validity of the survey. I personally did not see the survey.
If you like to receive these surveys and you are an AdSense publisher, or if you like to not receive these surveys, you can tell Google within your email preferences section.
