Since then, the thread has grown to a point where AdSenseAdvisor has come up with a nice list of features and fixes they would like to implement. Here is the list AdSenseAdvisor has complied:
Finding ads - Improve the search feature, including letting me search by types of ads - Make it easier for me to identify new referral products
Ad categories - Categorize advertiser ads more accurately - Consider having sub-categories and then allowing me to default up a level when ads run out in the sub-category
When an ad runs out... - Find a way to tell me if the ad I chose is running out or already ran out of budget - Make sure that I'm not being shown unselected ads when I unchecked 'Pick best performing ads' - Give me an option to substitute in something else
Quality of the advertisements - Get advertisers to create attractive landing pages - Make sure Google Product referrals are showing properly - Remove the blue border under the Google Product referrals - Let me exclude specific referrals when selecting 'Pick best performing ads'
Other - Be more clear that Network Performance indicates how well an ad has performed for publishers across AdSense - Give me a way to change ad units without generating and re-pasting the code
