At first, I was confused why there is a "blank ads" and now I realized the "live ads" will be automatically appear on the page after officially approved by Google Team and notified by email.
This makes Google Adsense become more interesting and attractive.
The statement below shows the New publisher application process
Wednesday, August 31, 2011
We’re continually evaluating our AdSense application process in order to ensure the safest possible network for our advertisers, as well as the best possible experience for you, our publishers. With that in mind, we’ve now implemented a change to our initial review process that will result in a stronger AdSense network. Improving the quality of the network will drive more interest and demand from advertisers, increasing the earning potential for all of our publishers.
Starting today, we’ll begin adding a new step to the review process and sending notifications at two key points. After a new application is submitted, we’ll begin with preliminary checks on the site and the applicant’s submitted details. If the application passes through this first stage, we’ll notify the applicant by email, grant them account access, and provide them with ad code to place on their submitted site. It’s essential at this stage for the applicant to place the ad code on their site, as the review process can’t be completed until the ad code is implemented.
However, live ads won’t immediately appear once the ad code has been placed on the submitted site. Since the application hasn’t been fully approved yet, temporary “blank ads” will be shown instead. These blank ads will blend in with the background of the page, so users won’t see them and the user experience won’t be impacted. As a result, there’s nothing to click on and thus revenue can’t yet be generated. If the applicant logs into their AdSense account at this stage of the review process, they’ll see a reminder that their account is still under review.
Soon after the ad code has been added to the submitted site, a final approval decision will be made and the applicant will be notified by email. Newly approved publishers will see live ads automatically appear in the existing ad units on their pages. These publishers are then welcome (and encouraged!) to add more ad units to their submitted site and to any other policy-compliant sites they own. We also encourage new publishers to ensure their sites are available to be crawled by the AdSense robot(Mediapartners-Google), and also to use our best-performing ad formats.
If you’d like more information about this new approval process, please visit our Help Center or feel free to post questions about this topic in our Help Forum.
Thanks for being a valuable member of AdSense as we continue to improve the quality of our network.
