Google AdSense is one of the most popular services provided by Google because it helps webmasters earn money by simply placing Google's ads onto their site. Because it is so important for a lot of users, the company improved the service, adding new features to the way AdSense works.

It seems like Google wants to improve its developing process because its employees are aiming for another type of update: the one concerning the service's appearance.

If you're a registered user for the AdSense solution, you should know that when you're configuring your account, you can also personalize the appearance of the ads to fit them perfectly into your website's appearance. From the latest reports, it looks like Google renounced to impose this function, starting a test that will improve the ads' format.

The Search Engine Roundtable also identified the new appearance of the ads and posted a message on their blog to present an official response sent by Google to multiple users.

"Thanks for your email - as you've mentioned, the change that you saw was part of ongoing testing to improve our ad formats. Such variations are a normal part of our testing process and generally run for short periods of time only. No permanent changes are planned at this time. To maintain the integrity of ongoing testing, we do not permit publishers to opt out. However, please rest assured that such variations should impact only a very small percentage of your impressions. We appreciate your patience and understanding as we work to improve our program," the e-mail said.

I must say that I'm really amazed by the fact that Google started this test without an approval from its users so, if you hate the new appearance of the AdSense ads, you cannot change them using a function provided by the company.
