Now no more decorations for your google adsense blocks. We use to have beautiful images placed in our adsense blocks using a plugin Adsense Beautifier. The main advantage for having a well designed adsence block was to attract our visitors and making them to click these adsense links thereby increasing the chances of generating more revenue but now Google have made its clarification in this regard at their official blog post
We ask that publishers not line up images and ads in a way that suggests a relationship between the images and the ads. If your visitors believe that the images and the ads are directly associated, or that the advertiser is offering the exact item found in the neighboring image, they may click the ad expecting to find something that isn’t actually being offered. That’s not a good experience for users or advertisers.
Some greedy webmasters misused this feature and have fooled visitors, the advertisers, Google and earn bucks. This is a good step by Google but we have to sacrifice our designs and decorations.
