Two small improvements to Google AdWords

Google Adwords blog http://adwords.blogspot.com/ announced on Adwords ads in the top display made two improvements, this is two seemingly small but it has an important role in adjustment: One is to change the color of the ads at the top of the search results from blue to yellow, and the second improvement is that in the past, the shadow block of the ads will have an AD link, which is easy for users to accidentally click on the AD, resulting in a lot of invalid clicks, wasting advertisers' money. The improved link is only added to the AD link text, and the shaded block has no link, which greatly reduces the possibility of misclicking.
