Are Google Search Results Pages Changing Again?
Google has recently taken steps to ensure that search results are more accurate by using the new Panda search algorithm, and now they have enhanced the design, layout and look of their search results pages.
Results pages are a bit more clean looking, with additional white space, sharper colors and differences in the way results themselves appear. The new design was likely incorporated to make the pages a bit more tidy and professional, and hence, more accurate, at least in appearance.
Another likely reason for the new design is to enhance the way that certain advertisements appear within search results. Google isn't trying to trick you, but rather entice you by letting you see things just a bit differently.
