Google appears to have rolled out (to what extent we're not sure) a design change to its search results pages. The change seems to be very minor and insignificant, but Google altering SERPs is just something that can't be ignored by the search industry.

The (hardly) noticeable changes are a little bit of padding on the left-hand side, and a slightly smaller version of the Google logo. It's just enough to make you wonder if it's changed or if you're just crazy.

It is unclear if the changes are widespread or just experimental. Phillipp Lenssen at Google Blogoscoped points out, "I'm currently seeing a slightly changed layout for Google results. The Google logo has gotten smaller, and there’s more padding to the left. In Firefox, the file holding the logo for the new layout is called nav_logo6.png (when I open the old layout in Chrome, it’s nav_logo4.png)."
