Happy Halloween! For the special day, most of the search engines and portals have special logos or themes on their home pages.

In fact, Google’s logo was carved and filmed at Google and that made up what you see as the Google Logo for Halloween in 2011. Note, one of the pumpkins was 1,298 pounds!

Plus, Google’s dressed up the Google Webmaster Help forums and AdSense Forums.
