The Logo is an obvious parody fo Google's original logo. However the ZapLook logo is in all capital letters, and the colors are different, for example it starts with a red Z, where as Google starts with a blue G.
You can vist Zaplook here.
Zaplook search was used in other Dan Schneider shows, such as Drake and Josh. It was used in the movie and when Drake's hands mysteriously turned green, he used Zaplook to search for info and cures. It was used probably more than just that on Drake and Josh, too. Zoey 101 and Victorious had also used this fictional Google parody.
The actual URL redirects to iCarly.com. It is a compound word using both "zap" and "look", referring to the fact that you can look stuff up quickly, or as fast as a "zap".
As seen in the photo, the logo colors are red, blue, green, purple, and yellow, and the rest are repeated. Although it is a parody of Google, the logo doesn't change to show special occasions (at least not onscreen).
It does not have some of the icons that Google does, such as images, maps, videos and earth.
