i have seen some websites having their Google search bar with out Google Logo. Is't that against TOS? or it is allowed to make adjustments. Even if adjustments are allowed, is it legal to remove Google Logo?
The Search bar can now be customized to a certain extent from within your Adsense account. Instead of having a Google logo, you have the option of having a "Google Search" button instead.
Before you couldn't do that, but now you can as Crusader mentioned. If you go into your adsense account you should notice that they have added more options. Skinny
i just visited a site funmaza.com where they have not used logo and not a Google search button rather a simple search button also i have seen it on some other sites as well
The other option would be that they are premium publishers, or that they aren't using Google Adsense for search, but rather just the normal search function.
