This question already has an answer here:
The google tag wiki should be edited too:
Tag is intend to mark questions related to the products of Google your using on your computer.
- Google website and search engine
- Wikipedia article on Google Inc.
Since there's already a google-search tag. I think the google tag should be like the mozilla tag - it should relate either to the company itself or to its products in general. Google.com questions should be tagged only with google-search. So there's no way there are 424 question about Google Inc. / Google products in general. Most of them are about the Google search engine or about Google Chrome.
Some questions are tagged with googlesearch instead of google-search, too.
