Google has become a part of our web life. Useful services not only for end-users but also for web masters. I discovered that they offer many free services I did not even heard about them. I am interested in founding all these services for use some of them in my web site. I think there are ready code lines to be included in any web site, about google maps, analytics, docs etc. I need your help to post here all the links that would show us what google offer for web masters. I think that when we write down all of them, it would be a very useful guide for everyone involved in web design and development.
