How to Create a new Google Account without Google+
If you want to make a new Google account, without getting yourself registered for Google+, you can still have this. At least for now, Google allows its users to create an account without being registered for other Google services like Google+. Officially we cannot say how long this option will last.
Use the old Google signup page
The old Google signup page is still available (shown in the screenshot below) for new users and it wont create a Google+ profile for the Google account automatically.
If you will go for the new signup page of Google, you will end up having a bundle of services including Google+. Further the registration procedure also requires you to enter several things like name, gender & mobile number as well.
Use the signup pages for Google Calendar or Blogger
As stated in the Google Operating System blog, online users are not yet forced to sign up for other services of Google i.e., Google Calendar and Blogger etc to create a new Gmail account or a Google+ profile.
This is it! If you need to create a new Google account without being registered for a Gmail account or a Google+ account you must use the old sign up page for this purpose.
