Someone told me if you use Google Analytics and Adwords, you rankings will be higher. Do you agree?
No. using Google Analytics, GMail, Google Adwords, Google anything will not help you with SEO/natural rankings. It will obviously help you with Adwords if you use their tools to tell you about keyword opportunities and such.
For the many conveniences that the search enigne provides, there is a price. Nothing is free. They get to datamine your behavior and your website visitors behavior. Some of my internet marketing friends call these tools spyware.
