I want to track the total hits of each page in my website.
Is it possible using google analytics module?
If yes, what is Tracking ID in google analytics module?
Also how to use that module..
Please help me...

To use Google Analytics, you need to sign up for a (free) Google Analytics account at google.com/analytics. You get the tracking number from Google.

All that you need to do on your DotNetNuke site is go to the configuration page for the Google Analytics module and plug in the tracking number.

From that point on, you monitor traffic from the Google Analytics site. There is lots of good help an instruction there.

thanks craig...
I created an account in google analytics and given that ID in google analytics module in admin.
I have a doubt, do I need to apply this google analytics module in all pages? or this will track for all pages?

It will track all pages. If you take a look at a page's source, you'll see that the tracking code is added to the page.
