Hi,
Nowadays by Google Analytics i can track only those visitors whom are visiting blog & article section of my site.I am sure that visits are coming to rest of the pages also…can anyone suggest me that how can i track rest of pages?
Welcome to SitePoint 
You need to ensure the analytics code is included on ALL of your pages. Google Analytics requires this code to be on each page to track each page.
Since this a SEO forum, I suggest you look for more information on Google’s own site at http://www.google.com/support/googleanalytics/bin/answer.py?hl=en&answer=55488 for more information - they even have their own forum.
