I have add Google webmaster tool and Google analytic account to my website according to guidelines, my question is if i am verified by Google webmaster and through Google webmaster tool i am linking account to analytic, then is it necessary to add Google analytic code to each page of website?
you just need to enter the code in the main page (in header or footer) and not in all pages of your site
Adding code to only to main page (home page) may not fetch report of the entire website pages. Will it fetch?
if we talk about wordpress / blogger or any forum we just need adsense code in the main file (index.php) if you are using a custom script then you might need to add tracking code to every page which you need to track
This is what I was expecting. BTW, if you have a common footer for you website then you can put the GAC there. This will make sure that you have code in every page.
Google Analytics code must appear on every single page that you want to track. The way it works is, the javascript for Analytics will fires a request to Google's server to track the page that user visited. And for that to happen, the code must appear somewhere on that page. So placing Analytics code is required in order for a page to be tracked
