Google Analytics (GA) is a free service that generates detailed statistics about the traffic and visitors to a website or blog. In addition to the usual traffic metrics (pageviews, visits, unique visitors, bounce rate, time on site etc.), GA also provides comprehensive statistics on website/blog audience, traffic sources, content, keywords and more.
I) Creating an account with Google Analytics
1-Go to Google Analytics, click the Google Analytic Now link on top right corner of the page and sign in to your Google Account.
2-On the next page click the Sign up button.
3-Next supply all the necessary details -account name, blog URL you wish to track, time zone, data sharing preferences, and your country or territory.
4-Read the terms of service and tick the “Yes, I agree to the above terms and conditions” checkbox.
5-Click Create Account button and you’ll be taken to Tracking Code Configuration tab.
6-The next step is to find the Web Property ID (a.k.a UA number) -a unique ID given to the account you just created. Disregard all other items in this tab, the only thing you need is the UA number.
7-Copy the UA number as you’ll need to paste it later on.
II) Installing Google Analytics on your blog
This is a two-step process. First you need to register the Web Property ID with Blogger, and then import the tracking code into your template.
Adding Google Analytics ID to your blog
If you are using the new Blogger interface, click the dropdown menu next to the name of the blog you wish to track and navigate to Settings > Other > Google Analytics. (For old interface, go to Settings > Basic > Google Analytics Web Property ID).
