Google has just officially launched Google Analytics.

Google Analytics is a free service that Google offers to its customers to allow them to track, monitor and measure with great accuracy statistics relating to traffic, conversions and page views on your web site.

Google Analytics tells you everything you want to know about how your visitors found you and how they interact with your site.

You can find out how profitable your keywords are across different search engines and multiple online campaigns. You can identify where your best online customers come from and which target audiences are the most profitable for your specific content.

To make Google Analytics work you only need to place the special snippet of code that Google provides you in side the page templates of your web site.

No need to download anything.

If you don’t edit your own site, your webmaster, designer, or hosting provider can probably do it for you in under five minutes.

Google Analytics has been particularly conceived and designed to help advertisers track and optimize their campaigns across multiple sites and even across multiple keyword advertisers.
