During a search engine optimization (SEO) campaign, you will need to use Google Analytics to track the performance of your keywords in order to have a successful campaign. You will be able to know how much traffic each of the keyword brings to your website. Google Analytics will open up a world of information you probably never knew about visitors on your site.
With Google Analytics, other than collecting data about traffic from Google, you will also be able
to collect data traffic from MSN and Yahoo! search results with respect to your site and use it to
strengthen your stronghold on the search platform.
