High-level analysis via Google Analytics and Website Optimizer

If you've improved the crawling and indexing of your site using Google Webmasters Tools or other services, you're probably curious about the traffic coming to your site. Web analytics programs like Google Analytics are a valuable source of insight for this.

You can use these to:

• Get insight into how users reach and behave on your site 
• Discover the most popular content on your site 
• Measure the impact of optimizations you make to your site
  - e.g. did changing those title and description meta tags improve traffic from search engines?

For advanced users, the information an analytics package provides, combined with data from your server log files, can provide even more comprehensive information about how visitors are interacting with your documents (such as additional keywords that searchers might use to find your site).

Lastly, Google offers another tool called Google Website Optimizer that allows you to run experiments to find what on-page changes will produce the best conversion rates with visitors. This, in combination with Google Analytics and Google Webmaster Tools, is a powerful way to begin improving your site.
