For readers who are searching for ways to evaluate their website's performance and boost its reach, Google Analytics provides a free service for which many other companies charge. Anyone with a Google account can access and use Google Analytics to track multiple sites, monitor social networks, and measure video. To sign up, select Sign Up from the homepage. Then enter a tracking code onto your pages. Hours later, Google Analytics will begin offering you data about your site, which can then be exported to Excel, CSV, PDF, and other files.
