SiteAnalyze collects data on the system configuration of each device that users access your site with.

This data includes:

• Screen resolution
• Operating system
• Browser make and version.

This information can be useful to track trends in usage of specific browsers and operating systems, and to review the screen size that is typically used to view your website.

Although best practice dictates that website design should aim to be accessible to all users using any system setup, you can gather information that enables you to prioritize and make design decisions based on actual usage.

For example, you may find that users accessing your site using mobile devices account for a far smaller number of page views than user numbers would lead you to expect. The reason may be that users with such devices abandon your site very quickly because the site does not display properly on smaller screens. Filtering data by screen size enables you to decide whether this lost traffic represents a large enough proportion of your total website traffic to warrant the development of a CSS style sheet specifically for mobile devices.
