Introduction: Understanding Google Analytics
Google Analytics is a powerful tool for measuring various aspects of your website's performance including how people found your site, how they explored it and how you can enhance your site visitor’s experience.

All Right, but How Accurate is Google Analytics?
To answer the question of how accurate Google Analytics is depends on how one defines accuracy. Is it accuracy in terms of measuring page views? Accuracy in terms of measuring site activities? Accuracy in terms of whether a user actually visits the site and performs some type of activities?
Unfortunately, there is no fool-proof answer. Keep in mind that Google Analytics' accuracy depends on how fast a site loads and whether the Analytics code was implemented properly.
If you have correctly embedded the Google Analytics Tracking Code and your site is well designed to load as quickly as possible, then Google Analytics will accurately measure your site data and performance.
