If you can't measure it, did it have an impact? Without website performance metrics, the only thing you can say for sure is that you don't know how your campaigns are working. Many businesses don't make it because they fail to learn from mistakes and course-correct. Google Analytics can give you the insights you need to make those changes. When Marketing Land compiled estimates for Google Analytics' 10th anniversary last fall, they put the number of websites using the service between 30 and 50 million.
Once you set up a Google Analytics account, you can monitor multiple websites. Each will have its own dashboard, featuring six broad categories and sub-menus. The service also provides you some examples of how to use the tools within each section to drive positive results for your business. Here are some of the metrics and how they can work for you.
