We keep track of all the visitors who view your images and your products. At any time, you can login to your control panel and view comprehensive data regarding your visitors.
How many hits have your images received? Where did the visitors come from (i.e. city, state, and country)? All of this information is available.
In addition, if you use Google Analytics, you can link your your Pixels.com account to your Google Analytics account and track your visitors from there, as well.
