This is easy. We tag each category of advertisement with specific codes, called UTM codes, that Google Analytics can handle. For instance, if you are promoting two brands, or two models, we will assign different codes to each so you can see which category is driving traffic to your site. But, it's important to note, by far the majority of traffic generated through digital advertising today is when somebody sees an ad and then visits the site directly, rather than actually clicking on the ad. It's about a 10-to-1 ratio of people who visit sites directly rather than click on an ad. We can track people who are exposed to ads and then visit the site directly for 90 days from when they see the ads. In other words, Google Analytics is helpful, but will significantly under-count the traffic generated by the ads.
