My guess would be that it’s the number of times your listing on IDEA FitnessConnect was seen by someone searching for “Fitness Instructor” or “Personal Trainer” in your city or zip code. This is different from your “Profile Views” which, from my understanding, means the number of times people have actually clicked on you to view your FitnessConnect profile.
Let’s take a Google search as an example. When you type something into the search box and click “Google Search” you’re given a ton of results. The ones that you see the links to (but don’t click on) have merely made an “impression” on you. On the other hand, the links that you do click on would be considered the pages you’ve actually viewed.
Does that make sense?
