I’ve subscribed to WhatRunsWhere since 2015. It has always been the go to tool for checking competitors on websites we aren’t allowed to track. It’s extremely useful for a variety of use cases, from checking on competitors, to finding websites that are hard to track, to finding what media a competitor is running. The data it presents is extremely useful, and my clients have been very happy with the data it’s been able to find for them. I have used it to check my competitors in various countries, and WhatRunsWhere has been extremely useful. It’s a simple tool that does what it does well, and for a good price. I would use it for more than checking my competitors, but a few years ago WhatRunsWhere stopped offering mobile data. I’ve emailed, but no answer. In the end, my clients have stopped using it.
