If you have a link within your advert text that you would like to track, there’s a fairly simple way to do this.
You can use a URL shortener like Bit.ly
Enter the link you would like to track in the URL bar and click the shorten or create button.
You can use this as the application URL in your advert.
You can see how many times this has been clicked by adding a plus sign to the end of the shortlink i.e https://bitly.com/2jTV7Yl+
This will display a page with details on the usage of your link.
