If you are using just a basic click tracker, it’s easy to test. Just visit the click tracker link and see if you end up at the destination URL.
If you are using advanced features like click limits, country limiting, device limiting, return visitor settings etc., it may be more difficult to test.
If the click tracker settings should reject a click from you because of country, device etc., you should end up at the rejection URL. You personally will not be able to test the destination URL. In cases like this, have someone that would pass the rejection tests, test the click tracker to see if they end up at the correct destination URL.
Another way to test a click tracker is to post the click tracker link on a social media site and ask your friends to help by clicking it. Then, check the stats for that click tracker to see if they look like you expected.
