Test page for Matomo
I will add two lots of query strings to this URL:
https://www.eastsussex.gov.uk/privacy/test-page?utm_source=website&utm_medium=page&utm_campaign=test&utm_content=utm
https://www.eastsussex.gov.uk/privacy/test-page?mtm_campaign=test&mtm_source=website&mtm_medium=page&mtm_content=mtm
I will open each of those URLs in 2 different browsers and hit refresh over and over again. Matomo should record just 2 sessions - one from the utm tracking and one from the mtm tracking.
This page added to site map exclusion list.
