We use Matomo web tracking on our clients websites - we are interested in referrer/campaign tracking at an individual level for attribution purposes (via userid or by ecommerce order id for known individuals or matomo visitor id for anonymous browsers). We have recently been asked by clients and prospective clients about the upcoming changes made by google. We have responded that we are only tracking 1st party data which has been consented - however the recent update by google has suggested that it won’t support any user-level tracking - can anyone provide any information on this? A matomo visitor id is a user level identifier, will this continue to be supported after Google’s changes? It would be helpful if Matomo issued an official response (like many other companies are doing) so that we can reassure our clients or be prepared to make changes.
Here is the official statement from google and an article that attempts to explain the changes. I look forward to receiving some advice on this matter.
