Last year we advertised on a website and I would like to track the sales from that site. I can see the Referrers by Session in Analytics… but I can’t see how much/many resulted in actual sales.
Add campaign URL parameters to the link on the website you want to track from and you’ll be able to see revenue generated in Google Analytics: https://support.google.com/analytics/answer/1033863?hl=en#zippy=%2Cin-this-article
You can use this link to build a URL: https://ga-dev-tools.web.app/campaign-url-builder/
