Know which campaigns work
Add utm_source, utm_medium and utm_campaign (plus optional term, content and ID) to any URL, and Google Analytics 4 and other tools will attribute visits to the right campaign. Presets fill in the standard values for Google Ads, Facebook and Instagram ads, organic social, LinkedIn, X, email newsletters, affiliates and print QR codes.
Values are lowercased and hyphenated automatically (GA4 is case-sensitive, so “Facebook” and “facebook” would be split), and the tool shows which GA4 default channel the visit will land in — warning you when a medium won't be recognized and would end up as “Unassigned”.
