Free UTM link builder
A UTM link builder adds campaign parameters to a destination URL. Use consistent names to compare visitors, customers and revenue by campaign. Your inputs stay in your browser.
Keep tags predictable
Use lowercase source names, use the same medium for the same channel, and keep campaign names stable. Tag incoming campaign links; tagging internal navigation can overwrite the source that actually acquired a visitor. Do not include names, emails or secrets.
