UTM parameters, without the mess
UTM parameters are labels added to destination URLs so analytics tools can group visits by source, channel, campaign, and placement. The hard part is consistency, not link assembly.
The five common fields

Rules that keep reports usable
- Choose lowercase values and one separator.
- Keep source and medium names stable across campaigns.
- Use campaign for the shared initiative, not the individual link.
- Use content to distinguish placements and creatives.
- Never place email addresses or other personal data in a URL.
- Validate the final link before publishing it.
