Key takeaway
UTM tags label URLs for analytics. Consistent naming beats clever naming.
Messy UTMs permanently fracture reports.
What it means
utm_source, utm_medium, utm_campaign (+ term/content).
Tags travel in the query string.
Case differences split reporting.
When you would use it
Paid and meaningful owned clicks.
Avoid stuffing every internal nav link without reason.
How to use the tool
Use the matching TCB Tools page and work top to bottom:
- Open the UTM Builder.
- Enter base URL.
- Fill lowercase source/medium/campaign.
- Add optional term/content.
- Copy and test incognito.
No account is required. Results update as you type.
Parameter method + worked example
Example: https://example.com/landing?utm_source=google&utm_medium=cpc&utm_campaign=spring_sale
Lowercase, consistent separators, no spaces.
Keep a team glossary.
How to read the result
Fragmented reports usually mean naming drift.
UTMs label traffic; they do not fix landing pages.
You own governance.
Common mistakes
- Mixed case/spaces. Lowercase.
- Renaming campaigns weekly. Stable IDs.
- Wild internal tagging. Be intentional.
- Wrong host/canonical. Use final URLs.
- No QA click. Test once.
