Naming conventions that save reports
- • Always lowercase, GA4 is case-sensitive and will split your data otherwise
- • Use underscores instead of spaces (spring_sale, not Spring Sale)
- • Keep a shared spreadsheet of source/medium pairs so the whole team tags consistently
- • Never tag internal links, UTM parameters reset the session and corrupt attribution
What UTM parameters do
UTM parameters are tags you add to a link so analytics knows where a click came from. They feed the source, medium, and campaign dimensions in GA4. Inconsistent tagging (Facebook vs facebook vs FB) splits one campaign across three rows, which is the most common reason campaign reporting turns into a mess.
Stay consistent or lose attribution
Pick one casing and one vocabulary, then never deviate. "facebook / cpc" and "Facebook / CPC" are two different sources to GA4. The cost of inconsistency is invisible until your campaign report is unusable.
How to use it
- Enter the destination URL
- Fill in source, medium, and campaign, plus term and content if you need them
- Copy the tagged URL
- Keep your naming consistent across every campaign
Tagging tips
- Use lowercase everywhere to avoid split rows
- Keep a fixed vocabulary for source and medium
- Do not tag internal links, it overwrites the original source
