What is UTM Naming Convention Checker?
Messy UTMs (spaces, CamelCase, underscores) fracture Analytics reports. ToolYour UTM Naming Convention Checker validates utm_* values or a full URL against lowercase-hyphen rules and suggests slugified fixes. It does not rewrite production links for you. Same route via REST and MCP (POST /api/v1/marketing-apis/utm-naming-convention-checker).
What are common questions about UTM Naming Convention Checker?
What fails the check?
Uppercase, spaces, underscores, or other characters outside a-z0-9 hyphen segments.
Can I pass a URL instead of fields?
Yes — provide url and present UTM values are extracted then checked.
Does it check values against a custom naming doc?
No — it checks against the lowercase-hyphen convention only. For a custom taxonomy (e.g. required campaign prefixes), review suggested slugs against your own doc manually.
What are the key features of UTM Naming Convention Checker?
Per-key issues + suggestions
Each value gets ok/issues and a suggested lowercase-hyphen slug.
How do you use UTM Naming Convention Checker?
Paste URL or UTM values
From live ads or a naming spreadsheet.
Apply suggested slugs
Rebuild links with UTM Builder using clean values.
Why this tool exists
UTM values with mixed casing, spaces, or underscores fracture Analytics reports into duplicate rows for what should be one campaign — 'Spring_Sale' and 'spring-sale' show up as two different campaigns. UTM Naming Convention Checker exists to catch that before it splits your reporting.
Problems it solves
Naming drift happens gradually as different team members tag campaigns their own way over months, and by the time someone notices in a quarterly report, dozens of links already need retroactive fixing (or permanent reporting gaps). A pre-publish check stops the drift at the source.
Common use cases
- Agency onboarding a new client: auditing their existing naming patterns before establishing a shared convention.
- In-house team hygiene: checking a new campaign's UTM values against the team's lowercase-hyphen standard before it ships.
- Pre-launch: validating a batch of values pulled from a naming spreadsheet before campaign build.
- QA before spend: catching a stray capital letter or space in a UTM value before a paid link goes live.
Honest scope
This flags issues and suggests a slugified fix — it does not rewrite production links for you. Fails include uppercase, spaces, underscores, and characters outside
a-z0-9-hyphen segments. Rebuild flagged links with UTM Builder using the suggested values.Where do you browse more marketing tools tools?
