How to use this UTM link builder
- Website URL: The landing page you want to send traffic to.
- Source (utm_source): Identifies who sends the traffic (e.g. google, facebook, newsletter).
- Medium (utm_medium): The marketing channel (e.g. cpc, email, banner).
- Campaign (utm_campaign): The specific promotion name (e.g. black_friday_2026).
Best practices for tagged URLs
- Always use lowercase: GA4 is case-sensitive. "Email" and "email" will be tracked as two separate channels. Our generator converts automatically.
- Avoid spaces: Use underscores (_) or hyphens (-) to separate words.
- Don't tag internal links: Use UTMs only for external traffic arriving at your site, never for buttons navigating within your own page.
Frequently Asked Questions (FAQ)
Which UTM parameters are required?
According to Google's recommendations, every tagged link should include at least three parameters: utm_source (source), utm_medium (medium) and utm_campaign (campaign name).
Can I use capital letters or spaces in my UTMs?
Not recommended. Google Analytics is case-sensitive, so 'Facebook' and 'facebook' will appear as separate sources. Always use lowercase and replace spaces with hyphens or underscores.
Should I use UTMs on internal links within my site?
No. Using UTM parameters on internal links would overwrite the original source that brought the user to your site, losing true acquisition tracking.
