UTM Builder Generator – Create Campaign Tracking URLs
Create accurate UTM links in seconds — no setup, no hassle. This simple, no-code tool helps you build custom UTM codes in seconds so you can track your marketing campaigns with ease.
What are UTM parameters and why use them?
UTM parameters tag a link so analytics can attribute traffic and campaigns correctly. Core parameters include:
- utm_source: where the traffic came from (e.g., google, newsletter) - utm_medium: marketing channel (e.g., cpc, email, social) - utm_campaign: campaign name or initiative (e.g., spring_sale) - utm_term: optional keyword for paid search - utm_content: optional creative or A/B variant
Do I need to URL-encode UTM values?
Yes — values must be percent-encoded so spaces and special characters are safe. This tool encodes automatically using standard URL encoding.
Examples: - "Spring Sale" → "Spring%20Sale" - "a&b=c" → "a%26b%3Dc"
Note: URLs use %20 (not +) for spaces.
Will this work with existing query parameters?
Yes. Existing query parameters are preserved, and UTM keys are added or updated without breaking the URL.
Example: Input: https://example.com/page?a=1 + utm_source=newsletter Output: https://example.com/page?a=1&utm_source=newsletter
GA4 vs Universal Analytics — do UTMs differ?
No. Both GA4 and Universal Analytics read the same UTM keys. The reporting UI differs, but utm_source, utm_medium, utm_campaign, utm_term, and utm_content work the same for attribution. Use consistent naming conventions for clean reports.
Which UTM fields are required?
For reliable attribution, set at least:
- utm_source - utm_medium - utm_campaign
utm_term and utm_content are optional — add them only if relevant.
