Build a trackable campaign URL by adding standard UTM parameters to any link. Enter your base URL and campaign details, and the tool assembles a tagged URL you can paste into ads, emails, or social posts. Values are percent-encoded so the link stays valid.
How this is calculated
The tool appends the standard utm_source, utm_medium, and utm_campaign query parameters, plus optional utm_term and utm_content when provided. Each value is percent-encoded and joined with the existing query string so your analytics platform can attribute the visit to the campaign.
How to use
- Enter the base URL you want to track.
- Fill in the source, medium, and campaign fields.
- Add optional term and content values, then copy the generated URL.
Examples
- Paid search:
example.com + google/cpc/summer_sale → ?utm_source=google&utm_medium=cpc&utm_campaign=summer_sale - Existing query:
page?id=5 keeps its query and appends UTM tags with &
FAQ
- Which fields are required?
- The base URL, source, medium, and campaign are required. Term and content are optional and only added when filled in.
- Why must the URL start with http:// or https://?
- Analytics tools expect a full, absolute URL. The builder rejects links that do not begin with a valid scheme.
- How are spaces and symbols handled?
- Each parameter value is percent-encoded, so spaces become %20 and the resulting URL stays valid.
