How it works
The tool parses your URL, then sets each utm_* query parameter you filled in (replacing any existing value and keeping your other parameters). Values are percent-encoded, so spaces and symbols are safe. With the lowercase option on, “Spring Sale” becomes spring-sale.
A simple naming convention
| Channel | utm_source | utm_medium |
|---|---|---|
| Email newsletter | newsletter | |
| Organic Facebook post | social | |
| Instagram bio link | social | |
| Paid search ad | cpc | |
| WhatsApp broadcast | messaging |
Example
URL https://example.com/shop, source newsletter, medium email, campaign Spring Sale becomes:
https://example.com/shop?utm_source=newsletter&utm_medium=email&utm_campaign=spring-sale
Frequently asked questions
What are UTM parameters?
Tags added to a URL (utm_source, utm_medium, utm_campaign and optionally utm_term, utm_content and utm_id). Analytics tools such as Google Analytics read them to attribute visits to a campaign, channel or link.
Which UTM fields are required?
Source, medium and campaign are the core three and should be filled for every tagged link. Term and content are optional — content is useful to tell apart two links in the same email or post.
Should UTM values be lowercase?
Analytics tools generally treat values as case-sensitive, so “Facebook” and “facebook” can show up as separate sources. Pick a convention, such as lowercase with hyphens, and stick to it — this tool can enforce it.
Should I use UTM links on my own website?
No. Tagging internal links can overwrite the original source of a visit. Use UTMs only on links pointing to your site from elsewhere — emails, social posts, ads and partner sites.
