How to use the UTM Link Builder
- Enter one or more page URLs, or try the example.
- Fill in the source, medium and campaign name, and optionally content, term and campaign ID.
- Select Build links, then copy them or download them as CSV.
Supported files and limits
- Tags are written in lowercase with dashes for spaces by default, so "October Offer" and "october offer" are not reported separately.
- Existing UTM tags in a URL are replaced. Other parameters and #anchors are kept.
- A medium that Google Analytics does not recognise is pointed out, as those visits may show as Unassigned.
- Up to 5,000 URLs at a time.
Common questions
Which UTM parameters are required?
Use at least utm_source (where the link is, such as newsletter or facebook), utm_medium (the type of channel, such as email or cpc) and utm_campaign (the campaign name).
Should UTM tags be lowercase?
Yes. Analytics treats Email and email as different values, which splits your reports. Lowercase tags with dashes avoid this.
Can I use UTM tags on links within my own website?
No. On internal links they start a new session and replace the real source of the visit. Use them only on links from emails, ads, social posts and other websites.
Is anything sent to a server?
No. The links are built in your browser and nothing you enter is sent to our server or anyone else.
