UTM Link Builder
Build campaign tracking URLs with correctly-encoded utm_source, utm_medium, and utm_campaign tags.
About this tool
A UTM link builder adds tracking parameters to a URL so your analytics tool can tell exactly where a visitor came from. Fill in the campaign details and it appends tidy, correctly-encoded utm_* parameters to your link — ready to paste into an ad, an email, or a social post.
What each parameter means
- utm_source — where the traffic comes from: google, facebook, newsletter.
- utm_medium — the channel type: cpc, social, email, banner.
- utm_campaign — the specific campaign: summer_sale, launch_2026.
- utm_term and utm_content — optional: paid keywords, and which link or creative was clicked for A/B tests.
Why consistency matters
Analytics treats Facebook and facebook as two different sources, which splits your reports. Pick a lower-case convention and stick to it across every campaign. This builder URL-encodes spaces and symbols for you, so a value like "summer sale" becomes a valid parameter automatically.
The link is assembled in your browser using the standard URL API; nothing is sent anywhere. To shorten or encode part of the link further, see the URL Encoder & Decoder.
Frequently asked questions
What is a UTM link?
A UTM link is a normal URL with extra utm_ parameters added. They tell analytics tools like Google Analytics which campaign, source, and medium a visitor came from.
Which UTM parameters are required?
utm_source, utm_medium, and utm_campaign are the core three. utm_term and utm_content are optional, used mainly for paid keywords and A/B testing creatives.
Should UTM values be uppercase or lowercase?
Use lowercase consistently. Analytics treats "Facebook" and "facebook" as different sources, which fragments your reports.
Does it handle spaces and special characters?
Yes. Values are URL-encoded automatically, so a campaign name with spaces or symbols produces a valid, working link.
Is my URL sent anywhere?
No. The link is built entirely in your browser.
