About the UTM Campaign Link Builder

When someone clicks a link to your site, your analytics can see that they arrived — but not always why. UTM parameters fix that. They're small tags added to the end of a URL that tell Google Analytics (and most other analytics tools) exactly which campaign, channel, and piece of content sent each visitor. This builder assembles those tags correctly so your reports stay clean and comparable.

It all runs in your browser. Your URLs and saved history live only on your device — nothing is sent to a server, so even pre-launch landing pages and private campaigns stay confidential.

What each parameter means

utm_source — where the visit comes from: google, newsletter, facebook.
utm_medium — the channel type: cpc, email, social, referral.
utm_campaign — the specific promotion: spring_sale_2026.
utm_term — paid-search keywords (optional).
utm_content — distinguishes two links in the same campaign, like an A/B test or two CTAs (optional).
utm_id — a campaign ID used by GA4 to group everything together (optional).

Best practices baked in

Consistent casing — UTM values are case-sensitive, so Email and email become two different rows in your reports. The builder can force values to lowercase to keep them tidy.
Proper encoding — spaces and special characters are URL-encoded automatically, so your links never break.
Existing parameters preserved — if your URL already has query parameters, they're kept; only the UTM tags are added or updated.
A saved history — every link you copy or save is stored locally so you can reuse and stay consistent across a campaign.

Share it anywhere

Copy the finished link into an email, ad, social post, or bio — or generate a QR code to print on flyers, packaging, or event signage and track offline-to-online traffic just as precisely.

No account, no upload, no tracking of you — build the link, copy it, measure what works.
