UTM Link Builder

Build campaign tracking URLs with correctly formatted UTM parameters, so Google Analytics attributes traffic to the right source every time.

Why use our UTM Link Builder

Correct parameters, every time

utm_source, utm_medium, and utm_campaign are required for GA4 to attribute traffic correctly, a typo in any of them silently breaks tracking for that link.

Instant, updates live

Fill in the fields and the URL builds itself, no submit button, no waiting.

Properly URL-encoded

Spaces and special characters in your campaign or content values are encoded correctly, not left broken in the final URL.

100% local, nothing uploaded

Built entirely in your browser, no server involved.

Real UTM Link Builder example: before vs. after

Sending a newsletter link without tracking parameters, making it impossible to see how much traffic actually came from it.

Before · Before

Attributed sessions

A plain link with no UTM parameters shows up as direct or referral traffic, not tied to the specific campaign.

After · After

342

Attributed sessions

Same link, tagged with utm_source=newsletter, now clearly visible as its own traffic source in GA4.

Frequently Asked Questions

Which UTM parameters are actually required?

utm_source, utm_medium, and utm_campaign are the three GA4 needs for basic attribution. utm_term and utm_content are optional, useful for tracking specific keywords or A/B testing different link placements.

Does capitalization matter in UTM values?

GA4 treats utm_source=Newsletter and utm_source=newsletter as two different values, be consistent with casing across all your campaign links to avoid fragmenting your data.

Will UTM parameters affect my page's SEO?

Not directly, but a URL with UTM parameters is technically a different URL than the clean version. Make sure the page has a self-referencing canonical tag pointing to the clean URL to avoid any duplicate content ambiguity.

Can I use this for social media links too?

Yes, UTM parameters work on any link regardless of platform, social posts, email newsletters, paid ads, or QR codes.
