Frequently Asked Questions

What are UTM parameters?

UTM parameters are tags added to URLs that help you track which campaigns, sources, and mediums drive traffic to your website.

Which UTM parameters are required?

Only utm_source is required. utm_medium, utm_campaign, utm_term, and utm_content are optional but recommended for detailed tracking.

Can I shorten UTM links?

Yes! Create a free MASK account to convert long UTM URLs into short links with click analytics. Branded links with your own domain are available on the Growth plan.

How do I track UTM performance?

Use Google Analytics or similar tools to view UTM data. With MASK, you also get click-level analytics on your shortened links.

Is this UTM builder free?

It's free with a MASK account. Sign up free to build UTM-tagged campaign URLs, all saved to your dashboard. Saved links count toward your plan's link limit.
