What is a UTM parameter and why does it matter?

A UTM parameter is a snippet of text added to a URL that tells analytics tools like Google Analytics where a visitor came from. Without them, most referral traffic appears as direct or unknown, making campaign measurement nearly impossible.

Is the UTM builder completely free?

Yes. The tool is free with no account, subscription, or usage limits required.

Are my URLs kept private?

All processing happens in your browser. The URLs and parameters you enter are never sent to or stored on our servers.

Should I use lowercase for UTM values?

Yes. Google Analytics treats source values as case-sensitive, so Facebook and facebook would appear as two separate sources. Sticking to lowercase keeps your reports consistent.

Which UTM parameters are required?

Only utm_source is strictly required, but adding utm_medium and utm_campaign gives your reports meaningful segmentation from day one.

Can UTM parameters hurt my SEO?

UTM links do not directly affect search rankings, but using them on internal links can cause duplicate content issues if canonical tags are not set correctly. Keep UTM parameters for external campaigns only.

Can I create multiple UTM links for one campaign?

Absolutely. You can generate as many links as you need, each with different source, medium, or content values, allowing granular tracking across every channel.
