UTM link builder — know exactly which channel brings customers
The same destination page, but a separate link for each channel: Google Analytics 4 reads the UTM parameters and separates visitors from Facebook, Zalo, TikTok, or email. Pick a channel template, name the campaign, and copy the link — done.

How to use
- Paste the destination link (a product page, a landing page, and so on).
- Click a channel template to fill in the source and medium, or type your own.
- Give the campaign a short, lowercase, accent-free name — e.g. grand-opening-oct.
- Copy the link and use that exact link for the matching channel.

Where do I see the numbers after adding UTMs?
In Google Analytics 4: Reports → Acquisition → Traffic acquisition, then the Session source / medium or Session campaign dimension.
Why use lowercase letters?
GA4 is case-sensitive: "Facebook" and "facebook" become two different sources, splitting your numbers in two. The tool warns you when it spots an uppercase letter.
Do UTM links affect SEO?
No, as long as you only use them for ads, posts, and email. Do not attach UTMs to internal links between pages of your own website.
The link is too long — can I shorten it?
Yes — shorten it with a link-shortening service after you build it; the UTM parameters stay intact when someone clicks through.
