Free online UTM link builder
This UTM link builder helps you create tagged campaign URLs so your analytics tool can tell exactly where your traffic comes from. Fill in your website address and the campaign details — source, medium, and name — and the finished link is assembled live below, with every value safely percent-encoded. It's ideal for newsletters, paid ads, social posts, and any link where you want to measure results. Everything runs in your browser, so nothing is uploaded.
How to build a UTM link
- Paste the destination page address into the Website URL field.
- Enter the campaign source, medium, and name — these three are required.
- Add an optional term or content value to tell similar links apart.
- Click Copy link to grab the finished URL for your campaign.
What the UTM parameters mean
Each utm_ parameter answers a different question.
utm_source names where the visit came from (for example, google
or newsletter), utm_medium describes the channel (email, cpc,
social), and utm_campaign labels the specific promotion. The
optional utm_term records a paid keyword, while
utm_content helps you A/B test two links that point to the same
page. To double-check how the finished address is put together, open it in the
URL parser.
Private and instant
Because the link is built entirely on your device, your campaign names and URLs are never sent to a server. There's no sign-up and no limit, so you can tag as many links as you like. Once your landing page is live, generate its social preview with the meta tag generator so shared links look their best.
