Build your tagged URL

Free tool

Build a tagged campaign URL

Paste your link, fill in the campaign fields, and copy a clean UTM-tagged URL. The output assembles live. Nothing leaves your browser.

Your tagged URL will appear here once you paste a link.

Tagged links only pay off if something reads them.

GoHighLevel ties every UTM-tagged click to the lead it became, so you see which campaign booked the call, not just which one got traffic.

What UTM tags do

A UTM tag is a small piece of text added to the end of a link. It does not change where the link goes. It only tells your analytics tool how the visitor arrived. Without tags, a lot of traffic lands in a vague "direct" or "referral" bucket, and you cannot tell which campaign earned it.

There are five tags. Source is where the traffic comes from, such as google or a newsletter. Medium is the channel type, such as cpc, email, or social. Campaign names the specific promotion. Term is for paid search keywords. Content tells near-identical links apart, like two buttons in the same email. Source, medium, and campaign are the three you will use most.

Once your links are tagged, your reports stop guessing. You can see that the spring email drove twice the sign-ups of the paid ad, and put your effort where it pays.

A short, honest guide to UTM conventions

Consistency beats cleverness. The single most important habit is using the same spelling and casing every time. facebook and Facebook become two separate rows in your reports, which makes one campaign look like two. The lowercase and trim toggle on this tool handles that for you.

Pick one naming scheme and write it down. Decide that medium is always email, not e-mail or newsletter, and that campaign names use underscores, not spaces. A one-page cheat sheet you actually follow is worth more than a perfect system you forget.

Never use UTMs on internal links. Tagging a link between two pages of your own site overwrites the visitor's original source and starts a new session, which corrupts your data. UTMs belong only on links pointing to your site from somewhere else.

Keep the values readable. You and your teammates will read these in reports for months. spring_sale_2026 is clear. sp_sl_26_v2 is a puzzle you will not remember.

Tips for cleaner campaign tracking

Build the link before you publish, not after. It is easy to forget tags once a post is live, and an untagged link cannot be fixed in your reports later.

Keep a simple log of the links you create, so two people do not invent two different campaign names for the same push.

Shorten tagged links for places where a long URL looks messy, like a printed flyer or a social bio, but keep the full tagged version on record.

Check your analytics a few days after launch to confirm the tags are landing in the right fields. Catching a typo early saves a month of split data.

From tagged click to tracked customer

UTM tags tell you which campaign sent the traffic. They do not, on their own, tell you which campaign produced a paying customer, because the click and the sale usually happen in different tools.

GoHighLevel ties each tagged click to the lead it becomes and follows that lead through to the booked call or the sale. Instead of knowing only which campaign got visits, you see which one actually filled the calendar, which is the number that matters.

Frequently asked questions

What is a UTM parameter?

A UTM parameter is a tag you add to a link so your analytics knows where the click came from. The five tags are source, medium, campaign, term, and content. When someone clicks a tagged link, those values show up in your reports.

What is the difference between utm_source and utm_medium?

Source is where the traffic comes from, like google, facebook, or a newsletter name. Medium is the type of channel, like cpc, email, or social. Source answers "who sent them" and medium answers "what kind of link it was".

Should I use UTMs on internal links?

No. Never put UTMs on links between pages of your own site. They overwrite the original source data and break your reporting by starting a new session. Use UTMs only on links coming from outside your site.

Why should I lowercase my UTM values?

Because analytics tools treat Facebook and facebook as two different sources. Inconsistent casing splits one campaign into several rows in your reports. The lowercase and trim toggle keeps everything consistent so your data stays clean.

Is the UTM builder free?

Yes. It is free, needs no signup, and runs entirely in your browser. Nothing you type is stored or sent anywhere.
