UTM Parameters: How to Measure Your Digital Campaigns

UTM parameters are tags added to the end of a URL to identify where a visit came from. Used well, they let you compare campaigns from Instagram, email, WhatsApp, or other channels in Google Analytics. They don’t improve a campaign on their own: they help you tie every click to a source, a medium, and a specific initiative.

What UTM parameters are and what they’re for

A tagged URL can look like this:

https://tusitio.com/cotizar?utm_source=instagram&utm_medium=social&utm_campaign=regreso_clases

Each part answers a question:

• utm_source: which platform did the visit come from? Examples: instagram, newsletter, or google.
• utm_medium: what type of channel was used? Examples: social, email, or cpc.
• utm_campaign: which campaign does it belong to? Example: regreso_clases.
• utm_content: distinguishes versions of the same ad, button, or creative.
• utm_term: can identify a search term when you need it.

Google explains that these values show up in the acquisition reports when the link sends traffic to a site with Analytics set up. See the official guide to building campaign URLs.

How to build UTM links without messing up your data

Start with a simple convention and always stick to it. Define the values in lowercase, avoid spaces, and settle on a stable name for each channel. instagram and Instagram can end up as separate values, because capitalization matters.

Follow this process:

1. Choose the destination page. Send the person to the exact page that answers the offer, which isn’t always the home page.
2. Define the source and medium. For an Instagram story you could use utm_source=instagram and utm_medium=social.
3. Name the campaign. Use something understandable, like consulta_julio, and keep the same name across all of its channels.
4. Tell variants apart. If you’re testing two buttons, add utm_content=boton_a and utm_content=boton_b.
5. Test the link. Open it in another browser and confirm that it loads the right page.
6. Log it. Save the destination, campaign, source, medium, content, and date in a shared sheet.

If the URL ends up long, you can create a practical version with the Nexlab URL shortener after adding the UTMs. Test the short version too before you publish it.

Example of UTM parameters for a campaign

Imagine a clinic offers an assessment and shares the same page in an email and a social post. It keeps utm_campaign=evaluacion_julio, but changes the source and the medium:

• Email: utm_source=clientes&utm_medium=email
• Instagram: utm_source=instagram&utm_medium=social

That way it can compare which channel brought visits to the page. And if it also records a conversion —a form submission, for example— it can judge which traffic produced useful actions, not just clicks.

How to measure a campaign from your website

In Google Analytics, open the traffic acquisition report and compare campaign, source, and medium. Then cross those visits with the action that matters to the business: a request, a booking, a purchase, or a contact.

The destination page has to hold up the promise of the ad, explain the offer, and show a clear next step. If you need a structure ready to receive campaigns, review Nexlab’s website options for businesses, from a simple page to a multipage site, an online store, or tailored development.

Common mistakes with UTM parameters

Don’t use different names for the same campaign, and don’t switch between uppercase and lowercase. Save these tags for referral links and external campaigns, which is the use Google describes. And don’t read a click as a sale; define and measure the final action.

Frequently asked questions

What are UTM parameters?

They’re values added to a URL to identify the source, the medium, the campaign and, when needed, the content variant that generated a visit.

Which UTM parameters should I use?

For basic measurement, define at least source, medium, and campaign. Add content to compare variants, and term when it makes sense for paid search.

Where do I see UTMs in Google Analytics?

In the traffic acquisition reports you can look up dimensions like session source, medium, and campaign.

Can I shorten a link with UTMs?

Yes. First build the full URL with its parameters, then shorten it and check that the redirect keeps both the destination and the tags.

Measure every campaign with a clear rule

UTM parameters work when the whole team uses the same names and connects traffic to a real action. Start with one campaign, document its links, and review the results. A clear website will give you a destination where that information turns into inquiries, bookings, or sales.
