UTM parameters are tags you add to a URL to tell your analytics tool exactly where a visitor came from.
What are UTM parameters?
UTM parameters are short text tags added to the end of a URL that tell your analytics tool exactly where a visitor came from. When someone clicks a tagged link, those tags travel with them into Google Analytics, so you can see which campaign, channel, and specific ad or email produced the visit — and, if you connect a CRM, which ones produced actual leads and revenue.
“UTM” stands for Urchin Tracking Module, named after Urchin, the analytics company Google bought to build Google Analytics. The tags have been the universal standard for campaign tracking ever since, and every serious analytics platform reads them.
The five UTM parameters
There are exactly five standard UTM parameters. Three are required for clean reporting; two are optional and mostly useful for paid search and A/B testing.
utm_source (required)
The specific platform or site that sent the traffic: google, facebook, newsletter, linkedin. Answer the question “where exactly did this click come from?”
utm_medium (required)
The category of marketing the link belongs to: cpc (paid ads), email, social, referral, affiliate. Answer the question “what type of channel was it?”
utm_campaign (required)
The named campaign or promotion the link is part of: summer_sale_2026, product_launch, webinar_july. This groups every link across every channel that belongs to the same initiative.
utm_term (optional)
The paid keyword, used almost exclusively for search ad campaigns: whatsapp+crm. Most teams let their ad platform populate this automatically.
utm_content (optional)
Which specific link or creative was clicked when two point to the same place: header_cta vs footer_cta. This is what makes A/B testing measurable.
utm_source vs utm_medium: the difference that trips everyone up
Read together, source and medium form a sentence. A visit came from facebook (source) via a paid_social ad (medium). Or from google (source) via a cpc ad (medium). Or from mailchimp (source) via an email (medium). The source is the named place; the medium is the type of marketing. Get these two consistent and 90% of your reporting problems disappear.
UTM examples by channel
Here is a starter set you can copy. The key is consistency, not perfection — pick these values and use them the same way every time.
| Channel | utm_source | utm_medium |
|---|---|---|
| Google Ads | cpc | |
| Facebook / Instagram ads | paid_social | |
| Organic LinkedIn post | social | |
| Email newsletter | newsletter | |
| WhatsApp broadcast | social | |
| Partner / affiliate link | partner_name | affiliate |
Do UTMs work with Google analytics 4?
Yes — GA4 reads all five standard parameters automatically with zero setup. Tagged traffic populates the Session source, Session medium, and Session campaign dimensions under Reports → Acquisition → Traffic acquisition. GA4 also supports newer parameters like utm_source_platform, but the classic five are all most teams ever need.
The biggest mistake: stopping at the click
UTM parameters tell you which campaign earned the click. They do not, on their own, tell you which campaign earned the revenue — and clicks are a poor proxy for revenue. The campaign with the most clicks is often not the one with the most closed deals.
To close that loop, the UTM attribution has to follow the visitor into your CRM. When a tagged visitor becomes a lead in SkedX CRM or submits a SkedX Form, the source, medium, and campaign are stored on the lead record. That means you can report pipeline and closed revenue by campaign — not just sessions and bounce rate. That is the difference between “Facebook drove 4,000 clicks” and “Facebook drove ₹6 lakh in closed deals.”
Next steps
Start by tagging every external link that points to your site — ads, email links, social posts, partner placements. Keep a shared spreadsheet of approved source and medium values so your whole team tags the same way. Then read our companion guide on UTM naming conventions to lock in a framework that keeps your reports clean as you scale.
