Question 1

What are UTM parameters?

Accepted Answer

UTM (Urchin Tracking Module) parameters are tags added to a URL that help you track where your traffic comes from in Google Analytics. There are five parameters: source, medium, campaign, term, and content. They let you see exactly which social media post, email, or ad drove traffic to your site.

Question 2

Which UTM parameters are required?

Accepted Answer

Technically none are required for the URL to work, but utm_source and utm_medium are essential for meaningful tracking in Google Analytics. Without these, your traffic may show up as 'direct' or 'unassigned' — making it impossible to measure campaign performance.

Question 3

What's the difference between source and medium?

Accepted Answer

Source is where the traffic comes from (e.g., 'instagram', 'newsletter', 'google'). Medium is how it gets to you (e.g., 'social', 'email', 'cpc'). Think of it as: source = the specific platform, medium = the type of channel.

Question 4

Do UTM parameters affect SEO?

Accepted Answer

No. Google ignores UTM parameters for ranking purposes. However, it's best practice to use UTM links only for external campaigns (social, email, ads) — not for internal links on your own site, as that can mess up your analytics by overwriting the original traffic source.

Question 5

How do I view UTM data in Google Analytics?

Accepted Answer

In Google Analytics 4, go to Reports → Acquisition → Traffic Acquisition. You'll see your traffic broken down by source, medium, and campaign. You can also create custom explorations to analyze UTM data in more detail.
