Frequently Asked Questions
What are UTM parameters?▼
UTM (Urchin Tracking Module) parameters are tags added to a URL that tell Google Analytics where traffic came from. When a user clicks the link, GA records the campaign data. There are 5 parameters: utm_source, utm_medium, utm_campaign, utm_term, and utm_content.
What is utm_source vs utm_medium?▼
utm_source identifies where the traffic comes from (google, newsletter, facebook). utm_medium identifies the marketing channel type (cpc, email, social, organic). Think of source as 'who sent them' and medium as 'how they got there.'
Do UTM parameters affect SEO?▼
No. UTM parameters are not seen by Googlebot's ranking algorithms. However, if UTM-tagged URLs get indexed, they can create duplicate content issues. Use canonical tags to point to the clean URL, and consider adding UTM patterns to your robots.txt disallow rules.
Are UTM parameters case-sensitive?▼
Yes — in Google Analytics 4, utm_source=Google and utm_source=google appear as separate sources. Use lowercase consistently and avoid spaces (use underscores or hyphens). Inconsistent casing is the most common UTM tracking mistake.
