How do I track UTM links in Google Analytics 4?

GA4 tracks UTM parameters automatically. Go to Reports → Acquisition → Traffic acquisition to see your UTM-tagged campaigns. Each combination of utm_source/utm_medium/utm_campaign appears as its own row. For first-touch attribution, look at the "First user source/medium" dimension. For last-click, use "Session source/medium". GA4 also stores utm_content and utm_term, which you can find under User attributes → Traffic sources, or by building a custom exploration with these dimensions.

What's the difference between utm_source and utm_medium?

utm_source identifies where the traffic comes from (google, facebook, newsletter, etc.). utm_medium identifies how it arrived (cpc, email, social, organic). A Google AdWords click would have utm_source=google and utm_medium=cpc. A link from your email newsletter would have utm_source=newsletter and utm_medium=email. The pair forms your "Session source/medium" report in Google Analytics — one of the most-used reports for campaign analysis.

Can UTM parameters affect SEO?

Generally no, but there's nuance. Google has stated that utm_* parameters don't directly affect ranking. However, having the same UTM-tagged URL appear on multiple pages can create duplicate content signals. Best practice: canonical-tag your UTM URLs back to the clean URL. Most CMS systems do this automatically. Also: avoid putting UTM parameters on internal links from your own site — use them only for external campaigns where you need to track referral source.

What's a UTM campaign vs a UTM source?

utm_campaign identifies the specific promotion (spring_sale, black_friday_2026, product_launch). utm_source identifies the platform (facebook, twitter, google). A single campaign might run across multiple sources — utm_campaign=spring_sale + utm_source=facebook AND utm_campaign=spring_sale + utm_source=email. In Google Analytics, you can roll up results across all sources for one campaign using the Campaign dimension, or compare performance across sources within one campaign.

How long can UTM parameters be?

Google Analytics doesn't enforce a hard limit, but: keep them under 100 characters total. URLs over 2,048 characters may break in some clients (email clients especially). Use lowercase to avoid splitting data ("Email" and "email" become two separate sources). Use dashes or underscores for multi-word values (utm_campaign=spring_sale_2026, not utm_campaign=Spring Sale 2026). And never put PII (email addresses, names) in UTMs — that breaks GDPR.
