UTM parameters are small tags added to the end of a URL, letting marketers track exactly which specific source, campaign, or channel actually drove a given visitor to a website. They're an essential part of accurately measuring marketing performance across different channels.

  • utm_source — identifies the platform a visitor came from (e.g. "facebook")
  • utm_medium — identifies the general marketing medium (e.g. "social" or "email")
  • utm_campaign — identifies the specific campaign name
  • utm_term — identifies specific paid keyword terms, used mainly for paid search
  • utm_content — differentiates between multiple similar ads or links within the same campaign

A link like `ferdy.com/?utm_source=newsletter&utm_medium=email&utm_campaign=july_promo` tells Google Analytics precisely that a given visit came from a newsletter, through the email medium, as part of a specific July promotional campaign.

  • Reveal exactly which specific marketing efforts are genuinely driving results
  • Enable accurate comparison between different campaigns and channels
  • Support genuinely informed, data-driven decisions about where to focus marketing effort

Google's own Campaign URL Builder offers a simple, free way to generate correctly formatted UTM links, ensuring consistency across every campaign a marketer runs.
