What is a UTM link and how do I set it up for influencer campaigns?

UTM links explained simply: A UTM link is your normal website URL with tracking tags added at the end. Example: yourbrand.com/product?utm_source=instagram&utm_medium=influencer&utm_campaign=march2026&utm_content=sneha_creator. When someone clicks it, Google Analytics records exactly who sent them. How to create one: Google has a free UTM Builder tool — search "Google Campaign URL Builder." You fill in: source (instagram), medium (influencer), campaign name, and creator name. Give each creator a unique link. After 2 weeks, check Google Analytics → Acquisition → Campaigns to see which creator drove traffic and purchases. Takes 5 minutes to set up and completely changes what you can measure.
