Free UTM Builder and Checker helps marketers, bloggers, and businesses create clean campaign URLs, validate UTM parameters, identify common tracking issues, and check the expected GA4 channel before using a link.
I built this tool to make UTM tracking easier for marketers, bloggers, and small businesses. Creating campaign URLs is simple, but small formatting mistakes can make tracking inconsistent or harder to analyze. I wanted a free, browser-based tool that lets people build, check, and clean UTM URLs without sending their campaign data to a server.
