How to use this tool
Choose names you can keep using
Document one naming convention and use it across your team. Differences in case and spelling can fragment reports. The normalisation option lowercases the values you enter and turns whitespace into underscores; switch it off when you need to preserve exact values.
Check the full tracking setup
UTM tags label a link; they do not install analytics or prove that a conversion was tracked. For Google Ads, review auto-tagging and your GA4 link before adding manual tags. Avoid tagging internal site links because campaign tags are intended to identify incoming traffic. Never put personal information in a campaign URL.
A worked example
A campaign named autumn_launch on google with medium cpc adds ?utm_source=google&utm_medium=cpc&utm_campaign=autumn_launch to a plain destination URL. Existing query parameters are joined with & instead.
