How it works
The parameters
Source says where the visit comes from, medium the type of channel, and campaign the effort it belongs to. Term, content and id are optional and tell variants apart. The tool appends them as utm_ query parameters.
page?utm_source=…&utm_medium=…&utm_campaign=…
Keeping data clean
Analytics treats Email and email as two values. Lowercasing and swapping spaces for dashes or underscores keeps reports from splitting. Any query string or fragment already on the page is kept, and existing utm_ values are replaced.
