Add campaign parameters to a URL. To split a finished link apart, use the URL parser
utm_source Mediumutm_medium Campaignutm_campaign Termutm_term Contentutm_content IDutm_id Campaign links carry utm_source, utm_medium, utm_campaign and a few optional fields. This page writes those query parameters onto a page URL. Splitting a URL you already have is the URL parser.
https://example.com/page?utm_source=newsletter&utm_medium=email&utm_campaign=spring&utm_term=shoes&utm_content=logo&utm_id=42.The page must be an absolute URL, including the scheme. Values are encoded with the URL query rules, so a space becomes a plus or %20. Parameter names stay lowercase as written in the form.
Lowercase the values applies to the six utm values only. Filling a field again replaces the previous value of that name.
The page URL has to include a scheme, such as https://.
An empty field is omitted, and a parameter already on the URL with that name is removed.
