The same landing page can still show which source and which creative sent the visit, once the utm values are on the link.

The values are attached on this screen. The finished address is not stored by Kitharu.

01How to use it

Enter the URL, source, medium, and campaign name. An ad set is appended after the campaign.

Gender, age, interest, and region become utm_term. Keyword mode keeps only that word.
02What you get

Source Google Ads, medium paid social, campaign hotseller, and set broad become utm_source=google_ads, utm_medium=paid_social, and utm_campaign=hotseller|broad.

Leave gender and age empty and utm_term is left off.

utm_campaign hotseller|broad
03Worth knowing

If there is no scheme, https:// is added. A space or a percent sign in the host stops the link.

An empty optional field leaves that parameter off.

utm_campaign	hotseller\|broad
