UTM builder: tag campaign links for GA4

Short tags on the end of a link, namely utm_source, utm_medium, utm_campaign and a few optional extras, that let Google Analytics record where a visitor came from. Without them, a click from an Instagram story, one from a WhatsApp message and one from a newsletter can all end up looking identical.

Three of them: source, medium and campaign. The rest are optional. Content distinguishes two links inside the same campaign, term holds a paid search keyword, and campaign ID only matters if you bring cost data into GA4.

Almost always a capital letter or a space. Analytics reads case exactly, so Instagram and instagram become two sources, and Ramadan Sale and ramadan_sale two campaigns. By default the builder makes everything lowercase and turns spaces into underscores.

GA4 files each visit under a channel based on its source and medium. If it does not recognise the medium, the visit goes to Unassigned. Stick to the standard values (social or paid_social for social media, email for newsletters, cpc for paid search), and check the channel the builder shows before you share the link.

They should, with a separate link for each creator. Use the platform as the source, social as the medium, your campaign name as the campaign and the creator's handle as the content, and Analytics will show which creator drove the visits and sales.

No. Tagging a link from one of your pages to another starts a fresh session and overwrites the visitor's real origin. Only tag links that bring people in from elsewhere.
