Using UTM tags
What UTM parameters are
UTM parameters are short tags added to the end of a URL, such as ?utm_source=instagram&utm_medium=social&utm_campaign=spring_sale. When someone clicks the link, analytics tools like Google Analytics read the tags and report the visit under that source, medium and campaign. The five standard parameters are:
- utm_source: where the click came from, for example
instagram,newsletterorgoogle. - utm_medium: the type of channel, for example
social,email,cpcorqr. - utm_campaign: the campaign or promotion name, for example
spring_sale. - utm_term: the keyword, mainly for paid search (optional).
- utm_content: tells apart links in the same campaign, such as two ad variants (optional).
Source, medium and campaign are the ones to always fill in.
Naming rules that keep your reports clean
- Use lowercase everywhere.
Instagramandinstagramare reported as two different sources. - Use underscores or hyphens instead of spaces, and pick one.
- Agree on a fixed list of sources and mediums in your team and reuse it.
- Keep campaign names short and dated if you repeat them, for example
spring_sale_2026. - Never put personal data (names, emails, order numbers) in a UTM tag; the URL is visible and ends up in logs.
- Do not tag links inside your own website. Internal tagged links can overwrite the real source of a visit.
UTM tags and WhatsApp
A wa.me click-to-chat link opens WhatsApp, which does not read UTM tags. To measure where WhatsApp chats come from, tag the page URL that holds your WhatsApp button (in your ad, post or email), and track the click on that button in your analytics. You can also use a different pre-filled message per placement with the WhatsApp link generator to tell chats apart inside your inbox.
