UTM is a set of parameters added to a URL so analytics tools can identify the source, medium and campaign of a visit. Used consistently, UTM answers which content brings customers rather than just clicks.
UTM does not create accurate data on its own. You still need a naming convention, link checks and connected conversion events. If everyone writes tags their own way, one channel gets split across several rows in the report.
The 5 common UTM parameters
- utm_source: the specific source sending the traffic, such as a newsletter or a partner name.
- utm_medium: the channel type, such as email, social, referral or paid_social.
- utm_campaign: a consistent campaign name based on the goal or the period.
- utm_content: distinguishes the ad creative, the button or the content variant.
- utm_term: records the keyword group or targeting criteria when you genuinely need it.
Build a naming convention you can manage
- Use lower case and one consistent separator.
- No spaces, no accented characters and no per-person spelling variations.
- Names should describe the source and purpose but contain no personal data.
- Store every link in a shared sheet with an owner and a creation date.
- Define the list of valid values for source and medium.
An example link structure
https://example.com/san-pham?utm_source=newsletter&utm_medium=email&utm_campaign=ra_mat_thang_09&utm_content=nut_chinhNote: Never put an email address, phone number, customer name or sensitive data into URL parameters, because links show up in browsing history, server logs and third-party reports.
How to roll it out and check it
- 01
Build links from a standard template
Pick values from the agreed list instead of typing them freely each time.
- 02
Check the landing page
Open the link, confirm the page loads and that the parameters do not break a redirect or the checkout.
- 03
Check the report
Confirm the session appears under the correct source, medium and campaign in your analytics tool.
- 04
Attach conversions
Track sign-ups, enquiries, checkout starts and transactions to judge traffic quality.
How to read the report correctly
Compare campaigns by cost, conversions, revenue and profit rather than by visits alone. A channel may support the customer early in the journey without being the last touch, so also read the conversion paths and ask customers how they found you.
- Separate new and returning customers when judging performance.
- Check for conversion windows longer than a single session.
- Reconcile revenue with the order system rather than trusting one report.
- Note major changes to content, budget or landing pages.
