UTM Link Builder
Build UTM links to separate traffic sources for blog, social, and email campaigns.
When do you use UTM?
When the same page link comes from different channels — Instagram, a blog, email — and you want to tell the performance apart, you add UTM parameters. Share the generated link on each channel and your analytics tool can break down visits and conversions by channel.
When to use it
- Social ads: use utm_source=instagram, utm_medium=cpc to track Instagram ad traffic separately.
- Newsletters: use utm_medium=email to separate clicks that came from email.
- Partnerships: use utm_source=partner_blog to track a specific blog partnership's results.
Naming tips & things to note
- Keep source as the platform (naver, google, instagram), medium as the format (social, cpc, email), and campaign as the campaign name (launch_2026).
- Always use lowercase and underscores (_) instead of spaces so your data doesn't split.
- Don't add UTM to internal links on your own site, and never put personal data in a link.
Frequently asked questions
What exactly are UTM parameters?
UTM is a tracking tag appended to a link. Adding utm_source, utm_medium, utm_campaign, and so on lets analytics tools like Google Analytics tell which channel or campaign a visit came from.
How do source, medium, and campaign differ?
source is the traffic platform (naver, google, instagram), medium is the format (social, cpc, email), and campaign is the campaign name (summer_sale, launch_2026). Filling all three consistently makes later comparison easy.
Is it case-sensitive?
Yes — analytics tools treat utm_source=Naver and naver as different values. Standardize on lowercase so your data doesn't split later.
Should I add UTM to internal links on my own site?
Not recommended. Adding UTM to internal links can break the existing session and distort the traffic source. Use UTM only for links coming into your site from outside.
Can I put personal data in the generated link?
No. UTM values are exposed in analytics tools and the URL, so never include names, emails, or phone numbers.
