- 2Fill in campaign source, medium and name, plus optional term and content.
- 3Copy the generated UTM link and use it in your ads, emails or posts.
Accurate attribution
Tags traffic so Analytics can credit the right source, medium and campaign.
Consistent naming
Builds the parameters for you, reducing typos that fragment your reports.
Works anywhere
Produces a standard link you can drop into emails, ads, social posts or QR codes.
Tag a newsletter link for analytics
Building a campaign link for an email blast? Set the source to your newsletter name, the medium to email and the campaign to the send, then paste the tagged URL into your broadcast. Google Analytics 4 then reports those clicks as a distinct email campaign instead of lumping them under direct or referral traffic.
Track Google or Facebook ad clicks
Tag paid ad destination URLs so you can measure each channel's return. Use a source like google or facebook, a medium of cpc or paid_social, and the campaign name, then add utm_content to tell two creatives apart and utm_term for the keyword. Each variant lands as its own row in your reports for clean A/B comparison.
Build a trackable QR code or bio link
Need to know whether a flyer, packaging QR code or link-in-bio actually drives visits? Append UTM tags to the destination first, then turn that tagged URL into your QR code or paste it into a social profile. Offline scans and bio taps then show up as a named campaign in Analytics, so print and social finally get measurable credit.
UTM Link Builder — frequently asked questions
What do utm_source, utm_medium and utm_campaign mean?
Source names where the traffic comes from such as newsletter, medium is the channel type such as email or cpc, and campaign is the specific promotion name. Together they let Analytics group and compare your traffic.
Are UTM parameters case sensitive?
Yes. Google Analytics treats Email and email as separate values, which splits your data. Pick one consistent casing, usually lowercase, and apply it across every link.
Do UTM tags affect my SEO?
They do not help or hurt rankings directly, but you should avoid adding them to internal links since that can muddy your reports. Use UTMs mainly on external campaign links.
