    How to use the UTM link builder

    1. Paste the page you want people to land on.
    2. Pick a quick fill, or type a source (where the link lives) and medium (the kind of channel).
    3. Name the campaign, for example spring-launch-2026.
    4. Copy the tagged link and use it in that one place only. Make a new one for each post, email or listing.

    What each UTM tag means

    • utm_source: the site or sender, like linkedin, facebook, newsletter or producthunt.
    • utm_medium: the channel type, like social, paid_social, email, referral or cpc.
    • utm_campaign: the promotion, launch or month the link belongs to.
    • utm_term: optional, usually the paid search keyword.
    • utm_content: optional, to tell apart two links in the same post or email.

    Naming rules that keep reports clean

    • Use lowercase. Most analytics tools treat Facebook and facebook as two different sources.
    • Pick one name per place and stick to it. Write them down so everyone on your team uses the same ones.
    • Use the standard mediums. Google Analytics 4 sorts traffic into channels like Email and Organic Social from the medium, so email and social land in the right buckets.
    • Don't tag links between your own pages. UTM tags are for links on other sites, emails and ads. Tagging internal links can overwrite where a visitor really came from.

    Questions

    What is a UTM link?

    A normal link with a few extra tags on the end, like ?utm_source=linkedin. Analytics tools read the tags and record where the visit came from. The page itself works the same.

    Do UTM tags hurt SEO?

    Not when they're used on links from other sites, emails and ads. Search engines generally ignore them, especially when your pages have a canonical tag. Avoid them on links between your own pages.

    Where do I see the results?

    In Google Analytics 4, open Reports, then Acquisition, then Traffic acquisition, and switch the table to Session source / medium or Session campaign. Other analytics tools have a similar campaign report.

    Is anything I type saved?

    Only on your device. The tool runs in your browser, and the links you copy are kept in this browser's storage so you can find them again. Clear the list any time.
