Build campaign-tagged URLs by adding UTM parameters (source, medium, campaign, term and content) to any link. Correct, consistent UTMs let Google Analytics and other tools attribute traffic and conversions to the right channel. The builder lowercases values and encodes them safely so your links never break.

Frequently asked questions
What do utm_source, utm_medium and utm_campaign mean?
Source is where the traffic comes from (e.g. newsletter), medium is the channel type (e.g. email, cpc), and campaign is the specific promotion (e.g. summer_sale).
Should UTM values be lowercase?
Yes. Analytics treats Email and email as different values, so keeping everything lowercase prevents your reports from splitting one channel into several.
Do UTM parameters affect SEO?
Used on links you share (ads, emails, social) they are fine. Avoid adding them to internal links you want indexed, since they can create duplicate URLs.
