What the five UTM parameters mean
utm_source names who sent the traffic, such as google, facebook or newsletter. utm_medium names the channel type, such as cpc for paid search, email, social or display. utm_campaign names the promotion, for example spring_sale or free_audit. These three are the ones analytics tools rely on.
utm_term is optional and usually holds the paid keyword. utm_content is optional too and tells apart two links in the same campaign, such as the hero button and the footer link of one email, or two versions of an ad.
