UTM builder
Tag a link so your analytics knows which newsletter, post or ad sent the visit. Nothing you type here is saved.
Enter the page you're linking to.
Naming tips
Pick lowercase names and stick to them. Most analytics tools treat "Newsletter" and "newsletter" as two sources.
Source is who sent the visit, medium is how. A monthly email is
source newsletter, medium email; a post on Bluesky is source bluesky, medium social.
Use the usual mediums. Hark groups
email under Email
, social under Social
, cpc under Paid
, referral under Referral
. Other tools recognise the same words.
Don't tag links between your own pages. The visit gets credited to your tag instead of wherever the visitor really came from.
See which campaigns bring people in, live.
Hark shows every UTM source, medium and campaign on one page, without cookies. From $5 a month.
