Most GA4 accounts share the same quiet problem: a growing share of campaign traffic lands in Unassigned, and nobody notices until a report is wrong. The cause is almost always the URL. Someone typed utm_medium by hand, someone else invented a new naming style, and GA4's channel rules never matched any of it.
Trakr fixes this at the source. Instead of a blank form, your team gets a guided flow: pick from dropdowns, follow your naming rules, and watch the URL check itself against GA4 channel definitions before anyone copies it. A green badge means the URL will land in the channel you intended. A red badge tells you what to fix while the campaign is still on your screen.
You define the structure once: which fields make up utm_campaign, in what order, with which separators and allowed values. Then you share that configuration with your team or your agency, and everyone builds URLs with the same rules. Workspaces keep client data separated, the bulk builder creates a full channel set in one pass, and every generated URL lands in a searchable history.
For automation, Pro includes a full REST API and a native MCP connector, so your server-side tagging setup or your AI assistant can read and create campaign links directly. Trakr was built by a digital analytics consultant after 16 years of cleaning up UTM chaos in enterprise accounts.
The Free plan is the full builder, and the first URL needs no signup. Pro is 29 EUR per month for teams: shared configurations, workspaces, full history, API and MCP access.
