The gold standard for
data-driven marketing teams.
A guided flow that builds GA4-compliant campaign URLs from dropdowns and preconfigured rules. Pick a channel, click through, get a correct URL. Every time.
Your campaigns are breaking in GA4. You just don't see it yet.
Every enterprise we've worked with has the same symptoms. They only show up when someone checks the channel report and half the traffic sits in Unassigned.
Every agency uses different naming
Three agencies, three naming conventions. One writes "google / cpc," the next writes "gdn / banner," and the third invents something new every quarter. Your GA4 channel groupings break.
Nobody updates the UTMs after launch
Source and medium get set once when the campaign launches. When the creative changes, the channel changes, or the landing page moves, the UTMs stay frozen. GA4 reports stale data.
Half your traffic lands in Unassigned
Campaigns that should show as "Paid Social" or "Display" end up in Unassigned because the source/medium combination doesn't match GA4's channel definitions. The data is there. The mapping broke.
REAL IMPACT
What teams lose every year to broken UTMs.
Numbers from real agency interviews. Every team we talked to had the same story.
150h
wasted per year
On campaign URL creation alone. Large campaigns with 20+ publishers take 3 hours when a guided flow would take 30 minutes.
€13,500
in billable hours burned
6-7 email rounds per campaign to align on naming, apply changes, and confirm the final URLs. That grunt work adds up to five figures a year.
100%
trust in your channel report
When half your traffic sits in Unassigned or lands in the wrong channel, every number in your report is a guess.
Based on interviews with agencies managing enterprise GA4 campaign tracking.
WHO BUILT THIS
Built by someone who spent 16 years watching campaigns fall into Unassigned.
Trakr is not a weekend project. It is the distillation of every UTM failure I have seen across 50+ enterprise analytics projects, and the tool I built to make sure it stops happening.

I have built analytics departments from scratch at Metro AG, designed tracking strategies for Zürcher Kantonalbank's entire digital ecosystem, and led Mazda Europe's GA4 migration. Every project, same story: UTMs are a mess, channels break, nobody has a tool that does it right. So I built one.

Every other tool gives you empty text fields. Trakr gives you a guided flow with preconfigured rules.
Guided flow, not a blank form
Works like a checkout funnel. Each step asks one question, validates your input, and moves you forward. You pick from dropdowns, not type into text fields. The wizard adapts to your configuration: add a parameter, a new step appears. Remove one, it disappears.
Channel selection drives source/medium
Pick "Paid Social" and the tool knows the correct source/medium for GA4. Pick "Display" and it sets the right combination. No guessing, no checking the documentation, no Unassigned in your channel report.
Configurable taxonomy and syntax
Define which fields go into each UTM parameter, in what order, with what separator. Your utm_campaign becomes [country]_[product]_[objective]. Set it once, everyone follows it. No naming convention drift.
Build once, share with your agency
You build the configuration: your taxonomy, your channel definitions, your dropdown values. Then share access with your agency. They use your tool, with your rules, to create URLs for your campaigns. No briefing documents. No "please use this spreadsheet."
One complete URL, not just UTMs
Campaign URLs often need parameters for Salesforce, CRMs, or internal attribution. Trakr includes those in the same flow.
GA4 compliance check at creation time
Every URL validated against GA4 channel definitions before export. Green badge: correct channel. Red badge: fix before launch.

ON THE ROADMAP
MCP connector MCP
Let your AI agent build every URL
Configure your taxonomy once in Trakr. Then let Claude, ChatGPT, or any MCP-compatible agent create campaign URLs on your behalf. Same channel rules, same syntax validation, same governance. The agent reads your configuration, you stay in control.
Trakr is a campaign URL builder designed for GA4. You set up your naming conventions, channel definitions, and field structure once. After that, anyone on your team follows a guided flow and gets a correctly formatted URL with the right source, medium, and campaign parameters. Every URL is validated against GA4's channel definitions before you copy it.
Google's tool gives you five empty text fields. You type whatever you want, hit generate, and hope the source/medium combination ends up in the right GA4 channel. There's no validation, no naming convention enforcement, and no way to share a configuration with your team. Trakr replaces that with a step-by-step flow. You pick a channel, the tool sets the correct source and medium, and you fill in the rest from preconfigured fields. The output follows your naming convention every time, and every URL is checked against GA4 channel definitions before you copy it.
You start by picking a GA4 channel, like "Paid Social" or "Display." That selection sets your source and medium automatically based on GA4's channel definitions. Then you move through a series of steps: country, campaign subject, ad format, funnel stage, and whatever else your configuration includes. Each field can be a dropdown, a text input, or a date picker, depending on how you set it up. The values you pick are assembled into your utm_campaign, utm_content, and any other UTM parameters following the naming syntax you defined during setup. At the end you get a full URL with all parameters, validated against GA4.
Yes. You build the configuration once: your channels, your field values, your naming syntax, your field structure. Then you share it with your agency. They open the same tool, see your rules, and build URLs from your configuration. No briefing documents, no "please use this spreadsheet," no back-and-forth about which source to use for TikTok campaigns. They follow the flow, and the output matches your conventions.
Currently, yes. Trakr is built for marketing teams who track campaigns in Google Analytics 4. UTM parameters define how campaign information lands in GA4, and two of those parameters (source and medium) determine which channel your traffic gets assigned to. That's the core problem we solve: making sure every URL you build actually maps to the right channel and you have the campaign information you need in GA4 to judge your campaign performance. If there's demand for other platforms, we'll extend support.
Add them. In Trakr, you can define custom parameters for whatever your stack needs: Salesforce campaign IDs, internal attribution tags, CRM identifiers, ad platform click IDs. They show up as steps in the same guided flow, and the values end up in the final URL alongside your UTM parameters. One tool, one URL, everything in it.
MCP stands for Model Context Protocol. It's a standard that lets AI tools like Claude or ChatGPT connect to external applications. We're building an MCP connector for Trakr so you can describe what you need in plain language and get a validated URL back. Same rules, same naming convention, no manual steps. It's on the roadmap, not in the first release.
Q3 2026. The core product is built and in testing. Join the waitlist and we'll let you know when early access opens.
