Traffic Sources & UTM Tracking
When a visitor submits your waitlist form, VOTLI automatically captures where they came from. This data appears in the Source column of your subscriber list and in the Traffic Sources breakdown on the dashboard.
What gets tracked
| Field | Description | Example |
|---|---|---|
utm_source |
The traffic source | google, twitter, newsletter |
utm_medium |
The marketing medium | cpc, email, social |
utm_campaign |
The campaign name | launch-2025, black-friday |
referrer_url |
The full URL the visitor came from | https://producthunt.com/posts/... |
If no utm_source is provided, the subscriber is attributed to direct.
How UTM parameters work
UTM parameters are query string values you add to your waitlist URL. When a visitor arrives via a tagged link, VOTLI reads the parameters and stores them automatically — no setup required on your end.
Example link
https://yourapp.vot.li/waitlist?utm_source=twitter&utm_medium=social&utm_campaign=launch
When someone clicks this link and signs up, their subscriber record will show:
- Source: twitter
- Medium: social
- Campaign: launch
Standard sources
These sources have dedicated color labels in the dashboard:
| Source value | Label color |
|---|---|
google |
Blue |
twitter |
Sky |
facebook |
Indigo |
linkedin |
Violet |
newsletter |
Amber |
direct |
Emerald (default) |
Any other source value is displayed with a neutral label and is still tracked and filterable.
Referrer URL
The referrer URL is captured automatically from the browser's HTTP Referer header, independently of UTM parameters. It records the full URL of the page the visitor came from — useful when UTM tags are not present.
In the subscriber table, rows with a referrer URL show a clickable link in the expanded detail view (click the chevron on any row to expand it).
Filtering by source
On the subscriber list page, click Breakdown in the Traffic Sources stat block to see a bar chart of your top sources. Clicking a source bar filters the table to show only subscribers from that source.
Exporting tracking data
The CSV export includes all tracking fields:
- Name
