At a Glance
- Use SubIDs iGaming tracking to carry campaign, audience, creative, and placement context into affiliate reports.
- Define what sub1, sub2, and sub3 mean before launching traffic.
- Keep naming conventions stable across ad platforms, trackers, CRM, and finance exports.
- Test encoding, truncation, missing values, and privacy boundaries before scaling.
Use SubIDs iGaming tracking to understand where affiliate traffic came from and which campaign components were associated with a click or conversion. SubIDs are usually short parameters attached to a tracking link. They do not create attribution by themselves; they make an existing click relationship more useful for reporting.

What SubIDs are and why use SubIDs iGaming tracking
Key Definition: A SubID is a partner-defined tracking parameter that carries source, campaign, audience, placement, or creative context through an affiliate click and into downstream reporting.
A common structure is sub1 for campaign, sub2 for audience or ad set, and sub3 for creative. The exact names are not universal. What matters is that the operator and partner agree the meaning, allowed characters, and destination fields.
| Field | Example meaning | Example value | Reporting use |
|---|---|---|---|
| sub1 | Campaign | summer-rush | Compare campaign groups |
| sub2 | Audience or ad set | sports-25-34 | Compare targeting structures |
| sub3 | Creative or placement | video-01 | Find creative or placement patterns |
Design a consistent SubID convention
Write the convention in one sentence and use it everywhere. For example: “sub1 is campaign, sub2 is audience, sub3 is creative.” Use lowercase values, hyphens or underscores, and a controlled vocabulary. Avoid personal data, free-text notes, and values that reveal sensitive player information.
A clean illustrative link may look like:
https://example.com/offer?sub1=summer-rush&sub2=sports-25-34&sub3=video-01
The example is fictional. Replace it with the operator’s approved tracking domain and parameter contract.
Pass SubIDs through the full flow
- Generate the affiliate link with the agreed values.
- Click the link and confirm the landing page receives the parameters.
- Store the values with the click ID in the tracker.
- Pass the click ID and approved SubIDs into the player or conversion record.
- Return the values or click ID in the postback where the contract allows it.
- Expose them in CRM, partner, and finance reports with the original timestamp.
Operator pro-tip: keep a campaign dictionary with examples and owners. A naming convention without ownership usually drifts within a few launches.
SubID quality checks
| Check | Question | Failure response |
|---|---|---|
| Presence | Are values present on every intended link? | Fix link generation or reject incomplete tests |
| Encoding | Do spaces and special characters survive? | Use allowed characters and encode consistently |
| Length | Does any system truncate the value? | Set limits and alert before launch |
| Mapping | Do reports show the same meaning? | Correct field mapping and version the contract |
| Privacy | Could the value identify a person? | Remove it and use an approved aggregate label |
Illustrative reporting example
Suppose a campaign report shows sub1 values by campaign, sub2 values by audience, and sub3 values by creative. An operator can compare approved conversions and later lifecycle outcomes by those groups without rebuilding the click path from memory. The example demonstrates structure, not a benchmark or promised performance.
Edge cases and failure scenarios
One redirect may retain sub1 but discard sub2 and sub3. A partner may reuse the same creative value across campaigns. An ad platform may replace spaces with encoded characters. A missing SubID can be mistaken for organic traffic. Keep the original click record, label missing values explicitly, and alert on sudden shifts in value distribution.
Conclusion
To use SubIDs iGaming tracking well, treat parameters as a small data contract rather than decoration on a URL. Stable definitions, controlled values, end-to-end tests, and privacy checks make affiliate reports easier to trust and connect to CRM decisions.
