Tracking gaps

People are scanning or clicking a OmniLab Smart Link, but the numbers in analytics do not match what you expected. This guide walks through the most common reasons and how to fix each one.

Before anything else, set the Start Date and End Date on the link's analytics page, then click Run so the view includes your test or launch period.

Symptom

Typical signs of a tracking gap:

• the OmniLab Smart Link works, but analytics still looks empty
• scan volume seems lower than expected
• one variant is not showing the traffic you expected
• UTM or referrer breakdowns look incomplete

Likely causes

Quick diagnostic checklist

Work through this in order:

1. Open the correct OmniLab Smart Link.
2. Choose a Start Date and End Date that definitely include the expected traffic.
3. Click Run.
4. Test the OmniLab Smart Link again with the real link or QR code.
5. If variants are involved, confirm the link includes the correct ?v= value.
6. Compare the scan count, the scans-over-time chart, and Scans by Variant together.

What partial data can still mean

A tracking gap does not always mean the OmniLab Smart Link failed. For example:

• scans can still be counted even when referrer data is missing
• the main OmniLab Smart Link can show traffic even when one variant was never actually used
• channel attribution can differ from referrer data, because the UTM source and the referrer are separate signals

How to reduce future gaps

• test the exact final QR file before launch
• make sure teams distribute the OmniLab Smart Link, not the raw destination
• use variants consistently for placements that need separate reporting
• agree on a stable UTM naming scheme before launch
• run one final QA pass after printing and before broad distribution
