This metric tracks how many upsell events occur on your website and are successfully detected and attributed by GrowthOptix.
What Upsells Quantity Measures.
Upsells Quantity measures how many upsell actions happen, not their monetary value.
Each upsell event increases this count by one, regardless of the amount.
This metric focuses on customer expansion behavior, helping you understand how often existing customers make additional purchases.
How Upsells Quantity Is Measured In GrowthOptix.
Upsells Quantity is measured on-site, using the GrowthOptix Tracking Script.
GrowthOptix records an upsell when:
A user has already completed an initial sale.
An additional purchase event occurs.
The event is classified as an upsell.
The GrowthOptix Tracking Script detects the event.
The event is successfully processed and attributed.
Only upsell events that are clearly identified and captured by the script are counted.
Where To Find This Metric.
You can find Upsells Quantity in:
Marketing Attribution Overview.
Source-level tables.
Campaign-level tables.
Metric Chart View.
Different tables across Marketing Attributtion.
This allows you to analyze upsell behavior by traffic source, campaign, or attribution model.

Upsells Quantity vs Upsells Amount.
It’s important to distinguish between these two metrics:
Upsells Quantity: Number of upsell events.
Upsells Amount: Total monetary value generated from upsells.
A high Upsells Quantity with a low Upsells Amount may indicate low-priced add-ons, while fewer upsells with high value may signal premium upgrades.
Example: How Upsells Quantity Is Calculated.
Imagine the following scenario during a selected period:
20 customers purchase an add-on.
10 customers upgrade their plan.
5 customers purchase an additional product.
GrowthOptix records:
20 upsell events
10 upsell events
5 upsell events
Upsells Quantity = 35
Each completed upsell action is counted once.
Why Upsells Quantity Matters.
Upsells Quantity helps you understand:
How often customers make additional purchases.
The effectiveness of post-purchase offers.
Customer lifetime value expansion behavior.
Which channels generate customers more likely to upsell.
It becomes especially useful when paired with:
Upsells Amount: Revenue impact of upsells.
Sales Quantity: Initial conversion volume.
Revenue: Overall monetization.
Visitors / Sessions: Expansion relative to traffic.
Best Practices.
To ensure accurate Upsells Quantity tracking:
Clearly distinguish upsell events from initial sales.
Ensure upsell events fire correctly on completion.
Avoid duplicate event firing.
Validate upsell tracking after deployment.
Use consistent event naming and classification.
Limitations & Important Notes.
Upsells Quantity depends entirely on event tracking accuracy.
Misclassified events may inflate or reduce counts.
Attribution models affect how upsells are assigned to sources.
This metric reflects actual upsell actions captured on-site, not platform-side reports.
