By connecting offline transaction data to digital advertising exposure, JamLoop helps advertisers better understand campaign performance beyond online-only activity.
How It Works
1. Upload Offline Conversion Data
Advertisers provide offline sales or CRM data to Clean Room in a secure format.
Common examples include:
In-store purchase records
Loyalty or membership transactions
Lead or CRM events
Call center sales
Recommended fields include:
Transaction ID
Transaction timestamp
Revenue or purchase amount
Customer identifiers such as:
Email address
First and last name
Mailing address
The more complete the customer data, the higher the likelihood of successful matching.
2. Convert Offline Transactions into Digital Events
JamLoop works with trusted identity resolution partners to translate offline transaction data into digital identifiers such as:
Household IDs
IP-based identifiers
This process allows offline sales to be represented as digital conversion events that can be measured against advertising exposure.
3. Measure Advertising Impact
Once converted into digital events, offline conversions are processed through JamLoop’s attribution system and matched against campaign exposure data.
This enables advertisers to evaluate:
Offline conversions
Revenue and ROAS
Campaign effectiveness
Cross-channel performance trends
Data Formatting Best Practices
To improve attribution quality and reporting accuracy, follow these best practices when preparing offline conversion files.
Use One Row Per Transaction
Each uploaded row should represent a single completed transaction.
Do not upload:
Separate rows for individual products within the same purchase
Separate tax or fee rows
Separate promotional or discount rows
Instead, aggregate all related line items into a single transaction record that includes:
One transaction ID
One total purchase amount
One timestamp
One set of customer identifiers
Include Strong Customer Identifiers
Providing multiple customer identifiers improves match quality.
Recommended identifiers include:
Email address
Full name
Postal address
Include Accurate Timestamps
Transaction timestamps should reflect the actual time of purchase whenever possible.
Consistent timestamp formatting helps improve attribution accuracy and reporting consistency.
Processing Timeline & Expectations
Offline conversion files are processed twice per month:
The 1st
The 15th
Customers should upload files at least 1-2 days before these processing dates.
After submission:
Files are sent to JamLoop's identity resolution partner for matching
Matched records are typically returned within 48 hours
Results are then incorporated into JamLoop's standard attribution processing workflow
In most cases, customers should expect offline attribution results to begin appearing within a few days after a scheduled processing date.
Reporting & Insights
Offline Sales Attribution reporting is available within the JamLoop platform and can be integrated into external reporting or BI environments.
Available metrics may include:
Offline conversions
Revenue attribution
Return on ad spend (ROAS)

These insights can help advertisers optimize media strategy, budget allocation, and overall campaign performance.
