Duplicate customer records create significant attribution errors when merging Google Ads and NetSuite datasets. Same customers exist multiple times with different IDs, fragmenting Google Ads attribution and undermining accurate marketing ROI analysis.
Here’s how systematic deduplication creates clean, consolidated customer data for reliable marketing attribution.
Advanced matching logic identifies and consolidates duplicates
Coefficient provides systematic deduplication solutions through comprehensive data integration. While duplicate records fragment attribution across multiple NetSuite entries, automated matching logic consolidates customer data for accurate Google Ads ROI tracking.
How to make it work
Step 1. Import comprehensive customer data for duplicate identification.
Use Records & Lists to pull all NetSuite Customer records with key identifying fields including email, company name, phone, and address. This provides the data foundation for systematic duplicate detection.
Step 2. Create advanced matching formulas.
Build VLOOKUP, XLOOKUP, and fuzzy matching techniques to identify potential duplicates based on multiple criteria rather than exact matches. Account for email variations, company name abbreviations, and formatting differences.
Step 3. Correlate Google Ads conversions with master customer records.
Import Google Ads conversion data with customer identifiers, then use Coefficient’s data to create master customer records that consolidate multiple NetSuite entries for accurate attribution.
Step 4. Set up automated duplicate flagging.
Schedule regular data refreshes that automatically identify new duplicate records as they’re created in NetSuite. This maintains clean attribution over time without manual monitoring.
Step 5. Aggregate revenue from duplicate records.
Consolidate transaction amounts from duplicate NetSuite customer records to calculate accurate customer lifetime value for Google Ads ROI analysis. Use SUM formulas to combine revenue across duplicate entries.
Step 6. Ensure consolidated attribution accuracy.
Make sure Google Ads campaign attribution reflects consolidated customer value rather than being split across duplicate records. This provides accurate marketing spend analysis and customer acquisition costs.
