Navigating Data Discrepancies: A Deep Dive into Attribution Models and Conversion Tracking

Understanding data discrepancies between platforms like Google Ads, Google Analytics, and Shopify is essential for accurately measuring your digital marketing performance.

This blog post will guide you through the key factors contributing to data discrepancies, including attribution models and conversion windows, and provide actionable strategies for navigating these challenges effectively.

What Are Data Discrepancies?

Data discrepancies occur when different platforms report varying metrics for the same data points. Each platform—Google Ads, Google Analytics, and Shopify—tracks and reports data differently, leading to inconsistencies. Here’s a closer look:

• Google AdsTracks clicks and conversions directly attributed to its ads.

• Google AnalyticsAttributes conversions based on various models and encompasses traffic from multiple sources.

• ShopifyReports based on its tracking mechanisms, which can be affected by external factors such as payment gateways.

  
  

How Attribution Models Contribute to Discrepancies

Attribution models are crucial in determining how credit for conversions is assigned throughout the customer journey. Common attribution models include:

• Last Click: Assigns all credit to the last touchpoint before conversion.

• First Click: Gives all credit to the first touchpoint.

• Linear: Distributes credit evenly across all touchpoints.

• Position-Based: Allocates more credit to the first and last touchpoints, with less to the middle ones.

  
  

Different platforms may use different attribution models, leading to discrepancies in reported conversion data.

The Role of Conversion Windows

Conversion windows are timeframes during which conversion can be attributed to a specific touchpoint. For example, a 30-day conversion window means that if a user clicks on an ad and converts within 30 days, the conversion is attributed to that ad. Variations in conversion windows can result in differences in reported conversion numbers.

Real-Life Example: Attribution Discrepancies

Consider a scenario where a user clicks on a Google Ad, visits your site, but doesn’t purchase. They later return via an organic search and complete the purchase. Here’s how different platforms might track this:

• Google Ads: Credits the conversion to the paid search.

• Google Analytics: Might attribute the conversion to the organic search if it was the last touchpoint.

  
  

This can cause discrepancies where Google Ads reports the conversion as paid, while Google Analytics shows it as organic.

How to Navigate Data Discrepancies

1. Compare Attribution Models Both Google Ads and Google Analytics offer tools for comparing different attribution models. This helps in understanding how conversions are credited under various models.

How to Access Attribution Model Comparisons:

• Google Ads: Go to "Tools and Settings," then "Attribution," to compare data across models.

• Google Analytics: Navigate to "Acquisition," then "Attribution," to explore different models.

  
  

2. Analyze Conversion PathsUse Google Analytics to examine top conversion paths and see how customers interact with your site across various channels.

3. Review and Adjust Conversion WindowsEnsure consistency in conversion tracking settings by aligning conversion windows across Google Ads and Google Analytics.

Conclusion and Next Steps

Understanding and addressing data discrepancies is vital for optimizing your digital marketing efforts. To ensure accurate measurement and improve performance, follow these steps:

• Compare Attribution Models: Use tools in Google Ads and Google Analytics to evaluate how different models impact reported data.

• Analyze Conversion Paths: Investigate customer interactions across multiple channels.
