Understanding Discrepancies Between Google Analytics 4 and Webgains

Businesses often encounter discrepancies between metrics reported in Google Analytics 4 (GA4) and affiliate platforms like Webgains. These inconsistencies can make it difficult to accurately assess the true performance of various marketing channels, especially when affiliate-driven conversions appear lower in GA4. For companies relying on performance metrics to allocate budgets, refine strategies, or evaluate partnerships, understanding and addressing these discrepancies can unlock greater clarity and confidence in decision-making.

The following sections outline key factors causing these differences and provide actionable solutions to enhance data consistency. By understanding the root causes, businesses can better interpret data from each platform and make informed decisions.

Key Issues Leading to Data Discrepancies

Attribution Models: Last Click vs. Multi-Touch

GA4 and affiliate platforms like Webgains use distinct methods to assign credit for conversions, often leading to data discrepancies. GA4’s multi-touch model offers a comprehensive view by distributing credit across multiple touchpoints, while Webgains credits the final click before conversion.

For businesses, this means that GA4 may show lower conversion rates for affiliate channels, undervaluing their impact. Adjusting GA4’s attribution model to match Webgains' last-click approach can help reconcile these differences, giving a clearer picture of the effectiveness of affiliate channels and avoiding misguided cuts to affiliate budgets based on incomplete data.

Event-Based vs. Conversion-Focused Tracking

GA4’s event-based model logs each interaction, such as clicks and page views, as a separate event. Affiliate platforms, however, focus primarily on the final conversion point, like a click leading directly to a sale.

For businesses focused on the overall journey (like brand awareness and engagement before purchase), GA4 offers detailed behavioral insights that can shape top-of-funnel strategies. However, if conversion performance is the primary goal, relying more on Webgains' conversion-focused data may better align with direct ROI tracking, highlighting where affiliates contribute directly to sales.

Privacy Regulations and Cookie-Based Tracking

Strict privacy laws impact GA4’s cookie-based tracking, which limits visibility into certain user interactions. Webgains, however, often uses cookie-free tracking links, allowing for more complete tracking in restricted environments.

For businesses, this gap emphasizes the need to diversify tracking methods and possibly consider server-side tracking, especially for markets with strict privacy regulations. Understanding these privacy-based discrepancies ensures businesses don’t underreport traffic and conversions, leading to more accurate channel evaluations and optimized budget allocations across regions.

Real-Time Data Reporting vs. Data Lag

GA4’s data lag can be up to 24 hours, while Webgains provides near-real-time tracking. This timing difference can cause temporary discrepancies, especially during promotions or high-traffic periods.

For businesses running time-sensitive campaigns, relying on real-time affiliate data can ensure quick, accurate adjustments. Recognizing these timing differences helps avoid premature decisions based on delayed data and optimizes in-campaign adjustments.

Ad-Blockers and Script Limitations

Since GA4’s JavaScript-based tracking can be blocked by ad-blockers, some user interactions go unrecorded. Webgains’ link-based tracking bypasses most ad-blockers, offering a more comprehensive view of user behavior.

Businesses catering to privacy-conscious audiences can benefit by leaning on affiliate data, which may capture a more complete picture of traffic and engagement that GA4 misses. Understanding this difference can provide a more realistic view of affiliate-driven performance and help in choosing tracking solutions that align with their audience’s preferences.

Conversion Definitions: Varying Criteria

GA4 allows custom conversions, like page views and cart additions, while Webgains counts only final conversions, like completed transactions.

These definitional differences help companies choose the right platform to evaluate performance based on their specific goals. For brand engagement, GA4’s custom events may be more relevant, whereas for direct conversions, Webgains' focused tracking offers more precise data.

Solutions to Address Discrepancies

The above differences create challenges, but implementing the right solutions can help businesses align data across both platforms, maximizing insights and accuracy:

• Adjust Attribution Settings: Matching GA4’s attribution model with Webgains’ last-click approach can bring affiliate performance data into better alignment, avoiding undervaluing affiliate channels and enabling clearer decision-making.

• Standardize UTM Parameters: Consistent UTM tracking across platforms minimizes misattribution and makes data comparison smoother, enhancing channel evaluations.

• Conduct Regular Data Audits: Routine data checks with tools like Google Data Studio help detect patterns or anomalies, improving cross-platform clarity and catching issues early.

• Implement Server-Side Tracking: Reducing reliance on cookies addresses privacy law impacts and enhances data accuracy, particularly in regions with stringent privacy regulations.

• Use Affiliate Platform Data as Primary Source: Since affiliate platforms are built specifically to track affiliate-driven traffic, relying on their data for affiliate reporting can provide a more accurate picture for evaluating affiliate partnerships.

• Consult with Affiliate Tracking Experts: For persistent discrepancies, expert input can help optimize tracking configurations and uncover hidden issues, ensuring reliable data.

Understanding discrepancies from a different perspective

Imagine your business as a retail shop with multiple entrances, each representing a different marketing channel guiding customers into your store. Let’s explore how these discrepancies play out in this analogy:

1. Attribution Models: Credit for Every Entrance

   Think of each entrance as a unique path to the sale. GA4 acknowledges all doors a customer enters through before purchasing, distributing credit among them. Webgains, however, credits only the final entrance. This approach leads GA4 to record lower affiliate-driven conversions, as it credits multiple channels for a single sale.

2. Counting Clicks: Tracking Engagement Levels

   Every affiliate click represents a customer opening a door to the shop. Webgains logs every door opened, even if they don’t enter fully. GA4, however, only logs actual entries, leading to higher click counts in Webgains and potential confusion.

3. Privacy Settings: “Name Tag” Limitations

   Cookies serve as “name tags” for returning visitors, but privacy regulations often remove these. GA4 might not recognize returning customers due to cookie restrictions, while Webgains’ link-based tracking allows more comprehensive recognition, especially in regions with strict privacy laws.

4. Reporting Delays: Real-Time vs. Delayed Updates

   GA4 operates with a lag, like a shop that updates visitor counts later. Webgains, with near real-time tracking, reflects performance immediately, especially useful during promotions or events.

5. Effects of Ad-Blockers: Untracked Customers

   Ad-blockers prevent some visitors from being logged in GA4, while Webgains, with link-based tracking, bypasses blockers to record more interactions.

6. Definitions of Key Actions: Conversion Variety

   GA4 treats browsing or cart additions as conversion-worthy actions, while Webgains might log only checkouts. This results in differing conversion counts and can complicate direct comparisons.

Conclusion

Understanding and addressing the causes of discrepancies between GA4 and affiliate platforms like Webgains offers significant value. By aligning tracking methods, configuring attribution settings, and performing routine audits, businesses can achieve greater clarity in their data and confidence in their strategic decisions.

GA4 provides a detailed, multi-touch view, while affiliate platforms excel at last-click conversions. Together, these tools allow for a holistic view of user behavior across the entire journey, from initial touchpoints to final purchase.

Aligning data across platforms not only improves reporting accuracy but also optimizes marketing investments. This integrated approach helps businesses leverage each platform’s unique insights, driving better budgeting, strategic planning, and, ultimately, improved marketing outcomes across channels.
