The correct answer is: “The attribution report.”
Why is this correct, and why are the other options incorrect? In this guide, I’ll explain what attribution reports do, how they help marketers compare conversion data across models, and why this is a common Google Ads Measurement Certification exam question. So no delay. Let’s get started.

The Question
A marketing analyst is analyzing the conversion data of their Search Ads campaign in Google Ads. They want to see how changes to their attribution model might impact conversion reporting. What report will provide them with that information?
A. The conversions report
B. The click analysis report
C. The attribution report
D. The campaigns report
The Correct Answer
✅ C. The attribution report
Why This Is Correct
The Attribution report in Google Ads is designed specifically to help marketers understand how different attribution models (such as last-click, data-driven, linear, or time decay) affect the way conversions are credited to various touchpoints across a user’s journey.
In this case, since the analyst wants to see how changing the attribution model affects conversion reporting, the Attribution report is the only report that allows for model comparison and simulation. Google Ads provides a section within Attribution reports called “Model Comparison”, where users can view how conversions shift depending on which model is applied.
This helps in making informed decisions about campaign optimization, bid strategies, and budget allocation.
Why Other Options Are Incorrect
A. The conversions report
This report shows how many conversions occurred and basic data about them (like source, device, etc.), but does not let you compare attribution models. It’s focused on reporting conversions as counted using the currently selected attribution model.
B. The click analysis report
This report is not a standard report in Google Ads. It may refer to metrics like click-through rate (CTR), click share, or interaction metrics, but it has no relation to attribution modeling.
D. The campaigns report
The campaigns report shows performance at the campaign level (e.g., impressions, clicks, cost, conversions) but again only reflects data based on your currently selected attribution model. It does not allow for attribution model comparisons or simulations.
Comparison Table
Report Type | Attribution Model Comparison | Tracks Conversions | Used for Optimization |
---|---|---|---|
Attribution report | ✅ Yes | ✅ Yes | ✅ Yes |
Conversions report | ❌ No (uses current model only) | ✅ Yes | ✅ Yes |
Click analysis report | ❌ No | ❌ No | ❌ No |
Campaigns report | ❌ No | ✅ Yes (basic) | ✅ Yes |

Where to Find the Attribution Report in Google Ads
- Go to your Google Ads account
- Click on Tools & Settings (wrench icon)
- Under “Measurement,” choose Attribution
- Open the Model Comparison tab
- Select and compare multiple attribution models to see how they shift conversion credit across your campaigns or keywords
Real-Life Example

Alex is a marketing analyst running Search Ads across branded and generic keywords. His manager wants to move away from last-click attribution and test data-driven attribution (DDA).
Alex goes to the Attribution > Model Comparison report. He selects last-click and DDA, and compares how each model assigns credit. He notices that branded terms get less credit under DDA and that upper-funnel terms get more.
Thanks to this report, Alex makes better decisions about budget and bidding strategies.
