## How to Handle Large Discrepancies Between Click Count and Conversion Count

When there is a large difference between the click count and conversion count in heatmaps, or when heatmaps are not displaying correctly, the following causes are possible. First, identify the cause and perform the appropriate settings.

***

## **Case 1: Cross-domain settings are not configured**

When the domain of the page that transitions after clicking a CTA button (for example: action buttons such as purchase or application) is different, **cross-domain settings** are required. If this setting is not configured, the following problems may occur:

Conversions are not measured correctly.

Large discrepancies occur between click count and conversion count in heatmaps.

By configuring cross-domain settings, you can accurately track user behavior across different domains. If you have forgotten to configure this, please check the following:

Verify the domain of the URL that transitions after clicking the CTA button.

Add [Cross-domain settings](/en/faq/data/click-cv-mismatch.md) in the Ptengine admin panel.

## Case 2: Different data counting rules

Conversions are recorded based on [visit count](/en/faq/data/click-cv-mismatch.md). Even if multiple conversions occur during a single visit, the count is only 1.

Additionally, there is approximately a 2-hour time lag before conversions are reflected. Please check again after some time.
