# Heatmap Not Displaying

If your heatmap is not displaying or experiencing display issues, the possible causes and solutions are as follows.

**No Access Data** **Solution**: Verify that data has been accumulated for the target URL and confirm that the tracking code is installed correctly. Data accumulation may take 30 minutes to 1 hour.

**Page Selection Issue** **Solution**: Select the correct page type and verify the heatmap for each parameter.

**Element Changes Due to Page Updates** **Solution**: It is recommended to save the heatmap before making updates.

**Impact of URL Standardization Rules** **Solution**: Use a URL that follows the standardization rules or disable the standardization rules.

**Impact of Page Redirects** **Solution**: You need to disable redirects.

**Network or Browser Issues** **Solution**: Try switching your network environment or using a recommended browser. Browser updates and temporary disabling of extensions can also be effective.

**Free Plan Limitations** **Incorrect URL Registration**: The Free plan only allows heatmaps for 1 URL. You need to set the correct URL.

**Webview Heatmap Checklist** **Tag Installation Verification**: Verify that the Ptengine tag is installed correctly.
