# How to Check if Tags are Firing Correctly By verifying in advance that measurement tags are correctly installed, you can prevent data measurement gaps and malfunctions, and enable accurate site analysis. Additionally, you can detect configuration errors such as duplicate tag installations early on. ## Common Use Cases During initial setup immediately after installing Ptengine measurement tags on your website When you want to verify that data is being measured correctly When measurement issues are suspected due to duplicate tag installations, etc. ## Method 1. Verification in the Admin Dashboard Open **\[Basic Settings and Tag Acquisition]** > **\[Analytics Code]** from the gear icon in the top right of the admin dashboard. Click the **\[Check Tag Installation Status]** button. You can verify whether tags are installed by entering the URL of the page you want to check. ## Method 2. Verification in Developer Tools More detailed verification is possible using your browser's Developer Tools (Inspection mode). Access the page where the tag is installed, right-click on the site, select **\[Inspect]**, and open the Developer Tools. Open the **\[Network]** tab and type "`ptengine`" in the search box. When you scroll or click on the page, a package called "`collect`" will appear. If this is displayed, measurement is working correctly. Next, refresh (reload) the page in your browser. Verify that a package in the format "`××××××××.js`" (tag ID) is displayed. Verify that the package's ID matches your tag ID issued in the Ptengine admin dashboard. If the IDs don't match or multiple IDs are displayed, tags from another account or project may have been incorrectly installed. Since duplicate tags can cause measurement issues, remove the incorrect tags from your site and keep only the tag with the correct ID. --- # Agent Instructions: Querying This Documentation If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.
