Google Tag Manager Troubleshooting
Google Tag Manager (GTM) is a powerful tool, but like any platform, it can sometimes present challenges. If you're having trouble installing the Marker.io script via GTM, here's a troubleshooting guide to help you:
Basic Checks
Ensure that you've pasted the correct marker.io script in GTM.
Confirm that the GTM container code has been correctly installed on every page of your website. This is typically found in the
<head>section of your site.
Use GTM Preview Mode
GTM has a 'Preview' mode that allows you to see what tags are firing on a page.
Click on "Preview" in GTM.
Navigate to your website.
Check the GTM debug pane for tag firing information.
Tag Configuration
Make sure that the marker.io tag is set to fire on all pages, or on the specific pages where you want it to load.
Confirm that no other tags are causing conflicts or preventing the marker.io script from executing.
Check Trigger Settings
If you've set specific triggers for the script, double-check them to ensure they're configured correctly.
Ensure the triggers are not too restrictive, preventing the tag from firing.
Cache & Browsers
Clear your browser's cache. Sometimes, cached versions of a site can prevent new tags from executing.
Try accessing your site in an Incognito/Private window. This can bypass certain caching and cookie issues.
Test on different browsers. Sometimes, browser-specific settings or extensions can interfere with script execution.
Check for JavaScript Errors
Using browser developer tools:
Right-click on your webpage, select 'Inspect' or 'Inspect Element'.
Go to the 'Console' tab.
Look for any red errors. JavaScript errors on a page can prevent other scripts (like marker.io's) from running correctly.
Verify the Script's Source
Ensure you are using the latest version of the marker.io script. Sometimes, older versions of scripts can be incompatible with newer web technologies or platforms.
Website Platform Specifics
Some website platforms or content management systems might have specific settings or configurations that can prevent scripts from running. Check any documentation or forums related to your specific platform and GTM.
Check Other GTM Settings
Review any 'blocking rules' or 'exceptions' in GTM that might prevent the script from firing.
Look into the sequence of tag firing. The order in which tags fire can sometimes influence whether they execute correctly.
