Gtag.js or Google Tag Manager?
If your website is already using Google Tag Manager, then gtag.js is not necessary and continue to use GTM. Since GTM inherently combines event data from Google Analytics and Google Adwords, it’s best to keep it running if it’s already in place.

r/GoogleTagManager on Reddit: Do I replace gtag code with GTM?
July 22, 2024 -

Hey all,

I am new to this and I couldn't find any relevant resource to help me sort this. Therefore this question. I have a client with a service based web to collect leads and to sell his services. I found a gtag in the web's sourcecode linked to old UA to which he has no access to. So I decided to set up a GTMfrom scratch.

DO I replace the gtag code with the new GTM or is it ok to have them both there? Logically, I'd replace it but I just want to make sure.

Thanks for any advice!

September 27, 2023 - The first code snippet will be inserted just as high as possible before the closing tag </head>. Within the same document, we look for the opening tag of the <body> and insert the second code fragment right after it. Once the code has been inserted, we save the document and update the file on our FTP server (creating a backup copy to be able to revert changes if there are any errors). NOTE: This will be the single manual gearbox that we should do about the source code. Once the GTM code is installed in your header.php file, we can check if it works correctly with the help of the Google Chrome Tag Assistant extension.

A warning message recently appeared across the top of our GA4 instance:

“Your Google Tag code isn’t configured correctly, which may soon prevent your property from measuring automatic events. To fix this, place your Google Tag configuration code in the correct location on all pages that measure events.”

We don’t know what is causing this, as there have been no recent changes to our code or Google tag.

Has anyone else experienced this or know what the issue may be?
