Exclude GTM code from AMP

You could use if ( function_exists( 'is_amp_endpoint' ) && is_amp_endpoint() ) { return; } as the first thing within your functions.

This will prevent the JavaScript from being output on AMP pages.

Thank you Sir..Thank you very much..You are always helpful…

Hi @swissspidy,
I have added this code but not working-

/* Google Tag Manager START */
if ( function_exists( 'is_amp_endpoint' ) && is_amp_endpoint() ) {
add_action( 'wp_head','add_gtm_script_part' );
function add_gtm_script_part () { ?>
<script>(function(w,d,s,l,i){w[l]=w[l]||[];w[l].push({'gtm.start':
new Date().getTime(),event:'gtm.js'});var f=d.getElementsByTagName(s)[0],
j=d.createElement(s),dl=l!='dataLayer'?'&l='+l:'';j.async=true;j.src=
'https://www.googletagmanager.com/gtm.js?id='+i+dl;f.parentNode.insertBefore(j,f);
})(window,document,'script','dataLayer','GTM-543DQCK');</script>
<?php }

add_action( 'astra_body_top','add_gtm_noscript_part' );
function add_gtm_noscript_part () { ?>
<noscript><iframe src="https://www.googletagmanager.com/ns.html?id=GTM-543DQCK"
height="0" width="0" style="display:none;visibility:hidden"></iframe></noscript>
<?php }
} else {  }
/* Google Tag Manager END */

Can you please check?

You have to add this code within your functions. Not outside. Here’s an example:

add_action( 'wp_head','add_gtm_script_part' );

function add_gtm_script_part () {
if ( function_exists( 'is_amp_endpoint' ) && is_amp_endpoint() ) { return; }
?>
<script>(function(w,d,s,l,i){w[l]=w[l]||[];w[l].push({'gtm.start':
new Date().getTime(),event:'gtm.js'});var f=d.getElementsByTagName(s)[0],
j=d.createElement(s),dl=l!='dataLayer'?'&l='+l:'';j.async=true;j.src=
'https://www.googletagmanager.com/gtm.js?id='+i+dl;f.parentNode.insertBefore(j,f);
})(window,document,'script','dataLayer','GTM-543DQCK');</script>
<?php }
