    Hello,

    I just want to make sure if this kind of behavior is normal, or if I should try to figure out why it happens:

    I put the code:
    <?php if ( function_exists( 'gtm4wp_the_gtm_tag' ) ) { gtm4wp_the_gtm_tag(); } ?>
    right after <body> in header.php

    When inspecting the DOM I can see that there are 2 blocks of code inserted by the plugin, one of them is all in the header (NO.#1), the other one spans across the <head> and <body> – it starts before </head> and ends after <body> (NO.#2).

    Here’s an excerpt for (NO.#1):

    <!-- Google Tag Manager for WordPress by DuracellTomi - http://duracelltomi.com -->

<em>a facebook scrips..
tawk.to script..</em>

<script type="text/javascript">
	var gtm4wp_datalayer_name = "dataLayer";
	var dataLayer = dataLayer || []
</script>
<!-- End Google Tag Manager for WordPress by DuracellTomi -->

    Here’s an excerpt for (NO.#2):

    ... some <head> code here...
<em><!-- Google Tag Manager for WordPress by DuracellTomi --></em>
<script type="text/javascript">
	dataLayer.push({"pagePostType":"page","pagePostType2":"single-page","pagePostAuthor":"MyWebsite"});
</script>
    <strong></head></strong>
    <strong><body></strong>
<noscript><iframe src="//www.googletagmanager.com/ns.html?id=GTM-MyID"
height="0" width="0" style="display:none;visibility:hidden"></iframe></noscript>
<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=
'//www.googletagmanager.com/gtm.js?id='+i+dl;f.parentNode.insertBefore(j,f);
})(window,document,'script','dataLayer','GTM-MyID');</script>
<em><!-- End Google Tag Manager --></em>
... some <body> code here...

    I have 3 questions:

    1) Is it OK that I have any code related to the plugin in the <head> where I only called the pulgin’s function after body?

    2) Is it OK that I have this kind of code like shown in (NO.#2) where part of the block (according to your comments) is in the <head> and the rest is in the <body>?

    3) Is it natural that the comment block of code the plugin inserts surrounds other elements/scripts loaded in the page? (NO.#1)?

    Thank you!!

    Hi,

    1) yes, that is normal, in the <head> section I define the so called data layer variables that needs to be accessible while your tags firing on “All pages” trigger.

    2) Yes, the code at the beginning of the <body> loads your published GTM container and starts to fire your tags on “All pages”

    3) No, that is an odd behavior and it might be caused by some cache plugins
