Being new to GTM. My question might be very lame. I have following query in regards to datalayer.push code/method/function If i want to place datalayer.push code/method/function on web pages were should i place the code on the page 1) should it be above GTM code 2) should it be below the GTM code 3) should I place it were I declare/define the datalayer
Also, would like to know if there are rules that need to be followed while placing the datalayer.push code/method/function on the pages Thanks in advance.

Some best practices regarding the dataLayer including defining the initial dataLayer BEFORE the GTM container:
<body>
<script>
dataLayer = [{
'event': 'someEvent',
// other parameters
}]
</script>
<!-- Google Tag Manager -->
...
<!-- End Google Tag Manager -->
and if you want to do a dataLayer.push, then that also should come before the container.
<body>
<script>
dataLayer = [{
'event': 'someEvent',
// other parameters
}]
</script>
<script>
dataLayer.push({
'category': 'clothing',
// other additional parameters
})
</script>
<!-- Google Tag Manager -->
...
<!-- End Google Tag Manager -->
In some cases, you may want to check to see if the data layer object has been defined or not first, before pushing to it:
window['dataLayer'] = window['dataLayer'] || []
dataLayer.push({
'newVar': 'newValue'
})
