But installing Google Tag Manager in Blogger Blog is a little tricky as it is not exactly same as installing it in WordPress or any other website, you have to make a very small change in the GTM Container Snippet then only it will work.
So if you already know how to Install GTM in WordPress and in other places, you facing problem only with Blogger, then do this -
In the GTM Container Snippet (in <head> Script) find dl=l!='dataLayer'?'&l='+l:'';, change the ampersand (&) to its HTML encoded version (&)
So, the string
dl=l!='dataLayer'?'&l='+l:'';
will look like this
dl=l!='dataLayer'?'&l='+l:'';
Save the changes and you are done.
