Google Tagmanager has very specific instructions for including their tags in a website.
Currently adding it to the webstatistics box does not fulfil the requirements which are:
Place the <script> code snippet in the <head> of your web page's HTML output,
preferably as close to the opening <head> tag as possible, but below any dataLayer declarations.
Place the <noscript> code snippet immediately after the <body> tag in your HTML output.
The current option inserts included js at the end of the page.
Thinking aloud
Should we be thinking about a "script in head" box and "insert at beginning of body" option for the site controlpanel?
