Google Tag Manager allows you to avoid tagging scripts as described below, although this is limited to a certain category of scripts – scripts that are not positional/do not define a position. It, therefore, does not handle embed scripts such as those related to advertising banners, youtube video widgets, facebook like buttons etc.

This method has the advantage of being quite fast but with the limit of working only for scripts that don’t require a specific position. Google Tag Manager is therefore not effective for all scripts that display a specific element in a specific position of the page (such as the Facebook Like button).
