This tool allows you to quickly check if a website has Google Tag Manager (GTM) installed and provides the GTM ID if detected. Simply enter the website URL in the form, and the tool will analyze the site to identify the presence of GTM. It's fast, easy to use, perfect for marketers, developers, or anyone working with website analytics who want to quickly just check if the code is there or not, and if it is the right ID.
