So, I am looking to add a tag that I want to use for A/B testing, however we don't have a page-type URL structure. Fortunately the tool can recognise page type if I pass it by Javascript.<script type=text/javascript>window.isProductPage = true;</script>I have been told to use the above, I have created the script in Google Tag Manager (GTM), however I now need to know how to make this run on those pages in GTM.I have looked through the code and there are div class that are unique to each page, can I use this as an indication of page type?
Using Google Tag Manager to define the page type
