I’d like to do schema markup for my wordpress blog in Google Tag Manager. I’ve integrated the variables for Image url and Date Published into my JSON-LD GTM Tag, but I get an error in the Google Structured Data Testing Tool saying:
url – false (The value provided for image.url must be a valid URL.)
datePublished – false (Cannot understand the value false as a date/time. Learn more about date/time formats.)
Can you please help me to find out what do I do wrong?
It looks like your meta tags don't exist or are not properly populated in your blog post pages. Please check and confirm if they are there in the first place so that Google Tag Manager can then extract the values correctly.
