Re: Site Structured Data module for X-Cart Classic
You have to have the actual FAQs visible on the page for the customer not just the markup. Google may not even consider it if there is nothing that customers see or if the info is different.
If this is going to be all the same on all categories repeating it on every category page is really not the way to go. Just create FAQ static page and you can add the markup to it as well.
If every category will have different FAQ block you can still use static pages but you will have to reference them conditionally in the subcategories template and this can get really messy if there are more than say 2-3 FAQ pages. In this case it is really better to have a simple custom module to allow you to add FAQs on per category basis in admin and this will also output all the info.
