We've got a number of sites in Sitebuilder and are reluctant to switch to SCA, as we've got some concerns around the SEO model. We've got responsive Sitebuilder layouts working in sandbox and would like to include dynamically generated suitescript content in our category and/or item templates. I could do this after page load with jquery fetching data from a restlet which is then written to the page, but don't want to do this, as it's also liable to similar issues with SEO.

I thought that the <%=include('URL')%> tag would allow us to include pre-parsed content from suitescripts in the page, but get error messages saying that this method is not allowed if I try and link this to a suitescript public URL.
