How do I add "structured data" (microdata or rich snippets) to my website's pages?
My website barely seems to register in Google searches, even though I've done just about everything Google recommends in its "SEO" guidelines. According to the Google Webmaster Tools, however, website does not include any "structured data," which I gather can be added by inserting "microdata" vocabulary expressions into the HTML code for each page. But there is no provision for doing anything like this in the SiteBuilder wizard, and as I have already discovered, if I do this manually from the FileManager in cpanel, the HTML code will be overwritten if I ever again use the SiteBuilder wizard (which is very convenient for a neophyte like me to edit my site). Any suggestions for the best way to proceed?
