FAQPage, answering real questions about this lab
The one specimen whose subject is genuinely real: this site. Every question and answer below is true.
This specimen is different from the others. There is no invented subject here. The questions are ones this site actually gets asked, and the answers are true, which makes it the cleanest test in the collection: if FAQ markup fails here, it is not failing because the content was thin.
Is anything on this site real?
The lab is. The subjects of most specimens are not. Every page that describes a fictional business, person, product or event says so in its opening line and in its own markup, in a disambiguatingDescription property that ships with the page rather than sitting in prose a parser will never read.
Why not just test on a real site?
Because a real site brings its own authority, its own links and its own history, and there is no way to separate what the markup did from what those did. This domain has effectively none of them, which is the only reason the question can be asked cleanly here.
Does schema markup improve rankings?
That is the question, and this site does not yet have an answer. It has a method, a control, and a set of specimens waiting to be measured. Anything stated before the measurements exist would be an opinion wearing a lab coat.
Why are some properties missing from the markup?
Rating and review properties are removed before output unless a specimen names a real, checkable source for them. Inventing them would mean asserting other people’s judgement as fact to every parser that reads the page, and no on-page disclaimer reaches a parser. Where that happens the page says what was withheld and shows the authored version alongside.
