Hello all! I have a question about google products starts in search. Back in May 2015 I noticed that they began to disappear, I used to implement them with schema.org then but noticed that all the competitors using data-vocabulary.org had snippets in place. I changed my markup accordingly, but the stars are still missing. Each product page has reviews with dates. I changed the dates a few times. Can be the reason? Or maybe anything else? BTW, according to the Webmaster Console and Google rich snippets preview tool, there are no problems or issues, everything seems to be ok.
