We just built structured content (review) by following the specification from Schema.org. We like our client website stand out with the rating (5 stars) on the search result.
So far this is working on Google. If you search for "hyundai high wycombe" on Google, you will able to see the 5 stars mark-up visual return from the search result. But, this is not working on Bing search engine.
We did check this with the Markup Validator on Bing webmaster tool for this URL http://www.hyundai.co.uk/dealer/platts-high-wycombe. We found everything look alright.
Any idea why the 5 stars for the URL above is not showing on the search result from Bing?
