Does Schema.org markup create a conflict with Power Reviews' standard microformat markup for e-commerce product pages?

[BrianCC]

Does anyone have experience implementing Schema.org markup on e-commerce websites that are already using Power Reviews (now Bazaar)? In Google's documentation they say that it's generally not a good idea to use two types of semantic markup for the same item (reviews in this case), but I wouldn't think that there would be a problem marking up other items on the page with Schema such as price, stock status, etc...

Anyone care to provide some insight?

Also in a related topic, have you all noticed that Google has really dialed back the frequency in which they display rich snippets for product searches? A few weeks ago the site that I'm referring to had hundreds of products that were displaying snippets, now it seems that only about 10% (roughly) of them are still showing.

Thanks everybody.

You can use the tool in Webmaster tools ( it's new), that will show you the markup on the page. I haven't noticed that the power reviews interfere with the proper structure of product schema.org on my clients.

The tool will show you the mark up and the results.

Thanks for the response.

The rich snippet testing tool has actually been available for a long time, but they've recently made improvements and created a menu category for it (it was previously in the labs/beta section). However, the tool doesn't actually predict the snippets you get in search results, it just verifies the semantic markup and shows an example of what your snippet might look like. At least that's been my experience with it, and I've heard the same from other people around the industry.

Ideally Power Reviews/Bazaar should just update their markup to Schema.org format. Since that's the preferred format agreed upon by the powers that be, I don't understand why they wouldn't, unless their framework is just extremely rigid.

I appreciate your feedback about your client sites running PR. If I understand the (limited) documentation correctly, this shouldn't be a problem unless I was marking up the exact same data with two different formats. Just wanted to see if anyone else had direct experience. So thanks

I actually meant the new one- not the option that was in Labs. You can access it through:

Optimization>structured data , in the case of the domain I was referring to ( large ecommerce site). It does show the data and the URL that it is on.
