How do websites display product attributes listed with their meta descriptions in Google SEPRs?

[Troyville]

If you take a look at this SERP for "boys costumes" you can see that Amazon, HalloweenExpress and Target all have attributes listed such as "Products 1-25 of 500" or Kids Legolas _Costume. _

These are getting blended with their meta descriptions.  How are they doing this?  Anyone see any lifts in ranking or CTR by doing this?

Thank you!

I don't know what exactly this is, but you can implement useful snippets of information, like price, rating, reviwe counter with schema.org. I personally haven't got any long time experience with it but it is said to lift CT. This should be true as users searching for items with reviews for example can find clues that here they will find some.

I believe people are getting these types of listings by using Google's Merchant Center for selling their products.

Yes, thank you.  I just dug in a little more.  Here is a good overview: http://blog.crowdint.com/2011/09/27/better-seo-with-rich-snippets-for-e-commerce.html

I have seen this happen on e-commerce sites that don't have meta descriptions on the category pages. Often "Products 1-25" is the first text on the page and google will pull that as part of the meta description.
