Verifying hreview reviews

[CenturionSigns]

Hi all, I'm trying to get all the microformats done for reviews on a few sites, and would like clarification for aggregate reviews. Specifically, if I create an aggregate reviews page and put that a product or company has a 9 out of 10 rating, with 15 reviews (counts) am i correct in thinking that I then need to make sure that there are indeed 15 individual reviews on the same page, each listing their own score (votes) to ensure that the figures for the average come out right?

Hello,

To get the desired results you must choose which format you can use easily with your code. As Google support various formats for rich snippets like Microformats, RDFa & Microdata.

Here's Example Goes of Microdata:

Blast 'Em Up—Game Review

Rating:
         88 out of
         100

based on
   35 reviews.

Use this tool to verify your code by entering it in HTML Tab, either rich snippets are working or not.

You should use any star rating script (10 stars or 5 stars) and on rating a comment box appear where visitor / user can put his/her review.

You can find more about such formats on Schema.org
