Thousands of Web Pages Disappered from Google Index

[suredone]

The site is  - http://shop.riversideexports.com

We checked webmaster tools, nothing strange. Then we manually resubmitted using webmaster tools about a month ago. Now only seeing about 15 pages indexed. The rest of the sites on our network are heavily indexed and ranking really well. BUT the sites that are using a sub domain are not.

Could this be a sub domain issue? If so, how? If not, what is causing this?

Please advise.

UPDATE:

What we can also share is that the site was cleared twice in it's lifetime - all pages deleted and re-generated. The first two times we had full indexing - now this site hovers at 15 results in the index. We have many other sites in the network that have very similar attributes (such as redundant or empty meta) and none have behaved this way. The broader question is how to do we get the indexing back ?

Hey Jason,

Did you notice that ALL the pages in your site are lacking descriptions?

Your description tag is empty. You can also see the result of that in Google doing a site search. Almost all results have the same description.

Another thing I would consider is fixing the text. Why is it all in caps? It's not only annoying to see in the site, but also in Google's search results. Just put the caps where they should be.

Other things I checked were fine.

Did you verify that subdomain in WMT?

I'd second Federico Einhorn...  He's correct about the description tags.

I did check the robot.txt file (looks okay)

And the meta info also looks okay, too:

<meta name="<a class="attribute-value">google-site-verification</a>" content="<a class="attribute-value">ruda0O6aWmbMZZc-UyJEYH4lx6e8T41glM3QIo_Ae7Y</a>" /><meta name="<a class="attribute-value">robots</a>" content="<a class="attribute-value">index,follow</a>" /><meta name="<a class="attribute-value">GOOGLEBOT</a>" content="<a class="attribute-value">index,follow</a>" />

But I agree that it might not be included in Google Webmaster tools correctly, due to this message:
