Schema.org - Right way to mark the pages

[te_c]

Dear all,

Almost since we started designing our site, we are using schema microdata. It is not only because of the rich snippets, but because I want the search engines to better understand what we have.

For example, the +1 buttom would not work properly without schema microdata, because it kind of ignores the OpenGraph parameters that specified image and description; and since we are a (very small) local bussiness directory (between other things), all our clients have a hand written schema complient description on their lisings, including address, opening ours, telephone number, description, etc. It is hand written by us because the tools avialable are simply not good enough to cover all different scenarios that a listing can present.

I have not use, until today, a proper for the homepage, and it is probably the cause that our page lost the nice links below the site description in the google snippet. I did not place it on the body tag, but near the description, closing it inmediately after the description finishs. Now this is solved and we will wait to see if the links come back in the next weeks.

Now to the question. Our site has three sections, with three different systems installed, two running wordpress and a third running another script. the main site is the local bussiness directory. The front page is mark as "schema.org/WepPage", and I do not know how to mark the other pages of the main site. I was thinking of marking the listings as "schema.org/ItemPage" since they are related to specific clients. Would you consired it to be right? Then, we have landing pages for the categories, should they be mark as WepPage, or as an Article, or something else?

Many thanks in advance for your help,

Best Regards,

Daniel
