Welcome to the Q&A Forum

I am looking for advise on how to best start adopting schema.org for a real estate portal.

Would like to get feedback and suggestions on my initial thoughts.

Here are the obvious ones:

1. http://www.schema.org/RealEstateAgent(Thing > Organization > LocalBusiness > RealEstateAgent) Plan to use this to wrap realtors' information.We ll start with their profile page but possibly also on other pages with their information (e.g. listing page) 2. http://www.schema.org/SearchResultsPage(Thing > CreativeWork > WebPage > SearchResultsPage) This will mark search results pages where e.g. multiple listings of certain type in certain area are presented. 3. http://schema.org/WebPage(Thing > CreativeWork > WebPage) Pretty generic so we are thinking of using it on every page. e.g. significantLinks and breadcrumb objects seem like they could help in marking important links that will help search engines understand the site's information architecture better.

I am not sure how to treat property listings Offer seems a good fit (http://www.schema.org/Offer) but not perfect. maybe it should be combined with place (http://www.schema.org/Place) http://www.schema.org/GeoCoordinates could also be used to mark each listing's location on the map.

any thoughts or experiences you would like to share?

I would optimize for singular if keyword tool indicates more searches for that.

On the other hand I presume search engines become better and better in recognizing singular vs plural and consolidating search results accordingly. So in the long term maybe this wouldn't/shouldn't matter?
