Suggestions for a Job Portal SEO...

Hi,

I am still stuck in the beginning stages of web design & architecture for a Job Board Listing Site for Dental Jobs based in USA.

I was looking at design of one of the popular sites careerbuilder.com

When I visit http://www.careerbuilder.com/Jobs/Channel/Health-Care/ and type some random search say "XYZ123".

It opens a dynamic search result page where an automatic Meta Title is created and canonical url is inserted which is <link rel="canonical" href="http://www.careerbuilder.com/Jobs/Channel/Health-Care/Xyz123/" />

So basically this url gets created the minute a search is made (be it any search) - http://www.careerbuilder.com/Jobs/Ch...h-Care/Xyz123/

Also Second Case

Lets say I search for "New York". Search Results appear on a dynamic URL whose canonical URL automatically inserted is <link rel="canonical" href="http://www.careerbuilder.com/Jobs/Channel/Health-Care/New-York/" />

Surprisingly the url http://www.careerbuilder.com/Jobs/Ch...Care/New-York/ is indexed in Google. How is this URL even being indexed as its a dynamic URL and not even a fixed page but just a result of search keyword...

Is this SEO Friendly Design?
