Avoiding duplicate content in multiple categories of a directory site

[hotelmarketing]

I am struggling with finding a solution for a duplicate content issue and wanted to run it by you all.

I run two professional directory sites broken down by multiple categories and geography. The listed professionals typically list under multiple categories and geographic areas. The rub is the same information is published on each category and geographic page. One of the sites was hit on June 4th. To address the geographic duplicate issue, I plan on reducing the geographic pages, limited the number of geographic pages professionals can list under, and adding a wealth of new listing information. The new listings info will only show in a single category and geo page. What I am trying to figure out is how to differentiate the existing professional listings from category to category. Couple of thought I had are using javascript to publish the listing in the second, third, etc category page, requiring unique category descriptions (same contact info exists) Any suggestions would be appreciated.

Having the client write a unique blurb for each category where they want to appear would be the optimal answer. Every other approach i can think of takes the direction of hiding something, but that approach would allow completely visible content for Google - and full indexing.

If the categories are distinct, then having a separate write-up tailored to each one sounds reasonable as well.

Another alternative is to simply provide the outgoing URL to a different page on the clients website (i. e. different product or service).

Appreciate the response. Close to hiring another salesperson, oh I mean writer.
