Welcome to the Q&A Forum

Right now the page looks like a link farm . . .

My client has a live page with 100+ links subdivided into 10 categories that each have great potential keyword targeting opportunities.  I'd like to improve this page and my intuition is to split it into 11 pages, one page with links to all the others and a bit of content about each.  Here's an example of the potential IA:

Dog Rescue Groups
   Golden Retriever Rescue - description
   Poodle Rescue - description
   Cocker Spaniel Rescue - description
   Poodle Rescue - description
   Labrador Retriever Rescue - description
etc.

---------

Golden Retriever Rescue
   Link 1 - description
   Link 2 - description
   Link 3 - description

Is this a good idea and will I see a big traffic drop overall at first?  Also, these are all internal links, not external.
