I would suggest simple solution
After Header of your website , Middle content Start with
[Impressive Word] Category
Piece of Content about Category , main products , features...
After that Product listing with order of Top Selling or Featured Products..
No one is interested in lengthy content in Category or even in Product Page (not even search engines).. instead of that I would suggest use that space with
to list Last Buyers or visitors who visited this category has also visited this category kind of feature
