Over 20 Categories, No Keyword Strategy, Can someone help?

[Sizmic]

Hello Friends,

I have recently built a big site with nearly 300 pages (to begin with) and there are around 20 categories on the website. I want to get 3-4 keywords ranked for each category but I don't know how and where to begin. My site revolves around wedding industry but does not have a "Main Keyword" - not yet at least. A couple of "Main Keywords" (these keywords actually describe my website) that I thought of have ZERO traffic but I have few good keywords for each category.

Can someone please suggest how do I begin with?

Regards,

Naimath
