When building your websites more than another?

Just recently i have started concentrating more on 'household' related products because they dont seem to have as much competition for that type of traffic.

I actually found that a little weird to, when i started with this household stuff i figured that area would have the smallest amount of sales but, its actually one of the top sales generating sectors we're working in at the moment.

So how about you folks? Are you finding yourself concentrating more and more on a specific area when it comes to the types of website or webpage you are building?
