Separate Landing Pages or separate site structure

[mikep]

I have a query regarding this. Say, if you are selling (or renting) items of weddings. That includes everything from chairs to flowers, everything.

Now here is the dilemma. What should be more favorable to do in terms of SEO and also getting sales? Create separate landing pages for every product or just create separate site parts such as catering division, furniture division, flowers & designs etc?
