How to add lots of copy

I've decided the only way I will get ranked high on the first page is to add lots of copy on my pages. Writing the copy will be no problem, but I'm unsure where to add it. If I do a large write up on my category page then customers will have to scroll way down to get to the items. I think this will ruin user experience as I'm sure most are there for the items rather than the copy. I'm thinking about having a separate information type page from the items page and just link them together, but then my high ranking landing page won't have items on it. Curious what other people have done.
