Hi Gaston,
It's a little difficult to explain without giving project details out but it's a little like this -
The company specialises in glass, they supply and fit a wide range of glass from other suppliers, so there are categories for each company that makes the glass and then the individual types of glass inside those categories.
e.g. Pilkington Glass - The Company that makes the glass. PyroClear - the product they make.
The first landing page is for fire glass (a general term), which then has a side navigation for the companies that make the glass, currently they link nowhere but on hover they show the more specific products which then link through to the pages.
But it's problematic for breadcrumbs etc, if someone click the brand of glass it just redirects with a 302 re-direct to the fire glass homepage. which could frustrate people and increase bounce rate.
Currently these categories just use a 302 redirect, I think there may be an opportunity to make these category pages into landing pages for broad search terms, which can then link to the more specific products. it would be more logical for the breadcrumbs and could serve a purpose for SEO.
I hope this makes more sense!
Lee
