I am in the middle of a project for a client (University) and was wondering if anyone can shed some light on an search engine optimization (SEO) and information (IA) issue.
At the moment they have hundreds of courses - often with similar titles and content - structured in a monstrous way, with a convoluted IA. Unnecessary pages, subjects, sub-subjects, sub-sub-subjects etc all to accommodate the number of course pages they have.
I am proposing to apply e-commerce style filter navigation for finding their courses and pool all courses under the same URL, in the same folder rather than fragmenting everything under multiple pages.
Their concern is that flattening the IA and moving everything up will affect their SEO in a negative manner.
Does any one know if that is correct?
