URL Confusion and How to Fix it

Search Engines strive to rank the best possible search result using the cleanest URL.  This means, if you provide them any URL-wiggle room (several duplicate versions of the same page all on unique URLs) they could choose one version of a URL over the others, you may not expect the one they choose, this will throw off your website’s ability to rank for important keywords, that in turn will adversely affect year-end traffic numbers, resulting in your receiving a huge lump of coal in your Christmas stocking.

Obviously, SEO in general is not that simple, but the challenges of URL Confusion sort of are.  In a nutshell, any URL related SEO issue which is visible to Search Engines during their normal crawling activity increases URL Confusion.
