Does this work as a tactic for including keyword in URL structure

Howdy,

I'm planning out a website and need to plan out the URL structure for best SEO value. Generally I would do something like this:
site.com/widgetssite.com/widgets/large
site.com/widgets/large/blue
etc.

I think this is a pretty straight forward SEO tactic. The issue I have with it is in terms of natural language the "thing" you are searching for in this case is a widget, so typically you would type/search [adjective] [noun], or in this case "large blue widgets."

So one proposal I have is to instead append the "widget" to the end of the URL:
site.com/large-widgets
site.com/large/blue-widgets
site.com/large/blue/square-widgets
etc.

Obviously this breaks the whole silo concept since the square-widgets page is inside the /blue directory but the blue widgets page isn't at /blue it is /blue-widgets. My solution is to setup 301 redirects from /blue to /blue-widgets (even thought there are no site links pointing to that page).

Does this seem like a good idea? Or does this break the whole folder silo concept? What I like about it is that it feels more user friendly in terms of natural language and for certain high value keywords we can get certain pairings of words into the URL more like how a person would type them in.

I like your idea a lot!  I think as web and computer people we sometimes get too hung up on the historic teachings of our predecessors.  It's a good idea to change up the conventional wisdom sometimes.  Are you building the site with a CMS platform so if you decided the link structure didn't work for you, you could easily change it and it will auto 301 the old links?

In general though I think your idea is awesome and I'm curious to hear if it helps SEO at all.  I know google does care about directionality.  For instance I rank higher for NBG Networks than for Networks NBG so your theory sounds like a winner to me.
