Im thinking of putting something like keyword.com/keyword/keyword.html would this in the eyes of google be keyword spamming? The keywords are all the same.
It's best to mix it up a little. Maybe you should concentrate on a couple keywords: keyword1.com/keyword2/keyword1.htm
not sure if it is wrong in the eyes of the search engine but it's not really user friendly. Multiple "/" in the url make typing it out annoying. User experience aside (assuming it doesn't affect you) you might want to just use hyphens "-" and put the complete phrase or keywords within it. I see articles on Ezine rank very well because the whole title is spelled out within the url. P.S. just realized you said the keywords are all the SAME. Actually I think it works better than most realize. I noticed a website that utilized this and ranked well for the term so I know at least example.com/example ranked well where example literally was the same word. Not sure if your throw in another example.com/example/example how effective it is. If 2 works (which I've seen done) go for 3 and see how it goes.
