Sam222, here's the link to what I referred to: [support.google.com...] It does sound like keyword stuffing, but their take seems to be that it's more useful to visitors.

A site's URL structure should be as simple as possible. Consider organizing your content so that URLs are constructed logically and in a manner that is most intelligible to humans (when possible, readable words rather than long ID numbers). For example, if you're searching for information about aviation, a URL like [en.wikipedia.org...] will help you decide whether to click that link. A URL like http://www.example.com/index.php?id_sezione=360&sid=3a5ebc944f41daa6f849f730f1, is much less appealing to users. Consider using punctuation in your URLs. The URL http://www.example.com/green-dress.html is much more useful to us than http://www.example.com/greendress.html. We recommend that you use hyphens (-) instead of underscores (_) in your URLs.

Also this page, which references the above page: [support.google.com...]

Use informative URLs. The URL (web address) of a page appears below the title, with words from the user’s query in bold. Your URLs should be simple and human readable. Which do you find more informative: http://example.com/products/shoes/high_heels/pumps.html or http://example.com/product_id=123458?

I'm assuming that they give you some leeway on URLs in terms of keywords, since having the keywords there is actually considered useful for visitors. I'm sure there's a limit, like I'm guessing that "stuffing" would be something like including synomyms, and plurals and singulars, like:

http://example.com/green-dress-dresses-jade-emerald-forest

But as long as you keep it simple, the quoted examples above are what they advise.
