Would it be worthwhile to update URLs to include "for sale"

[DealerskinsSearch]

My team is new to the world of SEO.  We were both in other departments when our last "expert" left and we became the entire department.  Needless to say, we have many questions.

I have a site for an existing customer - she wants to know if it is a good idea to change her URLs.  She went to a webinar that suggested she include "for sale" in URL, since that is the site's primary purpose   These are the current inventory URLs:

http://www.dealerskinssite.com/used-inventory  http://www.dealerskinssite.com/new-inventory

The change would give something like:

http://www.dealerskinssite.com/used-cars-for-sale
http://www.dealerskinssite.com/new-cars-for-sale

I did some searching and could not find a solid recommendation one way or another.  If it is true that people typically search for "used cars for sale" rather than a "used inventory", then there might be benefit to including that as part of the URL... but that is as far as my knowledge got me.

Please let me know your thoughts

Klarke,

Thanks for the response.

I guess I should have just reasoned it out.  The statistics are staggeringly in favor of Used Cars over either of the other two (see image).

This might even be worth getting a permanent change in place away from our standard of Used Inventory.

Changing that isn't likely to result in much improvement.   It might actually have a negative effect if proper 301 redirects aren't in place.  And even if you do the 301's correctly, there's no guarantee the search engines will see it the same.

You'll get better mileage if you change the page's titles and the content to better satisfy those keywords.

Also rather than listening to what other people say, you should probably check the actual search volume of these keywords and compare.
