Matt Cutts was recently asked a question about the position of keywords in the URL and its impact on rankings. In the following video, he tries to answer this question by saying that although, keyword presence in the URL does help but a person shouldn't get obsessed about it.
In the video, Barry Schwartz asks Matt whether one should go back to their old sites and include keywords in the URLs? In response, Matt says that instead of changing the old URLs it's better to consider this point when creating a new website.
Barry also asked Matt Ă˘â‚¬Ĺ“if all new sites should make sure to have keywords in the URL.Ă˘â‚¬Âť For which Matt answered that you need to keep two key points in mind such as content management system and useful keywords.
The questions put up by Barry would definitely help a lot of webmasters while creating websites for their business.
