Reg. Search engine optimization for my blog

I'm on the way of creating a blog through ASP.NET MVC framework. All the articles I'm going to submit have the same layout only the main content differs. So I created a common view that dynamically loads the content from a physical file(contains only the particular article markup) in a section. So all the url requests send by users points to a same physical file that dynamically loads a particular section based upon the article. Is this the right approach? Is this create some problems in SEO? I'm eager to hear from you. [UPDATED] The urls of the articles look like http:开发者_开发知识库//myblog.com/blog/archives/2011/1/using_asp_mvc. All these kind of requests are received by a single page that loads the content of the article from another physical file in it.

I think you need to rewrite the url like in

http://www.cricandcric.com/Cricket-News/4182/Cricket-West-Indies-:-I-am-sure-that-West-Indies-will-bounce-back-,-said-Hooper.html

If you obesrve this I have done the URL Rewriting, which will be user friendly for the search engines.

You can find good references at following url

To make it more understandable about the power of url rewriting if you search for "I am sure that West Indies will bounce back , said Hooper" in google, you can see our cricandcric.com in the first page
