Is this search engine-friendly?

My url system

[Fall]

Hi,

I have a dynamic system. Most of my urls are friendly on the eye, almost just like static urls. Like this:

ht*p://www.******.com/?/about/
ht*p://www.******.com/?/tutorials/
ht*p://www.******.com/?/comingsoon/

It works like this: index.php receives the query string and gets the right content based on this string. The urls look like normal urls, except for the question mark in them. Is this search engine-friendly?

Thanks.

If it's a simple string like you have portrayed then it's not a problem, at least for Google, Yahoo and MSN Search.

To see, go to one of those engines and search "site:www.walmart.com". Click on page 5 or 6 of the results where the products start and you see it's all dynamic URLs.
