Do google bot still index and give PR importance to URLs that contain number? e.g. http://www.kedoya.com/item/382786.html Is URL without number is better for SEO purpose? Thx!
There is no problem with numbers in your URL, google-wise. But unless the number is one of your keywords, you would better use one of your keywords instead of the number!
The number in you url shows it's a dynamic url. It is more trustworthy both for bots and browsers to see that it is specifically named url rather than just unknown characters.
