I have started a new blog on Wordpress. Which permalink sturcture is best for SEO? I read somewhere on net that using the permalink stucture like: www.myblog.com/blog/%year%/%month%/%date%/%post-slug% is more SEO friendly as it has got time of posting or HOW OLD THE POST IS (in search engine terms)... Also I got another suggestion that using just www.myblog.com/blog/%post-slug% is Optimal... So please suggest me the BEST SEO friendly permalink structure...As once they are implemented they cant be changed...
