"3. Directory and Search engine submission
When I want to know the type of tasks they will do for my site and one of them is omnipresent - We will submit your site to search engines and directories. I am sure this used to work a decade ago but is not SEO anymore in 2011. You can always submit you site to top search engines like Google and Bing but even that can be avoided if your site can be found through a link from some other page or site which is indexed frequently by those search engines. "
by far the best;
i mean i see so many ppl still using directory submission while the important things like backlinks and socialnetworks are left aside
