Me and a bunch of friends are rgresteiing an I.T company but we're all inexperienced but relatively skilled. My job is to be the online presence . Running the blog, advertising on sites and search engine optimization. Since i know nothing about these topics, i'm turning to the internet for help. A comprehensive tutorial on search engine optimization, some help on web advertising especially on social network sites and a link to a similar establishment's blog that i can use as a model would be much appreciated.
