Google's Maile Ohye presents a video aimed at SEO beginners on building an SEO strategy.
"Maile Ohye describes how to create a holistic SEO strategy inclusive of all your company's online channels (website, blog, social media channels). She uses the mock company, Webmaster Central, and pretends to be the SEO manager of the Webmaster Central Blog."
It's worth bearing in mind that this is Google's message, so you should bear in mind there are other analytics and ways to measure, analyse and manage your SEO strategy. Well, there used to be before lost of data went in-house with Google. ;)
