A common question I get is WHY the heck do I need to bother with Facebook and Twitter .. etc!
Well, as I regularly explain in my marketing classes, these social systems are great mechanisms for engaging a broader sphere, presenting yourself as a knowledgeable expert, and also bringing traffic back to your real estate website.
Of course - these are all behaviours that we'd expect Google and BING to be interested in, and now its official. This article and interview by Danny Sullivan of SearchEngineLand.com is facinating as it shows how the big search engines view social media today and what this means for all of us.
Bottom line? Yes, Twitter and Facebook are watched by these guys and your presence and activity there will influence their view of your authority and ultimate affect your site rankings.
