I have to agree with sunkist219.
Social media is not the place that you would want to use for insurance. Online marketing is basically online advertising. A simple rule of advertising is that you do not advertise a rock guitar in a gardening magazine. Each form of marketing has it's own place.
There have been case studies about social media, like the one done by an
SEO company with a viral post here
SEOmoz | Anatomy of a Super Digg. the title of the post was "8 Diseases That Give You Superhuman Powers" that is in question.
They talk about how they got wild traffic from social bookmarking, but it was for an auto dealer. They also state that they increased in natural position, but that the page that went viral had no links to any page within the core site, just residing on the domain, so there was no
PR bleed from the viral page.
Now, here is the kicker, he had already stated that he was link building for a month, and then after aweek or so of the viral that the natural went up on the site itself, but no way for the links to that page to share gained link power or
pr bleed.
So, was the first month of link building what made the site jump in natural, was it just that it took 5 weeks of normal link building for the big "G" to credit them and readjust the serps?
I would bet 1 million on that! It was the couple hundred links built over the month that made the difference for the core site as he still stated that the viral page still did not rank for it's own title.
If you look at the way viral works, you must have a mass of people interested in what you have to say, If you notice in the post that he had little, if any results from other attempts on targeted viral within the market he was working and that is why he done the 8 diseases thing.
Viral is good for certain sites, great for others, and poor for still others.
He would be much better off doing a steady link building program and/or PPC if he wants good and qualified traffic to the site.
