Rand Fishkin has been running an experiment for a technique that relies on blog posts to drive up Web site traffic, detailing a senario using LastWear Clothing. He began tinkering with the idea after seeing a disconnect between those who naturally earn signals that engines look for, such as blogs and online communities, with those who need them, such as commercial Web sites. He believes the two can co-mingle, and tells us how to stucture the task. Fishkin explains that when buying a blog or any form of online community, the search expert not only aquires links, but also gets an ongoing method to pull in links, tweets, shares and +1s.
