Here's what I observed.
- March 2006 = 25 Subscribers, 25 Daily Visitors (10 From Blogs, 10 From Google).
- March 2007 = 300 Subscribers, 100 Daily Visitors (40 From Blogs, 50 From Google).
- March 2008 = 1,000 Subscribers, 250 Daily Visitors (30 From Blogs, 175 From Google).
- March 2009 = 1,700 Subscribers, 125 Daily Visitors (30 From Twitter, 7 From Facebook, 50 From Google, 20 From Blogs), 400 Twitter Followers. Major change in Google algorithm in February cuts search traffic by 65%.
- Dependence on Twitter results in a lack of "link love" that fuels Google's view of your online presence. As a result, your Google "page rank" or modern equivalent if you will, doesn't grow at the same rate, and therefore, organic search becomes less effective, making it harder to develop an audience.
- Twitter, at 140 characters, makes it harder for the marketer to explain topics with any level of depth, and hence, makes it harder to develop credibility on deep topics.
- Twitter, adopted by 2 of every 100 folks in the United States, limits our ability to speak to the audience we wish to speak to. I'm lucky if 10 of my 400 Twitter followers would ever hire me for my consulting practice. At this time, Twitter is important for experimentation, but it is dangerous to depend upon it as a marketing channel.
- Word of mouth becomes more and more important ... we'll all need folks talking about us online and offline to fuel growth.
