This image((1)) came to me via a photographer friend of my wife. This is clever in a charming way to think of social media though I definitely part company with the description of Google +.
I found this graphic from Social Strand Media that does a better job of describing a wider range of social media.
Once you get beyond the simplicity of the presentation and get over the simplifications, or, in some cases, errors in characterization of social media, these reveal an interesting opportunity to shape a strategy that is particular to your business. Keep in mind that the social media sites mentioned here are really just the tip of a vast universe of niche specialty social media sites. If you are a winery, there are social media sites where oenophiles hang out. Does your business involve native species of perennial flowers in the upper midwest? There are social websites for virtually every slice of interests. If you can’t find one that suits you, start one yourself. Open source social website software like BuddyPress is simple to set up. Web marketing is not necessarily big budget, just long on thinking and involvement.
So, the web marketing challenge here is to identify your customer base(s) and get involved with them. Keep in mind you need to drop the old pushy sales and marketing approaches and get engaged to share your knowledge and enthusiasms. Web marketing is engagement and sharing not pushing messages. Sales will follow.
