On what basis should your company decide to join and be active in a social network? That is the question presented in “10 Questions to Answer Before You Join A Social Network”. This is an important decision for marketing and promotion now and especially the future. First, and most important, there has to be an audience already active with the network. This is a characteristic of the “Network Effect”, that the network in question is really on valuable if you can connect with other users. Think of the first person to own a telephone. They didn’t have anyone to call, so really it was just a symbol of their wealth. Further, in terms of promotion, your given audience (demographic) has to be involved in the network, which should go without saying. Another key factor businesses should consider when deciding to join a social network is, “Does the network solve a unique need for my audience?” For instance, a business providing legal services is much better suited to become active in Google+, rather than Instagram for example. The Google+ page will contain contact information, reviews and location, whereas Instagram is solely a place for sharing pictures… highly irrelevant. Also, the amount of work/effort it takes to be a successful member of the social network is also significant. Posting all day on Twitter does not necessarily translate to success. Gaining followers takes time, and for smaller businesses it might not be worthwhile.
