I use twitter for growing a following because I feel like that’s what your supposed to do in this age. But honestly if you want more leads facebook is the way to go for actual business getting done. I feel like twitter is better for selling things unless you have a service that appeals to the younger generation.
I dont market my business per say with Twitter. A common misconception are the people that create to blast advertisements about their business. Those types are worthless and never really see the benefit of Twitter.
On Twitter, you are in basic conversations with people. First, share what drives you or what you have to offer the community. As people around you gather you skills and abilities they may come your way. I every so often talk about something I am working on, but this is very rare.
I use Twitter much more to help people. They in turn know, I am knowledgeable and when they have needs they will come my way. Its sort of creating a word of mouth recommendation.
