Twitter based marketing – First step: You should think of your Twitter account primarily as a way for your fans and visitors to stay up-to-date with your business and your industry and as a way for them to ‘subscribe’ to your content when they decide they want to see more of you.
And remember too: People don’t tend to become fans of a brand after a single interaction. They need to have multiple interactions with your brand before they’ll start to get a full understanding of your mission statement and what you represent. What’s more, they need to see you multiple times before they’ll properly remember you and thus start seeking out your content actively.
