I resisted setting up a street team, worried mine would fail, but taking the plunge has been one of my best career decisions.
What is a street team? A group of readers who are your biggest fans. They are your cheerleaders. Those who want to shout from the cyber rooftops that your books rock.
How do you set one up? You can get as fancy or elaborate as you want. For me, I set up a closed group on Facebook and then invited those on my author page who were interested to join.
How is it beneficial? That depends on what you believe you need as an author. This is what mine is for: Members of RaShelle's street team will receive advanced reader copies of her books in order to post reviews on Amazon, GoodReads, etc, and help spread the news of new releases...
It's really simple to do. I've only had mine set up a few months and have already reaped the benefits.
