If you want to build a big social media following, as quickly as possible, Twitter is the place to do it.
A new account is allowed to follow up to 2,000 users. Start by following relevant users from accounts similar to your own (competitors, partners, industry news outlets etc.), until you hit your limit. Then, periodically unfollow users that haven’t followed you back – and follow new, relevant users in their place.
As long as you do this gradually, you won’t fall foul of Twitter’s fair usage rules. You’ll earn follow backs, and even find your account recommended by Twitter – and you’ll be able to grow your account to 2,000 relevant followers extremely quickly.
