Though it may seem a huge number, getting 1000 Twitter followers is easy when you define your target audience well. The need for targeting comes up when you want to have a meaningful engagement or translate the numbers into sales when you are promoting your business via Twitter. You can incorporate these two options if you want to target and attract even up to 1000 Twitter followers.
First, your profile description page. It is here that you let your potential followers know or confirm your personal details if there are several accounts with an almost similar username. Indicate your real names, job title if any, your workplace, interests and the location you are based.
The other option you can use to target such a huge following is based on information and keywords you use in your tweets. Everyone tweets for own reasons and intention. Those who love jokes, sports, and current news will follow respective accounts because they are guaranteed to get that information there. The moment you decide to tweet about everything and anything, you lose a huge number of followers.
