This is a very assertive tactic, but it works. Twitter eliminates geography and makes it so that people who think similarly can connect with one another online. That means that you have more opportunities than you ever have before to connect with people, even those who are in niche markets. That means that your audience is likely already out there, you just have to go find them.
How do you do this? There are a couple ways to go about it. First, you can search for users in a variety of ways. Twitter’s user search uses the information that people have given them and returns search results. For example, if you run a business that involves video games and gaming, then you can search for users who like those things as well. If you run a business in a particular region, you can search for users that are in your area that may be interested in what you are doing. If your business has online services, then you will be able to reach an even wider audience. When you find the users that you’d like to follow, follow them and invite them to follow your feed as well!
