There is not just one way. You have to do several things simultaneously.
First you should use twitter search option. www.search.twitter.com. Input your keyword or words and follow everyone in that list. Change your words around to get more people. For example, if you are looking for internet marketing, input internet marketing follow all those people. Then input online marketing and do the same and so on.
You should post three or four times and hour to keep your followers updated with all of your activity. If you have a Wordpress site, you can use the Tweetily plug in to automate your tweets by posting your posts randomly at a scheduled time. Mine is set for every 12 minutes. In order for that to be successful, you must have a lot of quality content on your site.
You should put share buttons on every post and page of your site.
You should have social icons to all of your social site accounts for your readers to visit and follow.
You should also tweet about different things you are doing in addition to your automated tweets. For example if you set up a Squidoo lens, or publish a press release or have a great resource to share tweet about it
Set up your twitter lists. Create lists for sub categories of your niche. For example if your niche is internet marketing, then set up a list for affiliate marketing, one for SEO, one for traffic generation etc. When you create the list you will have a box come up with hundreds of twitter users in that niche. Follow them and many will follow back.
You will see that all day every day you will get new followers just from following and they will share and share and you will see. You will get hundreds and that will grow too. Good luck.
Post quality updates everyday at least 4 time a day! follow other people in your niche!
