If you're going to use only one other social media outlet besides Facebook, Twitter should be it. Still one of the fastest-growing networks, Twitter enables users to communicate by sharing thoughts written in 140 characters or less, called “tweets.” you can add links to your tweets, giving people access to your site, products, videos, blog posts, and other areas of your site (or other sites you think are interesting).
While people who connect to you personally on Facebook are called “friends,” and people who connect to your business are called “fans,” on Twitter people who connect to you or your company are called “followers.” When you first join Twitter, you'll have no followers. When you send a tweet, it may feel like nobody's listening. You can build up a following by doing a few things:
Of course, just as you can buy your first batch of fans for your Facebook fan page, you can jump-start your Twitter following by buying your first bunch of followers by using a site like fivver.com .
Once you have a following, tweet info about your site and company, but don't oversell. It can't be all about your site and what you want to promote. Send tweets to articles that you find online (on other sites) that your followers would be interested in and that relate to your site. For example, if you're selling automotive aftermarket products on your site, tweet links to articles about new car models that are coming out, car shows, etc.—even if they appear on other sites. This will help establish you as an expert in your industry and build your following among people who want the information you can share, but don't want to be sold to all the time.
