There is a practice going around called Twitterjacking. It is essentially using other people’s tweets, hashtags, and other Twitter marketing strategies to draw attention to your business. It’s controversial, but it can also be powerful if you don’t overdo it or misuse it.
The first step is to find popular Twitter users and hashtags in your niche and follow them for a while. Get a feel for what they tweet about before you do anything.
If opportunities arise, interact with these power users. Ask them questions or respond to their tweets. Focus on building a relationship first. You can even retweet some of their most interesting or useful tweets.
After you’ve built a solid relationship, tag along on one of the popular hashtags that are gaining traction. Rising hashtags are great opportunities. Make sure your tweet is relevant to the hashtag and to your audience. If possible, mention the originator of the hashtag or the associated brand by @ sign and name.
This practice, if done well and unannoyingly, will usually net you a few extra followers every time you use it. Just don’t abuse it.
Retweets, hashtags, and even favorites are all subtle but powerful ways you can hijack Twitter to attract a little attention to your brand.
