Just like it works for a website and blogs. The more Twitter linking going on within your profile, the more Google is seeing your Twitter profile. So if you are company wondering how to get your posting on Google results. Focused first on a very well design campaign to get as many followers (who are really interested) in what say.
Now, doing a mass following like the spammers do,isn’t going to improve anything. In fact the only possible result of this would be making it worse. Use word of mouth and offline social networking to increase the amount of lists and followers. Follow only people who are ralated to you business (in the SEO Case Matt Cuts, Google and so on).
The same way people don't want to receive unsolicited emails from you. Is the same way their will not be expecting to follow them in twitter. Remember Quality over Quantity rule.
