Yes, You can Manage to Your unlimited Twitter Account. I have some process-
Managing a Twitter account for a brand also means curating and developing their online community. Retweets, follows and favorites further express the brand's identity and help it connect with the right customers, partners and prospects. I once took over a local business' Twitter account and discovered that the agency who they'd worked with previously had followed nearly 2,000 Twitter accounts of people all across the country in an effort to build their community. The problem was, the vast majority of those people would never visit the city the business was in, let alone shop there. A good social media manager will develop a Twitter community that is relevant to your business.
