Twitter started out as a micro blog. In 140-characters or less we were supposed to connect. Now, the social network is so multi-dimensional that it has hired Edelman Public Relations to educate users about its functions. Also, a cottage industry has emerged to coach about using Twitter as a private network, a search tool, and to break news.
So, if you haven't made Twitter useful to you yet, you are not alone. And if you're discouraged that you don't have a million followers, be aware that doesn't matter. All that does matter is your ROE, that is, your Return on Engagement.
One bit of ROE you might be missing is in your search for a job, new business, and/or networking.
How you leverage Twitter is to front-load the keywords such as "General Mills," "David Caruso," or "mobile apps" in your message. This is the same approach you would normally use in search engine optimization [SEO]. Here is my article on SEO which has received more than a million downloads. And, here is my update on that which has been published on INDIE READER and picked up by Huffington Post.
Just about every organization and most well-known individuals monitor what's being said about them on the web. At the very least they use Google Alerts. General Mills, David Caruso, and those needing help with mobile apps are likely to know you're there, read your message, and maybe even begin following you.
Although the micro-blog limits the message to 140-characters, more and more tweets have become long-form. That's accomplished through pasting in a link to all that additional text. Before you paste in, you go to bit.ly which shortens the link. It's a free service. Then you copy that shortened message and paste it into your tweet.
