With Twitter the phase of “do we really need it?” is over. The “how do we use it?” phase is right now. There are numerous ways of using Twitter for everything from business to bull**** and even clients come up to me and ask me about Twitter after reading one of those Twitter articles in the main stream media.

So what are the Twitter tools that really make a difference for seo and overall business users?

We see at least a dozen new Twiter tools every other day. So I selected just 30+ Twitter tools that are most useful right now. Some of these tools have been around for a few months some have sprung up just recently. They have one thing in common: You must be aware of these tools in case you’re serious about Twitter participation.
