Many people never stop to think about it, but putting together a successful Twitter campaign goes well beyond what one tweets. While that is obviously important, the time at which the tweets are sent out is every bit as pivotal. It is the same rule that TV or radio advertising goes by, really – no ad is any good if it is broadcast at a time nobody is around to see it. But for some reason, such a concept is often bypassed by people who use Twitter, as if they thought the actual permanence of the tweets went into ensuring their readability.
Well, that should never be taken for granted. What one should do is use a service like Tweet When for figuring out the best time to tweet. That time is the time in which one will get more retweets. And this application can arrive at it simply by being granted access to your Twitter account. You supply your username, your password and then it will analyze the kind of people you interact with. The best time(s) to tweet will there and then be displayed for you to take ready advantage of such information.
