The number of Twitter competitions is increasing a lot recently. Many compers do not like that because of the need to have a Twitter account and remembering yet another password but that is that. Some brands really love Twitter comps because they create such a strong buzz. Shallow of course but loud and they think that really helps them with their marketing. Now that is a matter of debate but the fact is that they do run a lot of Twitter contests lately and if you want to win you need to learn how they work. There are basically a few variants of them. The simplest form is a simple following of a brand to be in the competition. So for at least the promotion period you need to stay a follower to have a chance to win. That is easy enough. The next level would be the need to re-tweet anything that the brands require you so that your follows in turn also get the message. Alternatively, you need to do a tweet with the hashtag indicated in the rules. This may also add a creative component as you are normally supposed to tweet something original or funny to that hashtag. It could also turn into a question and answer type of competition where you need to answer some kind of quiz for your chance to win.
