We're giving away a $100 Amazon Gift Card to whomever gives our product a name. We've tried Twitter (though with a new company we have few followers) and an individual with 700 followers, Facebook both personal and business and some banner advertising. I would have thought dangling the Amazon carrot we would have had a higher rate of response but so far its mostly been friends and family.
We've completely avoided public forums that we use so as not to engage in shameless self promotion but I'm a little perplexed on how to get the word out.
Is the word is out and nobody cares to participate in that kind of interaction?
Maybe these types of contests generate little response?
There are various ways you might want to go about doing this. I have marketed in the past and have found that 700 twitter followers on an account is nothing. I have well over a thousand following me and few of my followers would be likely to respond to a contest or anything like that.
If you have a budget, you may want to consider advertising your contest on a site such as Facebook. You could also give away something more personal feeling than a giftcard. If you can have second and third place winners, why not have a t-shirt with your company's name on it for a prize for them --- so people feel like they have a higher chance of winning.
Additionally, you could run to concurrent contests, one is a random drawing of people who help promote your contest and one is the actual naming contest. As it stands, the fewer entrants there are, the higher chance that any one of those entrants would win, so they've no reason to promote the contest. Give your contest participants a reason to help promote the contest.
There could be a few things happening here:
If all else fails - don't sweat it, name it yourself. You are sure to come up with a workable name.
Easier said than done.
