The goal is to make a thunderous roar.
Here are a few things I learned from my campaign. I'm taking a page out of Stuart's blog, One More Reader. He did a great post on this and inspired me to share my findings.
Lesson One: Sooner is better
Lesson Two: Sales pitch
Another thing with this is, halfway through, I changed what I wanted the tweet to say. This had the effect of everyone who supported me after that, sent out a different tweet. I'd recommend having a few different pitches and changing them during the campaign so your supporters are blasting different tweets. Makes it less spammy feeling.
Lesson Three: Don't expect miracles
Thunderclap seems to be pretty popular, so it may just be turning into white noise people ignore. In the FB group there are new ones every day. Will that deter me? No. It's a good tool to get a message out to a lot of people. The click rate might be tiny, but the more people you can reach, the more clicks you will get. It is a good tool to have in your arsenal. Of course, like with anything, that may change later. It might get oversaturated or fizzle out.
Anyone care to share their experiences with Thunderclap? Good, bad, and ugly, let's hear it.
