Before I get to my stats, though, I have one more tip to share. When writing the tweet that will be shared, NEVER write it in first person. Always use third. I've had a few TC tweets where I got friends congratulating me over a release that wasn't mine because the message was similar to "My new book is here!" This is important because, as I personally demonstrated, people trust the message you've written and may not read it before supporting. TC is very much an "I'll scratch your back if you scratch mine." (Which is why I recommend varying your messages to be less spammy.)
Anyways, on to the stats.
Support does not equal clicks.
Don't overburden your message with hashtags.
The question is why did Jophiel succeed?
- They've uncovered a truth more dangerous than Joe & his brothers could imagine. #PathOfAngels #NA #urbanfantasy
- Mariangela holds a secret that could destroy Joe. #PathOfAngels #NA #urbanfantasy
Do either of those seem compelling? Was it the people blasting the message? Jophiel's story sounded more interesting to their followers. I did have plenty of people support all four campaigns. Honestly, it's anybody's guess. (It could also be Zadekiel was the winning campaign, but I am horrid at math and still use my fingers to count.)
Like most promotion, TC can be a matter of luck. The right people see it and think "OOO! I need that. *Click*". I stand by my statement from part one. Thunderclap is a good tool to use for promotion, but still has the risk of becoming over saturated. By then, something new will take it's place and we'll start this dance over.
