As you have hopefully already seen, I have a number of short stories on Kobo. I am in the process of recording reading/performance for audiobook versions, but haven't quite got there yet. Today though, I have uploaded another short story, and have done a few things differently.
Firstly, I have started with a price. Initially the first dozen stories were free, but some of the Kobo infrastructure doesn't kick in with that model. It still hasn't kicked in for the now $0.99CN books. Second, it is the first offering which is in the same series as something already up. That should be another way to link stories on the same page - vs hoping people click the author name and search that way.
Right now I'm just filling time till the words are checked against the guidelines (not hateful or pornographic). A process that can take "up to 3 business days" but for me so far is usually done in 2-3 hours.
As far as 'sales' go, it depends which dashboard I look at. It's either 20 or 26 - all of which from the 'free' era. Minus the fact that I've downloaded all of my own so minus 14 from that. So far scifi and detective genres seem to be doing the best.
45 minutes later: Well, it looks like the story has passed the check, and it's only showing the series link, but at least that bit works. It might be an idea to link all my short stories into an umbrella 'One off' or something. Unfortunately the preview is only showing the title graphic, and the length estimate is still not showing. And now since it's not free, I have to run around a different way if I want to get it on my own ereader...
