Oooh, I’m not the best person to ask this because I’m still fairly new and getting used to WP. xD I just returned to this site after being only on it for a few days when I first joined, lol. But it’s simple to tell exactly what kind of stories are prevalent on this site for even newbie users. I also hear so much from word of mouth and on other sites since WP is so huge.
For promotion, WP in general doesn’t have any good promotion methods. It’s partly because they hold an enormous amount of stories and the largest community, but also because they don’t have the best algorithms in place to support new or niche stories, especially stories like yours which are allegorical. Thus, those that search for niche, are very small. And then, it’s hard to break into the larger audiences because it’s swamped.
I think also the difficulty lies with your story being so short. I don’t mean for you to lengthen it as I believe it packs more of a punch this way. It’s also very clear, so I wouldn’t like to see it being “diluted.” Even if a site had better support algorithms in place, most readers wouldn’t necessarily come back to read it again or share simply due to it being a one-shot type story. This is more on reader behavior than anything else.
And as you mentioned, this type of topic is hard for some to digest. In fact, without my prior knowledge and interest in deeper human, ethical, and philosophical+psychological issues, I probably wouldn’t have picked it up. I might not have even grasped the depth of the significance being conveyed either. I definitely would have understood the whole reveal of wolves as being the same as sheep, but I would not have understood what this speaks about and entails for humanity. So in that sense, many readers wouldn’t be able to properly appreciate the artistic and meaningful purpose of your writing and intention.
This would serve as good dip in the feet for similar, but longer length stories of yours. I just don’t think that on its own, it can be promoted very well. But used to promote other longer stories of yours, yes, I think this is possible.
The best tactic is to do what you’re currently doing, asking in the forums. Maybe you can start a topic on war and human nature allegories and then subtly tie it in with your story—like, I wrote this type of story topic, but what do you think about the popularity of interest of such stories? how can it be appealed to a larger audience? By engaging in a wider discussion, maybe you can get more bites on your actual story and eventually people who are interested and care to read stories in that topic.
