Quote by MC1982
Wife-lovers, cheating and cuckold could all be united under 'Infidelity'.
Well, yes and no. They are similar, but Wife Lovers and Cuckold are usually with the knowledge of both parties. Cheating, not necessarily. So people who are after one particular flavour might not find what they want if they are all together.
We also have to consider search volume. The word "infidelity" is all well and good, but who Googles for "infidelity stories" compared to "cheating stories" or "cuckold stories". I can almost guarantee the search volumes for the latter two are greater. We can't (and shouldn't) foist our internal naming convention on the outside world because it will hurt SERPS and traffic.
Some argue categorisation is pointless. And I tend to agree. Taggingāwith the first tag being the dominant themeāwould be more flexible but we currently limit tags to 10 (historically for aesthetics and performance; less so now) and the order of tags is system-defined, not user-defined. If those situations were to change, categories could become less of a thing. Barring the Omnium badge, which is a nice stretch goal for authors who want a challenge. Lack of category does, however, assume that everyone who submits a story knows that the first tag (or the earlier listed tags) are the ones that carry the most weight.
What would have been better, with the benefit of hindsight, is perhaps a category tree. So we could do what you suggest and house Cuckold, Wife Lovers and Cheating under an "Infidelity" parent. That gives us one more search term, separation for people searching for specifics, and a nice hierarchy to show the relationship between the terms. Similarly for other genres.
As for the Novel category itself, my main beef is it isn't a genre and people don't often look for "erotic novels in any genre". Search results will certainly consider keywords inside a story when returning matches but thematic content (e.g. supernatural) is harder to detect by search alone without specific markers.
Sure, AI searches allege to make semantic links from content, but it's computationally expensive (environmental impact too) and I've seen little evidence they're accurate yet. Having a category that the author states "this is what this chapter contains"āa bit like the ratings warning on Netflix shows that lists the themesāis a more weighted indicator that search tools can sink their teeth into and help people discover content they're interested in.
