No one can remember every genre they like, especially when you have plans on going into detail about each. You're going to want to be specific here, though.
If you say you're interested in historical, then be sure to specify if you only like a specific era. If you say you like "historical," but you really mean you like to play Age of Sail and someone messages you wanting to play historical, but they're thinking something more along the lines of 1920s NYC, then you're both going to walk away disappointed.
Additionally, the same goes for fantasy. If you're thinking about vampires, werewolves, and shifters (oh my!) and they're thinking about fairies and nymphs, then there's definitely going to be a disconnect. See what I mean?
Let's talk about fandoms. In the same way, make sure you're specific. If you say Harry Potter but you're really only thinking about Marauder's Era, someone's going to be disappointed. If you say Star Trek, but you're really only thinking about Next Generation, then the same issue is going to happen.
While we're on the topic of fandoms, let me remind you to always indicate whether you're looking for canon (already created fandom-specific characters) or OC (writer originals). If it varies by fandom, include that, too. You can even go crazy and specifically say what pairings you look for (ie; Harry x Ginny) and which character you would prefer to play in the pairing.
This also might be a good place to indicate any specific plots you're looking for. If you've got some great ideas, but you're having trouble finding someone to write them with you, having your plots posted (while scary, no one wants their idea stolen), can also help you find a player to write an epic story with that plot you've been dying to try out.
