Only commenting from my personal experience, so might not be correct for everyone. I always look at grammar & syntax, I run alot of high narrative games so I feel its important people know how to do proper speech. Personal details that better define you also help make you stand out a bit more, shows you're interested in being seen as a person, not just a player. Show some creativity as a player, no particular way to do that though. Mainly I look at what people say in the LFGs I posted, & again, this is just from my own perspective, I know some GMs do first come, first serve but its a GM's market so its understandably difficult to get a game. I try to make sure all the players I take are compatible with the group & everyone has a good time, I'm not trying to just assemble players, I'm trying to create a potential group of friends is more how I look at it. General advice on posting an app, don't be too familiar when you write, it can be seen a bit weird. Don't give blanket answers like "Ive played RPGs for 10 years & I'm very easy to get along with", pretty much everyone says that, another difficult one is when I ask people if what kind of campaigns they like and what part of the game they like & 99% of the time the answer is "anything/everything". I get its difficult to find games but not every campaign is for everyone, I never take people who do the cop-out answer JUST to get in the campaign. Overall hope this general information/rant is useful to you.
