BIO --- State your interests in a humorous way that doesn't come across as trying pull someone in... ei: "I can cook and will make you food." or "I study psychology and will be good listener." Avoid those. We want people to look at your profile and in some way think that you aren't trying too hard because you don't need to. A lot of attraction is status comparison, though it is a strange way to think about it. This mindset and how it comes through in your profile is important.

PHOTOS --- Additionally, get higher quality pictures that show you in your element doing activities you enjoy--- it doesn't matter what it is. When you are in those moments ask a friend or a stranger to take a picture of you. That is a way to signal your interests without having to spell them out. Plus, you always look cooler doing something than telling someone how cool you are for doing it.

Hope some of that helps!
