How can i(23M) keep an engaging conversation online with her(24F)?

I(23M) met someone online, and we had some good talks about ourselves and i relate with her(24F), and i wanna keep talking, but we're both very shy and i just don't know what to talk about and i just keep bringing up how my day was or trying to invite her to play something, I don't wanna to become a reporter and just annoy her with questions and questions about her but i want to know more about her and talk with her about her interests without looking clingy or annoying. Any advices would be very much helpful.
