Help me please I never have girl friend before

I like a girl I met on social media. We seem to like many of the same things, which is why I became interested in her. I’d like to get closer to her, but I don’t really know what to talk about.

I’ve tried starting conversations about things she might like, but she doesn’t reply very often. I’m not sure if I’m doing something wrong or if she just isn’t interested.

What would be a good way to talk to her and get to know her better without being annoying?
