There are a few things you can do to talk to girls on Instagram if you want to be successful with the platform. First, make sure that your account is public and that you have a lot of followers. Second, be sure to use hashtags (#girlstuff, #relationshiptips) and post interesting or funny pictures or videos of yourself. Finally, make sure that your posts are relevant to the topic at hand and that you don’t just post pictures of yourself without any context.
