low investment response

I'm getting more and more matches and responses from women but struggling on how to build investment from her. currently, im talking to women with empty bio who are 6/10 (gotta start somewhere) . example of response is get are 'yh', 'nope' and 'nothing much'

i realise that i was making the mistake of applying tinder game to instagram, and that was not working very well but since i made a few changes its been going well. so now just struggling with shitty responses on the first few messages i send.
