Why don't girls on tinder respond to me?

If you matched on tinder then doesn't that already mean they are physically attracted to you. So what I don't understand is why don't girls respond when I message them. I try to never just say hi or hey or anything like that. I like to base it off something from there bio, but I get nothing. No one message back and its irritating, depressing, and just doesn't make sense why its so frequent. I know some probably don't check on theirs that much which I get, but it can't be all of them.
