I've been going on a bunch of tinder dates lately at they always end the same way. I get a kiss at the end of the night and nothing more. What are some things I should be doing to have a better chance of closing?

To give context, I am 24 and the girls I am taking out are the same age, give or take a few years. The dates consist of going to bar or gastropub for a few drinks and usually last around 2 hours. From there I drive them home and walk them to their door, that's when I go for the kiss. Have never been rejected for a kiss, but at the same time never invited inside. I have asked if they want to invite me in a couple times, but they always say next time. It seems that all these girls are looking for a relationship instead of a one night stand. Not sure if its just how it is or I am presenting myself in the wrong way. Any advise helps!
