Can't get girls in clubs but can in bars/pubs?

I go to a student bar watching karaoke and i notice a few girls like checking me out for a prolonged period... like 3 of them. They were with friends sitting down so i didn't do anything. I didn't look at them first or anything so I'm pretty sure they wouldn't have a bad reason to look at me. But like whenever i go clubbing, god damn girls just are not interested, il try and make eye contact and they generally look away.
Confused as hell. I'm honestly not much into clubbing so it's not like a big blow, mind you the people i go out with generally don't go to pubs/bars, just clubbing but yeah.

It depends on the environment and how far you stick out. In clubs the guys are usually well dressed and attractive, so you will find more competition.

But in pubs it's mostly just a bunch of balding Viking look a likes with beer bellies.

How does making eye contact with a few girls count as ‘getting girls’?

I'm a girl and I'm not very good at the social side of things so whenever I go out I avoid making eye contact with anybody outside of my social circle, but that's just because i'm kinda awkward and I tend go out to spend time with friends not to hook up with someone. But there are some girls that become flustered when they make eye contact with the person they've spent all night checking out which could cause them to break their gaze.Personally, I find that when other people walk over and initiate some form of interaction I pay more of an interest in that person in comparison to someone who happened to glance at me a couple of times from across the bar. If the girl isn't interested or she's already in a commitment I'm sure she'd find a way of communicating it in a not so subtly way.

I totally get that, but this is often every girl at clubs. I will glance at them, they will look at me, then look away. I'm a 7/10 at best so I'm not going to make any girl flustered but i do sometimes out of nowhere have the odd girl show interest on the train or at student bars etc.

supply and demand.

The club is bigger, more packed, more males, more competition

more choice = more pickiness

A bar typically has less people so you get noticed more. Also generally womens shields are higher in clubs than bars/pubs as males are more aggressive in wanting to pull.

go to a small nightclub is my recomendation

Yeah i went to a small club and i had a lot more luck. I mean I feel like girls just wait until good enough guys come up to them in large clubs. I'm not really looking to pull tbh, actually more looking to date someone, of course clubbing isn't the best place but i'm limited given my current uni friends group.
