As far as I know artstation is most popular portfolio website out there.
Some stats here (https://www.similarweb.com/website/artstation.com).
So something in order of 15 million visits a month.
It is safe to say it has great global reach but different site analytics give it contradicting results as to where traffic is exactly coming from.
According to Alexa it gets most traffic from China but probably "similarweb" provides more representative figures?
It's hard to get correct perspective via these ranking website as they often largely contradict, but it can provide some average view.
Artstation is a great portfolio website and it provides a personal free website that you can customize to your own likes.
It is however relatively hard to get good position on Artstation as new work is coming in at a rate of around 15 a minute.
There are three main stages, stage one "Community picks" is the stage for most popular works that get past other two stages with great success (you could say this is hall of fame).
Stage two is the stage for "trending" this is a look at work that gets lots of attention from viewers in last (third)stage. This last stage is basically view on all new work coming in.
As I point out previously it gets new work at a rate of around 15 a minute (more in weekend) so after few hours your work is beyond normal viewing and beyond reach to potentially get in stage two (except when you can pull in traffic from somewhere ells that is).
Your new post basically needs views and likes at a rate of around 50 an hour (in first 3 hours)to get in stage two where it can pick up some more views. Stage two runs a bit slower, around two to three days to potentially pick up some more views and followers, after that it drops flat.
Possibly best one can do is post new work (top work).
Some try to hack the system and post same work again after a day or sow but the community is very sharp for that sort of things and you will get yelled out very rapidly or even get banned + your reputation gets damage.
You basically need to deliver top of the line work and deliver it preferably ones every week to get past the bell curve and get to stage one "the Community picks". Ones you are past the bell curve you get views and likes at exponential rate for longer time.
I'm far below this bell curve and so is 90% of artstation members, you basically need to deliver top work fast (things that get you lots of views or likes and most importantly followers).
Note; this all has only meaning if ranking in top 10 is your goal or get good exposure for means of market own products.
Getting in traffic from other places can help and participating (giving likes and comments) also helps to get some views and likes, but definitely not at a rate to get in top 10.
If you manage to get more followers on Artsation then it gets a bit more easy because when you post something new they will get notified (even by email) and then they usual immediately review it and rank it if they like it, so that can get you in stage two more often.
I know, it's a mad house, but you got to love it, however things can be a little frustrating at times when you just want some attention ;-p
Here is how it currently works for me, If I post something new it usually is just good enough to get me in the trending stage for two days and that gets me a total of around 200 views, 10 likes and around 4 new followers, then it falls flat because 10 meter of snow is on top of me, so going up is slow process.
But apart from that it's a wonderful place to hang out and discover amazing works and get inspired.
Also its one of best looking portfolio websites out there, so having your portfolio up there is great way to show off.
