is backlink from noindex page gives a juice?

there are a lot of strong sites that allows to make a backlink from your profile page
so do google refers in someway those links to my site?

it is gives my site some "bonus" that it have backlinks from those strong sites?

i mean if i go to my site through the noindex page, though google is no read the page
he can still recognize that the visitor came from this site = it is logical that google will understand that the strong site gave me a backlink?

google analytics can see from which site comes the traffic or i wrong?

many giveaways of high da site have a lot of sites that the backlink is from the profile page with noindex tag
so it still worth to waste time and open a new profile from that site to get a backlink?

and sorry for the broken english

Why don't you make a case study on this.

I think it will be interesting for many to test that theory.

In my opinion, a noindex page is in case a forum comment or discussion board then it could pass link juice eventually only if you keep on getting referral traffic from those pages.

As far as profiles, there are no chance someone will visit your site using your profile link unless that link is from a social networking platform which usually indexes our profile so it already passes link juice.. So it's rare to get link juice from noindex page.

Yeah, i agree to your point that if someone is visiting your site by reffering a link on noindex page then google will keep an eye on it and will eventually assign some metrics to those no index pages. But, still as I said, it's rare event that occurs.

In the case of no index page that does not refer any traffic (for example some profile pages that no one sees), it is worthless in terms of backlink juice.
However, it does have some traffic, there is a possibility you will gain some 'trust' factor value.
