Do facebook shares of deep links help the whole domain rank better?

[adriandg]

What i mean by this is if we were to obtain 10-20 facebook shares for 10 different deep links like these:

http://domain.com/deep-page/page-one
http://domain.com/deep-page/page-two
http://domain.com/deep-page/page-three
http://domain.com/deep-page/page-four
...

Would that help any of these rank better:
http://domain.com
http://domain.com/product1
http://domain.com/product2
etc...

Extrapolating, does the same count for Twitter, Google+, etc?

Yes any value the link give is spread around the site, but of cause the first page gets the most

Social signals, and FB shares especially, have a strong correlation with rankings; therefore to have FB shares of internal links is surely useful. But not enough! Then, just one share surely is not going to make a real difference, therefore craft those product pages so cool that it is not possible to desire to share them. A good way to improve FB shares is to integrate your site with the FB open graph and let people sign in in the site with FB connect and comment your products with FB comments.
