Help with 301 redirects.

[Davit1985]

Hi,

I would like to say thank you in advance to all who help me with my question.

MOZ crawl test showed duplicate content for a site that i just finished. I have www.site.com, site.com and site.index.html( all are the home page) So i have decided to 301 redirect all pages to site.com. And I also learned that when you do a 301 redirect all link juice is passed to the page that i redirect to. Here is my question: If someone links to my site using www.site.com instead of site.com in the future, will the 301 redirect still pass the pr to the page?( site.com). Or it only does,  at the time of redirect and not in the future. I know this might be a stupid question but i am really new to this and couldn't find an answer for that.

Thanks guys

When you 301 redirect www.site.com to site.com, as long as the redirect is in place, the "link juice" will be passed from www.site.com to site.com. [And as the saying goes, there are no stupid questions...]

When you 301 Page A To Page B.

For Google bot now b is new a.

All links(past + future) of A ======> B

Because B is new A.

In other words, future links of Page A pass link juice to Page B.
