301 redirect??

Can I take a page on one domain, redirect it to another domains page, and keep all of the backlinks, authority, etc from the original page.

So
Page A on Site 1 gets redirected to Page A on Site 2

the content and purpose of the page would be the same, the niche would be the same, in fact if it is possible i will completely copy the page. The page will disappear on Site 1 and reappear on Site 2.

Thanks

There's more data required. Are you simply looking to change your domain name and move content or use 301 as a SEO booster?

With the little information you provided. Yes, you can 301 redirect it to a new domain to try and keep some of the link juice. I wouldn't juse 301 redirect everything. I would try build 301s to the relevant links on the new site.

With current information, I would say yes you can do it. Sounds like it's just moving a site from one domain to another in your case.

If you are simply adding the 301 redirect then you will need to submit the links to the webmaster for the ranking. From your query, you are adding the redirection from one site to another.

I built a landing page on Site 1 that is only superficially related to the Site 1 niche. I would like to put the page on its own domain. So I would create a second site for it. If I do this will I lose all of the link juice I have to the original landing page.
Is there a way to point all the link juice from the Site 1 landing page to the same landing page on Site 2.
Also, I will just take down the LP on Site 1 and put it up on Site 2. I won't alter its contents significantly. Would this effect me? Would it look like duplicate content?
