301 redirect domain to page on another domain

[activitysuper]

Hi,

If I wanted to do a 301 permanent redirect on a domain to a page on another domain will this cause any problems?

Lets say I have 4 domains (all indexed with content), I decide to create a new domain with 4 pages, one for each domain.

I copy the content from the old domains to the relevant page on the new domain and set it live. At the same time as setting the new site live I do a 301 permanent redirect on the 4 domains to the relevant pages on the new domain.

What happens if Google indexes the new site before visiting the redirected domains, could this cause a duplicate content penalty?

Cheers

I think it would have some effect. How big that is I don't know.

I am sure a 301 to any page doesn't carry 100% of its worth to the new page. So I think that may be the case with each page.

However, if your getting clicks to your new site from 4 domains and all those visitors in the one place. Then maybe it would have a positive effect on the site.
