Two websites to merge into one - one has already been migrated - what about the second?

Hiya Mozzers,

I have just been checking a website for duplication issues (this is a new website - they have just migrated across from old website to this new "main website"), and I found a wordpress blog on a different URL, duplicating the "main website"'s blog.

Should I just close down this wordpress blog, 301 redirecting from the wordpress blog to the "main website"'s blog (equivalent blog posts to equivalent blog posts, with other indexed non-specific pages 301 redirected to "main website"'s blog homepage)?

Thanks in advance for your help.

Hi Luke,

Redirect the old blog to the new blog.

I would forward that old domain to the new one at the DNS level (no domain mapping) as a 301 redirect. Then you should be able to safely shut down that old blog, since you said "duplicated" content.

But if the old blog URL structure is different than the new main site, and you have a significant number of links to that old Wordpress site, you might want to set up server side redirects to preserve any link juice coming from those inbound links.
