Domain Forwarding / Multiple Domain Names / or Rebuild Blogs on them

[WindshieldGuy-276221]

I am considering forwarding 3 very aged and valuable domain names to my main site. There were once over 100 blog posts on each blog and each one has a page authority of 45 and domain authority of 37.

My question is should i put up three blogs on the  domains and link them to my site or should i just forward the domains to my main site? Which will provide me with more value.

I have the capability to have some one blog on them every day. However, i do not have access to any of the old blog posts. I guess i could scrape it of archive.org. Any advice would be appreciated.

I think there are 2 ways to do it.

(Quick version) redirect all pages from your old domains to the new domain, however if you have links with specific keywords pointing to old posts, all the weight will be transfered to your new home page and most likely the content will be far different from the original post, and you might loose some positions you used to have on some posts.

(Long version) scrape all the old articles, put them on your new server, then redirect each article independently from your old site to the new site.

ie: redirect from www.myoldsite.com/article123 to www.mynewsite.com/article445

This way you keep all valuable links pointing to these post, but also the context of each link will match the content of the page like nothing happened (if you have such link of course).

I am no expert in blogs, but I did the long version with our online store for each products and it worked like a charm. I kept the contextual links, pagerank and position for each one of them.
