Buying up old domains, high PR, to absorb backlinks and authority?

[CareerBliss]

I'm thinking about purchasing http://employeesurveyresource.com/ .. $300

It's showing a PR5, but I'm not seeing many backlinks in Y! site explorer or open site explorer.

Has anyone been successful in absorbing the PR from older domains / domains without current content?

I know sometimes people can fake PR by 301'ing from a high PR site, to sell the domain and then cancel the 301, leaving you with a dud.

Can someone shed some light on this please? Thank you!

You should do some research into doorway pages. What you are talking about is a bad, black hat SEO technique. Doorway pages are domains you buy up and then redirect to your main site. It's a form of buying links and PageRank when you think about it.

If you see an expired domain with high PR and buy it up, that's fine. What is not cool is when Google has a full website in its index for a given domain and then the next day every URL of that domains 301's to the home page of some other domain. You don't want to get caught up in it, check out Google guidelines on doorway pages.

I'm not a guru, but it would probably be much better to build a Wordpress blog on those aged domains, create regular content and then link it back to your main site, not just regular 301 as you plan doing.
