Please use that sarcastic tone some where else Keri. And I'm not asking for the algorithm.

I guess its me that has asked the question in a wrong way, I apologize for that. Let's take Google out of the picture completely for the most important question.

Is there ANYONE in the whole wide world that in some way can see if a domain has been expired and then been bought again just seconds later? If yes, HOW?

The next question would then be why Google doesn't just put the PR back to 0 and "block" all the linkvalue that the domain name had before it expired. Because its not very likely that its the same owner that buys the domain after it has expired (the domain doesn't just expire immediately, its sits in a quarantine for a few months). But as I said, don't ask yourself that yet, answer the first question.

Is there any technical yoda in here?

Thanks for the answers but I'm afraid that doesn't answer the question. How does it work technically?

Hi everyone

I’ve been doing an experiment during more than 1 year to try to see if its possible to buy expired domains.

I know its considered black hat, but like I said, I wanted to experiment, that is what SEO is about.

What I did was to buy domains that just expired, immediately added content on a WP setup, filled it with relevant content to the expired domain and then started building links to other relevant sites from these domains.( Here is a pretty good post on how to do, and I did it in a similar way. http://searchenginewatch.com/article/2297718/How-to-Build-Links-Using-Expired-Domains )

This is nothing new and SEO:s has been doing it for along time.

There is a lot of rumors around the SEO world that the domains becomes worthless after they expire. But after trying it out during more than 1 year and with about 50 different expired domains I can conclude that it DOES work, 100% of the time.

Some of the domains are of course better than others, but I cannot see any signs of the expired domains or the sites i link to has been punished by Google. The sites im liking to ranks great ONLY with those links

So to the question:

WHY does Google allow this? They should be able to see that a domain has been expired right? And if its expired, why dont they just “delete” all the links to that domain after the expiry date? Google is well aware of this problem so what is stopping them?

Is there any one here that know how this works technically?
