Ive done some experiments over the past month or two about expiring domains with PR to see if it is worth your while to find these expired and wiped domains.
My idea why I would want to use expired domains may be the notion that old domains are favored than new domains, and to get immediate PR.
So I set out to find deleted areas with PR that I can enroll. One characteristic of domains I was trying to find was that the site still had a, and it was still shown in google. Get extra info on a related portfolio by visiting linklicious discount discussion.
I will not be mentioning the particular domains here as I need to control the results and stop people from building backlinks to these domains.
I registered about 4 areas, some have PR2 and PR3. Some have a few pages indexed, some have a few thousand. I also bought a couple of new areas for my new projects.
I found out that google seldom trips these domains so I need to perfect it but with some new backlinks. After creating some backlinks to these domains, two domains eventually lost their PR. These two areas have only a few pages indexed in google. If you have an opinion about data, you will seemingly wish to study about linklicious works. In one single site, I did so a 301 permanent redirect to the newest index page. Its PR was retained by this domain. One important big difference this domain has compared to the other two is that this domain has 1000s of pages listed in google.
In still another domain, I did so a 301 and direct it to a fresh new domain. The result is that the new domain got indexed faster and more pages were indexed compared to another new domain I listed at the same time frame. But, PR was down to 0.
There is also an incident where I did so a 301 direct from a classic deleted area with PR and never got any benefit from it.
In summary, there is still inconsistent results on whether getting deleted/expired domains. Some works, some don't. However, what seem to work is that
a. Traffic does be contained by old delete domains from existing backlinks. If the old domain has tons of backlinks, it still does generate some traffic.
