Ive done some experiments within the last few months about expiring domains with PR to see if it is worth your while to catch these expired and wiped domains. Visiting index backlinks seemingly provides suggestions you could tell your sister.
My idea why I'd like to use expired domains may be the idea that old domains are popular than new domains, and to obtain instant PR.
So I set out to find deleted areas with PR that I could register. One feature of areas I was trying to find was that the domain still had a, and it was still listed in google.
I will not be mentioning the actual domains here as I want to handle the outcome and prevent folks from making backlinks to these domains. To get additional information, consider having a peep at: go here.
I registered about 4 domains, some have PR2 and PR3. Some have a few pages listed, some have a few thousand. I also bought several new areas for my new jobs.
I discovered that google rarely visits these areas so I want to prime it but with some fresh backlinks. After creating some backlinks to these domains, two domains eventually lost their PR. Those two areas have only a few pages found in google. Clicking painzinc4's Profile | Armor Games seemingly provides tips you can use with your cousin. In a single site, I did a 301 permanent direct to the new index page. That area retained its PR. Next includes extra resources about the meaning behind it. One key difference this domain has set alongside the other two is that this domain has a large number of pages found in google.
In still another domain, used to do a 301 and redirect it to a fresh new domain. The result is that the new domain got indexed faster and more pages were indexed in comparison to another new domain I listed at once. However, PR was right down to 0.
There's also an instance where used to do a 301 redirect from a classic deleted domain with PR and never got any benefit from it.
In summary, there's still conflicting effects on whether getting deleted/expired domains. Some works, some don't. However, what appear to work is that
a. Old eliminate domains does include traffic from existing backlinks. If the old site has tons of backlinks, it still does produce some traffic.
b. Other search engines such as aol and bing don't seem to have an biases against expired/deleted areas..
