Shortly after G00gz rolled out the latest Pr update, I decided to look into something I had never done before. With a list of domains that had just expired, I decided to register a domain that had expired wiht PR4. the PR update had already affected all of my existing sites, so I was thinking it's completed, and if a domain has PR4 after that, its safe until at least the next update. But it appears...yesterday it went to PR0. The expired domain was aged and it had some nice backlinks. so my question becomes... if you are purchasing an expired domain with PR, is it just a matter of luck in regards to whether or not it will be stripped of its Pagerank soon thereafter? Or is there a way of knowing which are safe and which to avoid? Or is this just very common that after a domain expires it loses the pagerank. Thx for helping a noob out.
