Google apparently has been doing another update of  the pagerank visible in  the toolbar. This appears to have been happening over the last couple of days. There are many reports of  people with dramatic drops in page rank happening on sites. I have one old site which I only just began reworking in the past week which has dropped considerably. However, the homepage of this site – BizRave has gone up from a PR 3 to PR4 on this update.  I have some other sites that don't appear to have yet changed up or down. I think things are still in motion, so who knows what will be the final changes. You can watch my video explaining visible pagerank at  http://www.bizrave.com/pagerank-exposed-video/  .

Many people believe that visible pagerank is not as good an indicator of  the importance of a webpage as used to be the case, at least in terms of ranking in the search results for specific pages. It has been my experience that pagerank is much less important that the number  of links and link text pointing to a particular page in influencing the search results.  Anyways, regardless of the importance on places on visible pagerank, there does appear to be an update happening which came much sooner than was the case last time.
