Hi, Robert-
Small multiple-redirects should not pose a problem to Googlebot as
long as it can fetch each page along the path (i.e. no robots.txt
exclusions, 404's, etc.). However, for this kind of permanent change,
do make sure that you're using 301 redirects to let us know that the
old URLs will not be coming back soon.
As with any large site restructuring, there may be some ranking
fluctuations as your url changes propagate through our systems.
However, after Googlebot has a chance to crawl of your old URLs (and
get 301-redirected to your new pages), it should be appropriately
passing PageRank and other signals on to the new pages. This process
might take just a little longer for double-redirected URLs than it
would for single-redirected URLs, but you might not even notice a
significant diafference between this and other URL restructurings that
you've set up.
But, as is often the case, JLH is here to provide sane, careful
advice. If you want to see how bad the URL-restructuring hiccough
will be--and if you can up a section of your site without affecting
the rest--you will be able to better weigh the costs and benefits of
making the change. Then you can come back here and speak with the
voice of experience, just like JLH. ;-)
Hope that helps!
