I recently calved off a directory of my main site to form a separate site. The pages were redirected so that I wouldn't lose the search engine visitors as well as those from the many links to interior pages. Well, Google dropped the old site's pages on tuesday but does not show the same pages from the new site in the results yet, although they do show with the site search. While the new site does not show pr yet, the pages should have as much as before since the incoming links to the old pages are redirected to the corresponding new pages and because everything is now 1 click closer to the new main PR source (home page).
Anyone have experience on how long the time lag is between losing the old pages and gaining the new when using permanent redirects?
