I really need some help.
First: Pagerank (PR):
My website has been showing a page ranking of 3 and just this morning, I found out that it has gone to 0 any reason why such a drastic change could have happened? My confusion about this is that early this year, it was showing a PR of 0 and 2 weeks later it jumped to 3 and this morning, its gone back to 0. Why such a drastic and massive change in PR?
Secondly: Google search result:
I have one of my keywords on page 1 but it only appears on google search result page 1 when I use "google.co.uk" and when I change to "Google.com" it is not even anywhere close to page 3. What could be the problem, should it not be that if you rank on page 1 of .co.uk you automatically rank on page 1 of the .com? Or is it altogether a different ball game? What do I do to ensure they it ranks on page 1 on both if ranking is different on either.
Please your usual professional advice is needed.

Kind regards
