I'm having my own site. I've checked its page rank and it is shown 4 (some pages are having 3) from all the datacentres of Google, and many other websites.
But I'm afraid to see "Suspicious Page Rank" comments in lots of websites, while checking the page rank. Some are saying, "We cannot determine the page rank of this site", though all of them are showing PR 4 at the same time in results.
What does it implies. Can any SEO expert check this and tell me the reason. I'll be glad to to know some suggestions to resolve this problem.
