When I changed the web theme of this Blog, my rankings fell for approximately 1 month however now they have rebuilt.This again can have the same affects on PR, however PR is generally affected by changes in the URL, so a redirect is necessary.

Google usually updates every 3 months, however within the past 9 months Google has been a little less “on time” so to speak, changing the predicted times that they update. I would expect another update most definitely in the next 2 months.

Thank you for your comments.

@Charles, this happens a lot don’t get too annoyed by the pagerank drop. As I have stated in many other articles pageranks importance has never been a big one altough there is a lot of fuss over pagerank throughout the years. Most of this attention comes from new players to Internet marketing and others who use pagerank to indicate a link selling price for their particular blog.
Keep writing, selling and be productive.

@Jeet your exactly right, I am guessing most of the more professional and well respected bookmarking sites and directories have some sort of automatic tool to do this for them though. Hopefully.

@Ajay it can take some time, something you might want to consider is whether your website or webpage has been available to Google for long enough to be ranked. You will find many pages of this site still with an N/A tag as Google has not got round to ranking the page yet.

@Vincent Its a good sign if your site is starting to get internal pages ranked this means your link structure may be working or the page in question has had considerably more attention compared to others.

Pagerank has lost its importance like I have talked about in other articles. Your exactly right many ad sellers depend on PR they are about the only people that do.

But then, PR doesn’t really matter these days, unless you are depending on it to sell ad space.
