How often do you check your page rank?

When I hear that there has been a page rank update, then I will go check it but not before. It only changes during the update. So no reason to check before.

I am quite unique in my answer as compared to the above ones as I do check the PR of my pages almost daily. Its not because I am much concerned of it but because it's a part of the plugin of the browser.

Why is there a need to check daily? As PardyCo stated, PageRank doesn't change everyday and if it does, it's on a span of 3-6 months. No one knows the exact date of the update. Besides, PR doesn't really help you in getting traffic.

Being active on Facebook and other sites (as I'm sure you are) is probably very helpful for getting traffic to your site. More so than page rank.

I check it once a week. Sometimes I feel really bad and foolish, as I know pr change every 3 months or so. Still I check it every week :|

Maybe the PR of your site is a point of pride and knowing your page rank has increased helps you do a better job of site management as you are more proud of the site when it performs well.

I usually check after learning that its been updated. More frequently i check alexa rank.

Page Rank updates daily, you only get the new official number to be seen every 3 months. PR is a SEO factor, especially for quality of backlinks.
If PR itself would be updated every 3 months, rankings would often rise up or fall down drastically. But nothing unusual happens on PR update day.

rarely, when Google release page rank update

And how do know when did google updated it's pr ?

I do thought PageRank and SEO is not directly connected to each other?

Yeah that. Everywhere IM forum you visit on the PR update day, there are threads like "Why my PR dropped down" and "Wow, I just got PR2, it's awesome"

I only get to know it when webmasters started posting their new PageRanks.

This is correct. A lot of people (and this thread proves it) try to check their PR constantly. The problem with this is, Google only updates the PR every once in a while (3-6 months).

I my self actually never do check them. Even when updates do occur. I personally don't feel that Page Rank has any effect on me or my sites. I have seen so many Page Rank get faked to try to either sell the domain, or sell advertisements on them. And yes, you can fake your PR.

I was just recently selling a website in which the domain had a small PR. The buyer constantly wanted to lower the price purely on that fact. I had told him I was not doing it because I'm not selling the site for its PR. The site would have made that money in 2.5 months for the price he was asking.

So again, I never check it. In my own opinion, PR has no value to me.
