It is page rank checking website. http://www.checkpagerank.com But the question is what this website is earning? can this website earn ?
For fun? If you have other sites that make money, you can afford to do some just for fun. A kind of status-symbol: "look here, I know how to do this and I can afford to do it for free" -- also, if it's well received in the community (ie good PR, lots of links), you can always put a link to some of your other sites on there... Those are my ideas when I do a site like that.
I'm impressed with how quickly that site shows the page ranking...thanks for the find. They have an advertising space at the top for the future, and I'm sure it doesn't cost them too much to run that site. It looks like a nice, simple side site where maybe they'll get lucky and someone will want their advertisement displayed up top.
I personally use www.pagerank.net and http://www.seochat.com/seo-tools/future-pagerank/ to check my Pageranks.
i would agree with the first reply, i would make a site like that just for the fun of it, something to mess with and take my mind of things.
The advertisement space up top is via AdBrite, and if you follow the link, it goes to their AVNAds site, and shows the rates they're asking for checkpagerank.com. Over $50 for a 30-day text link. Since the space up top is blank, maybe advertisers aren't willing to pay that.
I just use the Firefox Google pagerank plugin. It saves me going to a specific website just to check the PR.
Probably just have other sites linking to it. They probably have a couple other bigger sites just link to it, to gain pagerank.
i feel such mite help get bit of traffic, i dont see them generating so much revenues, it can get some fame to site owner with lot of backlinks .
Very good Ranking in Alexa,But Page rank facility is provide by many more sites also.........I can't find any difference.
