In a DigitalPoint Forums thread, a member asks how to check for an invalid PageRank. This is a timely question given that there was a PageRank update earlier this week. Since you can fake your PageRank, it's good to have the right tools on hand to verify PageRank.
Danny at Search Engine Land just wrote an incredible authoritative guide to PageRank and highlights some points that still need to be reiterated: PageRank really doesn't matter in the grand scheme of things and it is only one measure of "importance" for your site but isn't updated all too often and thus shouldn't be considered heavily.
Still, a bunch of tools were offered to check the PageRank of a site, and I will be linking to them below:
- Live PageRank: Checks your PageRank on all of Google's datacenters
- Verify PageRank: Checks your PageRank and verifies its legitimacy
- Fake PageRank Detection Tool: This one is currently not working, but the coder says he's trying to get it fixed so I'm linking to it in hopes that he will.
- Check Fake PageRank: This tool also checks your PageRank and verifies if it is valid.
How do you ensure that these tools are accurate? You can also do the easiest check:
Best way is to check manually on IP which shows updated PR.info:domain.com
If results are nothing or url(s) which doesn't match original then something is fishy if only 1 url is returned and its same then its 100% ok.
Discussion continues at DigitalPoint Forums.

I think the first tool is the best one, all the other three is not showing PR from various IPs... But anyway thanks for the list :) Pratheep

Does PR matter anymore. I think we should look page content not pr.

The "fake" PR thing shows everything is fake. My sites are all completely html. I couldn't fake a PR if I had to. They all show fake. NOT a good tool to be listing as accurate....

These "fake" PR checkers are not always correct but they do help a lot. I use http://www.digpagerank.com the most.
