Page rank inconsistency...

I have about 30 sites. When I find a bulk pagerank checker and put in a bunch of them, everything comes up PR0.

However, many of the sites do have pagerank, and when I use a different PR checker that has you input one URL at a time, the pagerank shows. Why might this be going on?

It would take so long to check each site individually...is there a working bulk PR checker?

 

I think you need to try a few more bulk page rank checker tools!!

Here's one:

there must of loads more, have a look in Google.

 

The PR check tools are not the valid ones. It may give wrong values too. So just compare the values with diffeent PR checking tools.

 

Obviously it's the PR checker fault. Just try out using another tool and find out which is the best to use.

 

Try some other tool like Iwebtool.com

 

Check with google toolbar will give you the exact page rank, all others some time will not give exactly and also its very simple just one browsing. But regarding back link better be away from google bcz not geting the correct and accurate

 

If you want to get accurate PR of your site, you have to use Google toolbar. Checking 30 site may not takes much time. Good luck

 

If you are using an automated PR checking software, then your IP might becomes blocked by Google for a while to prevent automated queries of the PR values.

My advice is to switch to another tool

 

Reason for inconsistency: The PR of your sites is not updated at all the google datacenters, that's why it shows different PRs at different times.

Use this free PR checker tool to check your PR at different datacenters

To check all your domain PR in bulk, you can use this multidomain PR checker.

 

Please be reminded that some too is not always accurate.

 

surely the tools being using are not working properly.

 

It is not gives accurate results, you can check better to manual.
