Why would the PageRank for all of our websites show the same?

[Alex-Harford]

The last time I checked (early this year), the PageRank on the sites I manage varied, with the highest showing as 6. It made sense as the PR6 site has loads of links and has been around for a long time, whereas the other sites hadn't.

Now all of our websites are showing the same PageRank - 6, even one that has recently launched and another that has barely any links/traffic or anything to it. I didn't check the PR of that one last time (I'd be surprised if it was 2), but the sites now showing as 6 ranged from PR3 to PR6 back then.

We changed server in February...so could this issue be something to do with all of the sites being stored on the same server? It doesn't seem right but it's the only thing I can think of.

At the moment, the Domain Authority for these six websites ranges from 27 to 62.

The server shouldn't be an issue at all. PR in the tool bar is very unreliable. Soon Google is going to stop supporting it. I wouldn't worry at all about it. Domain authority and page authority from the SEOmoz tool are much more reliable.

I don't use Google Toolbar, I've used the PR checker on here, and tried a couple of others elsewhere, including prchecker.com I think. Do they all use the same data?

[JoeAmadon]

Yes. Every tool I know of that provides PR pulls from the tool bar PR.
