Is this a sign my PR is improving?

I have a 4 month old site and my homepage has been at PR5 for the past month or two. My internal pages (around 30 - 40 pages that are indexed by Google) have been at PR4.

I've been working on inbound links and increasing my number of indexed internal pages and I just noticed that all my internal pages are now PR5 as well.

This seems like a indication that the PR of my homepage is increasing and it's passing to my other internal pages. Correct?

That could be the case, kawikadave. Earlier this month, there were reports of a broad range of sites that seemed to bump up a notch, too, so it could be some kind of algo thing.

It could be a good sign, or it could mean that before Google was simply guessing by assigning your sub pages one PR point less than the index. If I had to guess, however, I'd say it's a sign of your site improving in some way.

<-- Agrees with Jay. Looks like Google calculated the PR for your internal pages.
