noticed something interesting. I placed three links on my home page of a 7 year old PR4 well developed website. One was to a blog i run and the other 2 to domains for sites I'm going to develop.
The blog has a little bit of content (probably 20 articles/entries, fair bit of info per entry) and has a pr1. Domain registered march 2007.
The other 2 domains that have 8-10 lines on the home page basically saying we are developing a new site have a pr3. One domain was registered way back in 2002 but the other was also registered in march 2007.
I found it interesting that the sites with no content would have a PR3 and the blog with a reasonable amount as well as some additional natural links from elsewhere (a couple of reasonable links too) would only have a pr1.
All sites are on topic.
Can't be domain age as one of the other domains was registered the same month.
Now i know PR isn't the be all and end all but i found the difference peculiar.
