Two or three days ago Google exported the current Pagerank values to the Google toolbar. I always find this interesting - not because I put a huge amount of faith in a higher Pagerank value, but simply because I take a higher Pagerank value to mean I'm probably doing something right in terms of SEO.
This time round I had some confusing results. On the main SliQTools website, 6 inner pages moved from PR2 to PR3 but one page dropped from PR2 to PR0. The homepage itself remained at PR3 while another page (relatively new) that does really well in SERPS for certain keywords had PR 0. I find it a bit hard to explain how so many pages are PR3 and the homepage is only PR3 and why other pages are PR0 but still do well in SERPs. I guess Pagerank isn't as important as it used to be.
The other confusing aspect about the recent export, is that another of my websites has gained PR2 from PR0. This is hard to explain since it only has links from a forum. Its inner pages are PR1 even though one of them is virtually blank.
I collaborate on another blog with a friend. This blog is still PR0 but he has a new website - registered less than 2 months ago that only has links from the PR0 blog - and the new site has a PR of 1 which is higher than the only external site giving incoming links.
