I've been trying to optimize my site and I got it to PR5 ... But I want to get higher PR if possible ... Any idea where I should put in more work ? My traffic dropped in January, but I guess/hope it will come back next google update. Pls have a look at my site and let me know what u think, both about the layout, functionality and where you think I could do more SEO work ... http://www.articles.hotlib.com
The only way to improve your PR is to get / attract more high quality inbound links especially for PR5 upwards.
Increasing PR won't necessarily increase your traffic. Are you targetting the right terms? Are you targetting them properly. It's not just about PR you know
it's pretty hard to raise your PR if it's already that high. you'll need a lot of quality inbound links
I wouldn't optimize my site just to get higher PR. Focus on creating great content to your users and the links will come. My humble little blog just got a PR of 3 (it has been live since June 06), but I have very few links coming in and most of them are from directories. Yes, I linked like mad to the blog sections in those directories, but I also just write about stuff that I think might interest some people. I get dismal traffic, but I just keep writing and I link just to link. I write for other people, not the SEs.
Layout, functionality will not help your PR. It's easy to update from PR0 to PR4, but it's difficult to update from PR5 to PR7, so you'd better spend some money in buying PR6+ links.
Aswell as good content, make the site as useful as possible, two pages of text isnt the most attracting thing.
