I know lots of webmasters and SEO gurus that say that PR (google pageRank - the little green bar on the google toolbar) is not worth that much but everyone is using it as a measure.
Webmasters refuse to exchange links with you if they think your PR is inferior to their website's PR. Lots of programs (reviewme.com ...) could reject your site because of low PR, some directory owners display the list of sites ordered with PR.
So ... here is some simple steps you can follow to get your sites PR higher than it is and maybe get some extra traffic while you are at it.
- Post your link in forums using signatures and/or places that allow website reviews, put the site url in the signature with your target keywords for titles
- Submit to free and/or paid directories (in general the younger the directory the easier would be to get accept it in it)
- If you have other sites put sitewide links pointing to your new website. If sites are totally unrelated subject, put the links in the footer with small letter (the link still counts).
- Put your link anywhere you can, without becoming a spammer (everyone hates spammers)
- Find some high PR sites and pay for a link if you have to. There is lots of projects on the internet that accept donations as low as $50 and they put your link in a high PR page. For example moddle donations page has a PR of 6 http://moodle.org/donations/.
- Using your link in comment posts. This won't necessarily increase your PR but it could give you a few visitors if nothing else.
For the record world experts net has been almost abandoned, unfortunatelly due to lots of things in my head and currently looking for ways to rebuild it into something new.
So no matter what some say, PR is in our lives and its worth something. I can describe it better with a metaphor, you don't need an Armani Suit but if you wear one people look at you differently. But, PR by itself is not going to get any money for your site, but having it will help get some extra attention, or better deals.
