Lookaz.com - Your internet Guide

The most important factor to get a higher page rank in search engines is the number of other websites that link to yours. Of course nothing is this easy and only relevant websites that link to your will improve your website ranking. This means, if you own a dating website and and you have only gaming websites linking to yours, you won’t have such a high rank as if most backlinks came from dating websites. And the million dollar question is… “where can I find good places to link to my site.”
My advise is for you to look for this information in forums, like sitepoint or digitalforum. There are always lots of people looking for websites to exchange links and you’ll find great deals (free and paid) which will help you boost your website rank and if you know the importance of page ranks then you know that a higher PR means more traffic which means more sales.
