Equally important is your actual website content. It must be information that people can use and take an active interest in. Having content that matches your keywords, should also be obvious.
Why is this important?
PageRank is 
extremely important that it determines how high you get on search engine results. And just as it is useful to have incoming links are from reputable, reliable, relevant sites, your outbound links will also be more valuable to the pages you link out to. This is important when negotiating link exchanges with other sites. The higher your page rank, the more desirable a link from your page will be to others - even those willing to pay for these links.
Are there ways to improve PageRank for free?
Absolutely! To follow are some of the simplest things you can take.
Build more pages: The more pages on your site, the more content, it is generally considered to have. If your site has only 3 sides, the maximum page rank would be a 3rd Make sure you have at least 8 relevant pages including the main page to have a healthy amount of content.
Avoid Blind Links: Let's say you've worked really hard to get 8 good pages. Your page rank ideally have the potential to become a page rank of 8 But if half of the pages, not flying anywhere, you have a problem. When search engines "crawl" your site, they want to go from one page to another. You can have a really good side but if it does not have any other link it to go somewhere new, it will be seen as the spider to be a dead end page, which will hurt your site's PageRank. Make sure that each side has a door out, other than a back button (which the bots will generate the equivalent of a good old "Nothing more to see here" type of statement). Combat this by making sure you have at least a link back to the index - or even better a site navigator at the bottom of each page with a choice between the main pages of your site (i.e., FAQ, About us, contact us, etc) . Again, these are pages that add comfort to your human visitors as well.
Create Internal Links: Remember to make links to yourself when appropriate. For example, does your About Us page, not just mention your online ordering system - hyperlink to the page where your visitors will need to go to begin a warrant. Not only are you creating another link to the crawler, you also make it convenient for your guests to find that page right then and there if they wish.
Take advantage of Free Directory Listings: They may not always be large, high ranking sites, but they are an easy way to get your name out there. You never know when someone may end up using one, and thus find yourself in the most unexpected ways!
How to make more of the cost: Getting a high ranking site to link to you is not always the easiest thing to do. Sometimes it is necessary to buy that privilege via ads. There are literally 100's of different opportunities to choose from, but the most effective way these days is to buy text-based links to your site.
