Pick one or two pages on your website for long term targeting with Inbound Links.
It is called PageRank and not WebsiteRank because Google gives a rank to every page, not to every website. Yes, there is a connection between pages on a website, but there are many examples of widely varying PageRanks within pages on the very same website. This is important because when you create Inbound Links, targeting the highest value web pages will decrease the bounce rate (bounce rate means the % of visitors that follow a link to your website and leave after viewing the page they arrived at) be sure to target one or two specific pages for which you want to increase the Inbound Links count to.
For example: Your website has 12 pages, but two of them in particular are where you want to drive traffic to; the Products page and the Services page. You might also consider the homepage itself, but whichever pages you select for SEO targeting, make sure they are the best candidates for eventual arrival of visitors when they click a link somewhere on the web and come to your website.

It's all about giving value to the reader of your posting. Value, value, value.
The key is Value. Give valuable information to a forum, blog, bulletin board or other active community dealing in your subject and you have earned the right to add the link back to your site. The link rewards you in two ways (1) it increases your raw inbound link count determined by search engines and (2) it offers visitors the chance to click the link and come to your site. That second reward is more effecive when they like what they read in the posting you made, and they see a direct connection to the subject when they come to your site.
