What's the best way to build backlink to be counted or credited by Search engine?

Hello,

Even though I created backlinks to my web site, not all the backlinks are counted (according to google webmaster or other backlink checking services).
People leave several backlinks in a article, blog, comment, forum post or other web pages but, some of them are never counted. Although you put nice article on a site, Google ignore the site. Sometime you pay link building service to build links, you see only very few of them are counted.
Sometimes, it's wast of time, money and effort.

How can we avoid it as much as possible?
