Link building is the process of increasing the amount of links that are going to a given website. There are many different techniques such as; article submissions, press releases, social bookmarking, blogging and directories. All of these techniques if used correctly can help increase your links, page rank and search engine results.

There are two types of link building those considered black-hat and those considered white-hat. A good SEO professional will keep up with which methods search engines are flagging as bad black-hat practices and which are acceptable. If you are looking to hire an SEO company you will want to ask them if they practice any black-hat SEO methods because if a company practices black-hat methods it could harm the trustability of your website.
