Link building refers to the technique used by websites to get other websites to place a URL link on their sites to attract more traffic. This also contributes to a large extent in increasing the visibility and rankings of the site. Building links is a continual process and includes communication, research and exchange of links as important facets. The simplest way to get links is through link exchanges, as they are mutually beneficial. Article writing and submission is also a very useful option and can spread content and links through the internet. These are among the more popular link building methods used.
