The third most popular way to get backlinks is through article marketing. Article marketing is the act of writing articles related to your web site's topic and distributing them to article directories on the Internet. The advantage of article marketing is that you can use it to promote your web site to a large audience without using any SEO tricks or paid services. Article marketing is also popular because it can create new content to your website, which search engines love. In addition, it gives you a chance to improve your web site by reviewing your writing style and researching new information about your niche. There are many article directories on the Internet, but the most popular ones are EzineArticles (http://www.ezinearticles.com), GoArticles (http://www.goarticles.com) and ArticleDashboard (http://www.articledashboard.com/). There are many sources for getting backlinks to your website. You should pick one or more backlink sources and then write and submit articles to get backlinks to your website. It's important to remember that when you get links from external sources, you should always include a link back to your own web site in the HTML source of the external page.
