SEO Tip: Free backlink from Twitter. Backlinks (or back-links) are the incoming links to a web site or web page. Backlinks play an important role in the popularity of a web site. Building backlinks is crucial for search engine optimization (SEO), and is a long and difficult process. Backlinks from important web sites have more value. Most web sites add "nofollow" tag to their external links, including Twitter. This makes linking from those pages less interesting in terms of SEO because "nofollow" links are not counted by most search engines. But there may be a way to get a backlink from Twitter after all. Placing an URL in the "Bio" section of your Twitter profile will make a valid backlink from Twitter, since this link will not get tagged with "nofollow". Select "Settings" and put the URL in "One Line Bio". http://moneybites.com/get-a-free-backlink-from-twitter
