social media marketing offers many ways to generate these links for little or no cost – articles, social media sites and blogs are just a few examples. Social bookmarking is another.
With bookmarking, you save bookmarks to blog posts, articles and web pages (including your own). You tag them with a “keyword” of your own choosing (preferably related to your business). You can then add a “tag cloud” to your website. The tag cloud contains the tags you have created and directs users to the bookmarks you have saved for that tag.
