What are they used for?
Anyone who wants more exposure to their current website would want to use this type of linking. All it means when you use back links is that you have links on other sites that lead people to your website. They might be on another website where they content is relevant to yours. Or perhaps you have embedded them into articles published on the Internet. You may also be linking from your blog. The idea is to bring more traffic from an off site to your website where you need the traffic. You may also include others on your site to return the favor. You can also outsource and hire a service to get them.
