Trackback linking is a method of site linking, initially created in 2002 by Ben and Mena Trott, that can help drive traffic to your blog or other website. Trackbacks are currently in use by more than 50 million blogs and news sites. It is one of the most powerful social marketing tools available.
If you have a list of blogs that you are following, you can create trackback links to your own site that will let the owners of the other blogs know that you are linking to them and encourage them to return the favor.
There are a number of trackback software applications available to simplify the process. Most major blogging providers include support for trackbacks, but there are also independent applications that you can download to help you find more trackbacks.
Suppose you find a blog post that you think would be of interest to your readers, instead of simply commenting on the post, you write about it on your own blog. Then use a trackback link to let the owner know you've recommended their post. When they read what you've written, they may make a comment on your site or their own and link back to you.
Once the network is fully operational, it can be a very powerful marketing tool. It works with other types of websites as well as blogs to create networks without requiring registrations or mailing lists. It eliminates the need to enter your personal information along the way. It also lets the search engines know about other sites that are linking to yours which will help increase your rankings.
