Write and Submit "How-to" Guides

There are a lot of "how to" websites online today. You can write an article about how to do something related to your website niche or industry and submit it to these sites. Be sure to list your website or websites as resources.
A few examples of these types of websites include eHow.com, Instructables.com and Wikihow.com.
Just remember, these websites do not work like regular article marketing. You may not be able to list your link in your author bio. You may have to sneak it into the resources section.
