Hey Brian - One great tip is to make a list of your top 5-10 competitor's sites and find out where they are getting traffic so you can do the same for your site.

Check out the example below:

Step 1: Go to Google and with your domain search for similar domains:

https://www.google.com/?gws_rd=ssl#q=related:drivingtests101.com/+drivingtests101.com

Step 2: The first competitor site I see is (driving-tests.org) so I would make note of that domain.

Step 3. Go to Alexa.com and check the first domain (driving-tests.org):

http://www.alexa.com/siteinfo/driving-tests.org

Step 4. What you want to do is scroll down to the section that says "What sites link to (driving-tests.org)?"

Step 5. Make a list of the referring pages IE:

https://answers.yahoo.com/question/index?qid=20110126160933AAOseUU
http://www.pinterest.com/drivingtests/
http://usedcars.about.com/od/gettingstarted/fl/What-It-Costs-a-Teen-To-Own-a-Used-Car.htm

Step 6. Repeat for the other competitor's domains.

This will give you a good idea of where each of your competitors are getting incoming links and traffic from.

Once you make a list of the URLs - see how you could duplicate what your competitors did to get those links. Typically this will involve answering related questions asked by others or emailing a site's Webmaster or the author of an article, etc.

This requires a little work but in the end you'll not just get traffic but you'll get qualified targeted customers over to your site that will convert and help you grow your business.

Hope that helps!

Take Care,
