Most likely, there are tons of blogs receiving more traffic than your primary Web site.  You can siphon some traffic from these sites with some etiquette and a simple technique. 

Most bloggers don't mind you promoting yourself a bit, as long as you provide value to his or her readership.  I certainly don't mind when readers leave this type of post on my blog. 

Use a 95/5 rule of providing only 5% self-promotion and the rest some comination of value-added content and compliments.  Here are the five steps to using other blog sites to drive traffic to yours.

1.  Read a recent blog post on a popular site.

2.  Compliment the blog host on his site and message. 

3.  Use an incidental credential to introduce your comment, such as "in my experience as a speaker" or "when I published my book on the subject" or "in my 15 years of experience." 

4)  Offer a value-added comment that will help readers. 

5)  Finally, give your contact information.  Note:  Some blogs automatically reject comments that contain full URLs.   

If you are too blatant about promoting yourself, it won't matter how valuble your comment is.  The comment will be disallowed. 

Play by the rules, be nice and you can use other peoples' blogs to drive traffic to your site.
