Secret # 2
Utilize crosslinking and give references
Posts like standard articles are only as good as their sources. When you provide opinions, news or instruction in your posts, naming the sources which helped you draw your conclusions or provide new information to your readers gives your writing greater credibility. For example, one of my favorite blogging resources is Darren Rowse's Problogger.net. He discusses how to utilize crosslinking to promote blogs and build readership in his Blogging for Beginners series.
