More than one person (Ben Gordon and Mike Fox, for starters) have asked the question of how I measure/track the blog.
Let me start by offering this...
RSS is the KEYThe single most important measure of blog success is "how many people have subscribed to your RSS/email feed?"
These are people who are giving you permission and attention to be a part of their lives. That's the best.
For RSS (here's my feed), I use www.feedburner.com It's got good tracking and a bunch of other options as well.
Next comes analyzing the pages...When it comes to page views, I take reports with a grain of salt, so I tend to use multiple reports to "triangulate on the truth."
Lastly, measuring activityComments are the key
I like to watch which posts (and what genre) generate the most comments from my "audience." This gives me an idea of where customer interest lies. Though, you need to be careful of the 1 percent rule.
If you are a popular blog/person, you can use TweetScan to monitor traffic about you. Pretty nifty.
And a word on Publicizing...
And as far as getting the word out goes..
