Here’s a nice video on how to install Google Analytics on your WordPress Blog.
I tried a plugin when I started with WordPress. I don’t remember which one, but I remember that I had a small problem and decided to copy/paste the code myself.
On that note, I find my template is a little quirky, so I had to go into directly into the file to paste the code. The “editor” doesn’t get along with my template 🙁
