1. Website Traffic

How much traffic your blog receives is an absolute figure and one that can be measured fairly easily. Free tools such as StatCounter and Google Analytics are quick and easy to setup and will give you a good breakdown of how much traffic your blog receives as well as more detailed analysis.

Some may consider 10 visitors per day successful. For others, the threshold might be 100 or 1,000 or even more. It’s a personal thing and will depend on a blog’s niche and the blogger’s aspirations.

But what if we look deeper? What if we looked at measures like the number of page loads per visit or visit length. Maybe these measures would give us more insight into what our visitors think of our blog, and ultimately whether our blog is successful.
