I don’t use any sort of analytics on this blog. I don’t know how many people have (or more likely have not) read this post, or even visited this site.
And I do that for a purpose. If I saw the (likely) lack of engagement then it would be discouraging.
If no one is reading, then why write?
But that question is fundamentally wrong because if you don’t write then no one can read.
I’m not saying web analytics is a bad thing, it can be a powerful tool and can guide you in the right direction. But it shouldn’t be used to take you away from your mission.
