You may or may not have noticed (probably you haven’t) that there is a tiny smiley at the end of each page on my blog. I was curious when I first noticed it, because I certainly haven’t put it there. After a little digging, I found this info on WordPress support pages. Here’s what it reads:
In order to tell you all the cool stats about how many visitors you’ve had, which of your posts are most popular, and how people get to your site, we need a way to track things.
We’re able to collect this information by loading a small image to your page when someone looks at it.
And we chose a small smiley 🙂
That’s it. Mystery solved. I wonder who decided to choose a smiley as an image. For example, they could have chosen a 1×1-pixel image which could have been virtually impossible to see. It is cute, after all.
