I never have much trust in the time on page or time on site numbers. In your screenshot, the number sure looks like it is meant to be a total.

I use Matomo for my analytics. I think their little Javascript doodad attempts to report back time information after 15 seconds. Anyone who clicks away before that timer goes off is recorded as a zero.

I get a sort of warm fuzzy feeling when I see high time on page numbers, but zeroes never bother me. There are a huge number of reasons why a time can't be captured, but when a time is captured, it is almost definitely someone who had eyeballs on your page.

You're doing a good job, Simon! I would be thrilled to see a million clicks from Twitter on one of my posts. I am just more excited about your 50k clicks from Hacker News!

> Time on Page

> The average time people spend on a particular page on your site. This is calculated as the difference between the point when a person lands on a particular page and when they move on to the next page.

Why in the world do they measure time on page like that? All they need to do is compare timestamps between hits...

There isn't always a second hit.
