What is time on page and why does it matter for ad revenue?
How time on page is measured, why it is tricky, and how it relates to attention and ad value.
Written by Samhub with the help of AI·Updated 13 Oct 2026·3 min readTime on page is how long a reader stays on a page before leaving or moving on, often used as a sign of attention and reading.
How it is measured
Analytics tools measure time between events. Without an event at the end of a visit, the last page can be under-counted, so engaged time (time with the page active and in view) is more reliable.
Why it matters for ads
| Longer time | Effect |
|---|---|
| More viewable time | Ads are in view longer |
| More attention | Buyers value attention |
| Better data | Reading depth shows real interests |
