See exactly how far visitors actually engage
Scroll depth, active time, and reading behavior — not vanity pageviews.
CRO9 measures real attention, not just pageviews. With one line of code it tracks how far each visitor scrolls, how long they are actively engaged versus idle, and when they switch tabs — so you know which content holds attention and which loses it.
What does CRO9 track for engagement & attention?
Scroll depth
Exact % of each page a visitor reaches (25/50/75/100 milestones + max).
Active vs idle time
Separates genuine engagement from a tab left open in the background.
Tab visibility
Detects when a visitor switches away and returns.
Engagement summary
A per-session rollup of attention across every page viewed.

Why does engagement & attention matter for conversions?
- Find the exact scroll depth where visitors drop off — usually right before your CTA.
- Prove which sections earn attention so you can move offers above the fold.
- Stop optimizing for pageviews that bounce in two seconds.

Frequently asked
Does it slow my site down?
No. The tracker is under 15KB gzipped and captures scroll and dwell passively with no impact on load.
How is active time different from time on page?
Active time excludes idle and backgrounded tabs, so a 10-minute abandoned tab does not count as 10 minutes of engagement.
Do I need to tag sections?
No manual tagging. Scroll and attention are captured automatically on every page.
