The content most shoppers never see
You spent real effort on your product description, your reviews section, your reassurance copy. Then scroll depth data shows that 60% of visitors stop scrolling halfway down — meaning more than half of them never see any of it. That’s the most common and most fixable finding in all of behavioral analytics.
How scroll depth is measured
Scroll depth tracks the furthest point each visitor reaches on a page, then aggregates it. A scroll map visualises this as a color gradient: bright at the top where everyone sees, fading to cold where only the most engaged shoppers reach. The point where the color drops off sharply is your “attention cliff.”

Share of visitors who reach each scroll depth
Illustrative scroll-depth distribution for a typical product page. Notice how few visitors reach the bottom — anything below ~50% depth is invisible to most shoppers.
What to do with the data
- Find the cliff on each key template. Home, collection, and product pages each have their own.
- Move high-value content above it. CTA, rating summary, and key proof should sit where the majority actually reach.
- Tighten the sections causing drop-off. If shoppers consistently stop at a long block of copy, shorten it or break it up.
- Check mobile separately. The mobile fold is shorter, so the cliff is higher up — content that’s above the fold on desktop may be buried on mobile.
- Re-measure. After changes, confirm more visitors now reach your key elements.
Pair scroll depth with the why
Scroll depth tells you where attention dies, but not always why. Pair it with a session replay to see what happened just before shoppers stopped — a confusing section, a slow-loading element, or simply content that didn’t hold interest. Together they turn a flat number into a clear fix.
The bottom line
Placement is one of the highest-leverage changes in CRO, and scroll depth is how you get it right. Move your most persuasive content above the cliff, and you put your best argument in front of every shopper instead of just the patient few. DynoWeb folds scroll depth into its AI fix suggestions so the placement fix comes ready to ship.
