Heatmaps settle arguments that opinions cannot

Website redesigns are usually argued, not measured. Someone senior finds the page too long, someone else likes the old hero, and the version that ships is the one held by whoever spoke last.

A scroll map ends that conversation quickly, because it shows the exact percentage of visitors still present at each point down the page.

Reading a scroll map properly

Do not look for the bottom. Look for the cliff — the row where the number drops sharply. A gentle taper down the page is normal and healthy. A cliff means something specific broke attention: a wall of text, an image that looked like the end of the page, a section that answered a question nobody asked.

The fix is almost never "make the page shorter." It is "move the thing people came for above the cliff."

Click maps catch a different failure

Click maps show taps on things that are not links. It happens constantly: people tap product images expecting a gallery, tap a heading expecting it to expand, tap a phone number that was never made tappable on mobile.

Each of those is a visitor telling you what they expected the page to do. Cheap to fix, and you only find them by looking.

Then test it, do not just ship it

Once you have a hypothesis from the heatmap, run it as a split test rather than swapping the page over. Two reasons: you find out whether it actually helped, and you get a number to show the person who wanted it changed for a different reason.

Wait for significance before calling it. A 20% lift on 40 visitors is noise, and acting on noise is how sites get worse slowly.
