A scrollmap is a visual analytics tool that shows how far visitors scroll down a webpage. Also known as a scroll heatmap, it identifies where users stop reading or navigating. Marketers use this data to place calls-to-action (CTAs) and critical information where the most people will see them.
What is a Scrollmap?
A scrollmap provides a visual representation of scrolling behavior using a color-coded gradient overlay. This tool tracks the vertical movement of visitors to identify which sections of a page are "hot" or "cold."
The colors typically follow a specific logic: * Red or White: These areas are the "whitest-hot" and represent the regions where the majority of people scroll. * Yellow and Green: These zones mark where user engagement begins to decline. * Blue: These "cold" zones indicate elements that users do not engage with or reach.
By visualizing the average depth of on-page scrolling, you can find the ideal length for a page and determine if users are seeing your most important content.
Why Scrollmap matters
Scrollmaps help teams stop guessing about how users navigate a layout. They provide raw data to support design and content hierarchy decisions.
- Locate the "Average Fold": It identifies the cut-off point where content ends and scrolling begins across different devices.
- Identify Drop-off Points: You can see exactly where visitors lose interest or leave the page.
- Spot "False Bottoms": A scrollmap reveals areas where layout issues make users think they have reached the end of the page when more content exists.
- Optimize CTA Placement: It shows the sweet spot that most visiting eyeballs reach, which is the ideal location for a button or form.
- Improve Mobile Experience: Long landing pages can kill mobile conversions; scrollmaps reveal exactly how much content mobile users are willing to consume.
- Prioritize Content: You can learn how to move critical information higher in the hierarchy based on real engagement levels.
How Scrollmap works
Most tools generate scrollmaps automatically once tracking is active. The software detects the page in view and calculates the maximum scroll depth for all visitors.
- Data Collection: The tool tracks the vertical position of every visitor's scroll bar.
- Aggregation: It combines the data from all users to find patterns.
- Visualization: It overlays a color gradient on your webpage.
- Fold Calculation: The system automatically calculates the average fold line for both desktop and mobile users.
- Depth Testing: You can place markers at any point on the page to see the exact percentage of visitors who reached that depth.
Best practices
- Move CTAs to hot zones: Use the data to place your most important sign-up buttons or forms in the red or orange sections.
- Trim the fluff: If attention drops halfway through a blog post or landing page, tighten the message or remove unnecessary sections.
- Audit for different devices: Compare desktop and mobile scrollmaps daily. Mobile users often scroll differently, necessitating unique layouts for each device.
- Combine with session replays: Use a scrollmap to see where users stop and use session replays to understand the context of why they bailed.
- Place key info above the fold: Ensure that your primary value proposition is visible without requiring any scrolling.
Common mistakes
Mistake: Creating "False Bottoms" through formatting. Whitespace, line breaks, or large blocks can confuse users. Fix: Use a scrollmap to perform a depth test to see if visitors stop scrolling at these layout breaks.
Mistake: Ignoring dynamic elements. Scrollmaps may struggle to provide clear data for pages with infinite scrolling or independent scroll sections. Fix: Use other heatmap types or click maps for single-page apps with many independent sections.
Mistake: Relying solely on scroll data for element performance. A scrollmap shows if a user saw a section, not if they interacted with it. Fix: Use click maps to measure the effectiveness of specific buttons or links.
Mistake: Assuming aimless scrolling is high engagement. Sometimes users scroll randomly without reading. Fix: Cross-reference scroll depth with attention maps or movement maps to verify true engagement.
Examples
- Example Scenario 1: An e-commerce manager notices that 70% of visitors drop off before reaching the product testimonials at the bottom of the page. They move the testimonials higher up, into the "orange" zone, leading to higher trust signals and conversions.
- Example Scenario 2: A marketer uses a Free 30 day trial to determine if a long-form landing page is too long for their audience. They discover that only 10% of users reach the lead form, so they move the form above the average fold.
- Example Scenario 3: A UX team identifies a "cold blue zone" appearing right after a large image. They realize users think the page has ended. They remove the excess white space to encourage further scrolling.
Scrollmap vs Click map
| Feature | Scrollmap | Click map |
|---|---|---|
| Primary Goal | Measure visibility and depth | Measure interaction and intent |
| Key Metric | % of visitors reaching a section | Number of clicks on an element |
| Best Use Case | Optimizing page length and hierarchy | Testing button placement and navigation |
| Common Risk | Inaccurate data from random scrolling | Does not show content that was ignored |
FAQ
Can scrollmaps track mobile users? Yes. Scrollmaps are effective for optimizing responsive websites. They show where visitors stop scrolling on mobile phones and tablets, which often differ significantly from desktop behavior. This allows you to design a multi-device experience that works for all users.
What is a "false bottom" in web design? A false bottom occurs when a user believes they have reached the end of a webpage, even though there is more content below. This is often caused by large blocks of white space, horizontal lines, or formatting that mimics the end of a page. You can use a scrollmap to find these "dead zones" and fix navigation issues.
How do I know where the "fold" is? The "fold" is the bottom edge of a user's browser window when the page first loads. A scrollmap identifies the "average fold" by showing where most users' screens naturally cut off content before they begin scrolling.
Are scrollmaps better than click maps? Neither is "better"; they serve different purposes. A scrollmap tells you if users saw your content, while a click map tells you if they interacted with it. For example, if a button is in a "red" zone on a scrollmap but has zero clicks on a click map, you know the button is visible but not compelling.
How long should I run a scrollmap test? While the corpus does not specify an exact timeframe, tools like FullStory offer a 14-day trial to begin collecting digital engagement signals, suggesting that actionable patterns can emerge within two weeks of data collection.
