Heatmap
A heatmap is a data visualization tool that uses color gradients to represent user interaction intensity on a web page. Hot colors (red, orange) indicate areas of high engagement, while cool colors (blue, green) indicate areas of low engagement.
Understanding Heatmap
Heatmaps translate raw user behavior data into intuitive visual patterns that reveal how visitors actually interact with your pages—as opposed to how you assume they do. The gap between designer intent and real user behavior is often surprising. Elements you expect to draw attention may be completely ignored, while unexpected areas might receive concentrated interaction. Heatmaps close this knowledge gap and provide the evidence needed to make informed optimization decisions.
Three primary heatmap types serve different analytical purposes. Click heatmaps show where visitors click or tap, revealing which elements attract interaction and which are ignored. Scroll heatmaps show how far down a page visitors travel, identifying the point where attention drops off—critical for deciding where to place high-priority content like reviews and calls-to-action. Move heatmaps (or attention heatmaps) track cursor movement, which correlates with visual attention and reading patterns.
For Shopify store owners, heatmaps provide actionable insights at every level of the funnel. On product pages, they reveal whether customers are scrolling past your review section, whether they engage more with photo reviews or text reviews, and whether your add-to-cart button is positioned in a high-attention zone. On collection pages, they show which products and filters receive the most interaction. On the homepage, they reveal which promotional sections drive engagement and which are invisible to visitors.
The most valuable application of heatmap data is informing A/B tests. Rather than testing random variations, heatmap insights tell you what to test and why. If a heatmap shows that 70% of visitors never scroll to your review section, you know to test moving reviews higher on the page. If click data shows visitors tapping on non-clickable review images, you know to make those images interactive. This evidence-based approach to testing produces higher win rates and larger lifts than intuition-driven experimentation.
Why It Matters for E-Commerce
Heatmaps democratize user research by making behavioral data accessible to non-analysts. A store owner who might struggle to interpret a spreadsheet of click coordinates can immediately understand a heatmap showing that nobody clicks their carefully designed trust badge section. This accessibility makes heatmaps one of the most effective tools for building a data-driven optimization culture. For Shopify merchants, heatmap insights directly impact revenue by identifying wasted page real estate and overlooked conversion opportunities. Discovering that your review section receives minimal visibility—and then repositioning it to a high-attention area—can produce conversion rate improvements that far exceed the cost of the heatmap tool.
How Eevy AI Helps
Eevy AI's genetic algorithm approach to layout testing effectively automates what heatmap analysis suggests manually.

Click-through rate (CTR) is the percentage of people who click on a specific link, button, or call-to-action out of the total number who view it. It is calculated by dividing the number of clicks by the number of impressions, then multiplying by 100.
Conversion Rate Optimization (CRO) is the systematic process of increasing the percentage of website visitors who take a desired action, such as making a purchase, adding to cart, or signing up for a newsletter.
A/B testing is an experiment where two versions of a page, element, or experience are shown to different segments of visitors simultaneously to determine which version performs better against a defined metric.
Above the fold refers to the portion of a web page that is visible without scrolling. The term originates from newspaper publishing, where the most important stories were placed above the physical fold of the paper.
A review widget is an embeddable component that displays customer reviews on an e-commerce store. It typically renders star ratings, review text, customer names, photos, and filtering options within a defined section of a product page or homepage.
Mobile optimization is the process of designing and developing an e-commerce store to deliver a fast, usable, and visually effective experience on smartphones and tablets, accounting for smaller screens, touch interaction, variable network speeds, and mobile-specific user behavior.
