- VISUALIZE CUSTOMER DENSITY WITH HEAT MAPPING
When you’re trying to understand your customers, spreadsheets alone can only tell you so much. That’s where heat mapping comes in. By turning raw location data into visual color gradients, you can see exactly where your customers are concentrated—and where there may be gaps.
Whether you’re managing territories, planning site locations, or targeting marketing campaigns, heat mapping reveals patterns that raw data just can’t. And thanks to modern tools like Mapline, it’s easier than ever to get started—even with no technical background.
What Is Heat Mapping and Why It Matters
Heat mapping is the process of visualizing data points on a map using gradients of color to represent intensity or volume. The brighter or deeper the color, the higher the activity in that area. For businesses, this means visualizing customer locations, sales activity, support requests, and more.
Common use cases for heatmap visualization include:
- Identifying high-performing regions
- Pinpointing underserved areas
- Optimizing service coverage or delivery zones
Knowing how to make a heat map or how to create a heat map opens the door to better decision-making across marketing, sales, operations, and logistics.
