Heatmap.
A heatmap visualizes user behavior on a webpage through color codes: Red shows areas with high activity (clicks, scroll depth, mouse movement), blue shows areas with little attention. It helps identify UX problems and optimization opportunities.
Heatmap — Explained in Detail
A heatmap is a visual representation of user behavior on a webpage. Instead of abstract numbers (bounce rate, time on site), it concretely shows where users click, how far they scroll, and where their attention lies. There are three main types: Click Heatmaps (where do users click? — shows whether CTAs are perceived), Scroll Heatmaps (how far do users scroll? — shows whether important content is seen), and Move Heatmaps (where do users move the mouse? — correlates with gaze direction).
Typical insights from heatmap analyses: CTAs are not seen (too far down, wrong contrast), important content is 'below the fold' (below the scroll boundary), users click on non-clickable elements (expecting a link), form fields are skipped (too many fields, unclear labels), and navigation is not used as expected. These insights form the foundation for data-driven UX optimization and A/B tests.
The most popular heatmap tools in 2026: Hotjar (most popular solution, heatmaps + session recordings + surveys), Microsoft Clarity (free, from Microsoft), Mouseflow, Lucky Orange, and FullStory. For Swiss SMEs, DLM Digital recommends: Start with Microsoft Clarity (free, GDPR-configurable) or Hotjar (from 39 EUR/month). Analyze the most important pages monthly (homepage, landing pages, contact page) and derive concrete optimizations.

Yes, when correctly configured. Modern heatmap tools anonymize data automatically: text inputs are masked, no personal data is stored. You must: include heatmap tracking in your cookie banner (obtain consent), update your privacy policy, and configure session recordings so that form fields are masked. Microsoft Clarity and Hotjar offer GDPR-compliant configuration options.
Monthly for your most important pages (homepage, top landing pages, contact page). When making changes to the website: before-and-after comparison. Before A/B tests: Heatmaps provide hypotheses for test ideas ('Users don't scroll to the CTA → place CTA higher'). Collect at least 1,000 sessions per page before drawing conclusions — with less data, the patterns are not meaningful.
