Heatmap

Different heatmap types answer different questions about user behavior^[1]. Click maps show where users click — useful for identifying whether users are engaging with important CTAs, clicking on non-clickable elements (confusion), or ignoring key page sections. Scroll maps show how far users scroll before leaving — the most common finding is that 50-70% of users never scroll past the fold, meaning content placed below the fold is seen by a minority. Move/hover maps show where mouse cursor goes — research shows 88% correlation between cursor position and eye tracking on desktop, making this a proxy for attention. Rage click maps (offered by Hotjar and Clarity) specifically highlight where users click repeatedly in frustration — these spots need immediate investigation for broken elements or unmet expectations.

Heatmaps bridge the gap between analytics data and user experience insights^[1][2]. If organic traffic is high but conversion rate is low, heatmaps reveal why: is the CTA in the scroll-dead-zone? Are users clicking on images expecting them to be links? Is navigation drawing attention away from the main content? For content pages, scroll maps are critical — if 90% of users leave before scrolling to the main argument of a long article, the introduction needs to better establish value early. If users are clicking on a heading expecting it to link to more information, add an internal link. Session recordings (often paired with heatmaps in tools like Hotjar) let you watch actual user sessions to see exactly what caused a user to leave or convert.

Microsoft Clarity is the best starting point for heatmaps — it's completely free with unlimited sessions and integrates directly with Google Analytics 4^[2]. Set up requires adding a small JavaScript snippet to your site's <head>. Collect at least 1,000 sessions on a page before drawing conclusions from heatmap data — small sample sizes produce misleading patterns. Segment heatmaps by device type (desktop vs. mobile) separately since click and scroll behavior differs dramatically. Segment by traffic source — organic search visitors often behave differently than paid or social visitors because of different intent. Run heatmaps on your highest-traffic landing pages and key conversion pages first, where improvements have the greatest impact. After implementing changes based on heatmap insights, run A/B tests to confirm the change improves conversion rate rather than just anecdotally changing click patterns.
