Why Heatmaps Matter for Conversion Optimization
Heatmaps translate raw click, scroll, and movement data into visual insights. Instead of guessing where users struggle, you see it. Studies show that websites using heatmap data improve conversion rates by 20–35% on average after implementing changes based on behavioral insights.
Two tools dominate this space in 2024: Hotjar and Microsoft Clarity. Both offer heatmaps and session recordings, but they serve different needs. Let’s break down exactly how they compare.

Hotjar: Strengths and Limitations
What Hotjar does best
- On-site surveys: Ask visitors why they left or what they were looking for. This qualitative data is invaluable.
- Feedback widgets: Users can highlight page elements and rate their experience.
- Funnel tracking: Visualize where users drop off in multi-step forms or checkout flows.
Where Hotjar falls short
The free plan’s 35 daily sessions cap is restrictive for sites with more than a few hundred daily visitors. Scaling to the Business plan means spending $80–$171 per month depending on traffic volume. For e-commerce stores on Prestashop handling 10,000+ sessions daily, costs add up quickly.
Microsoft Clarity: Strengths and Limitations
What Clarity does best
- Unlimited data at zero cost: No session caps, no traffic limits, no paywalls.
- Smart detection: Rage clicks, dead clicks, and excessive scrolling are flagged automatically.
- Google Analytics 4 integration: Link sessions directly to GA4 metrics for deeper context.
- Copilot AI summaries: Get plain-language insights about user behavior trends.
Where Clarity falls short
Clarity lacks any feedback or survey mechanism. You see what users do but can’t ask why. There’s also no built-in funnel visualization or A/B testing integration.
Which Tool Should You Choose?
For small to mid-size websites focused on understanding navigation patterns and fixing UX issues, Clarity delivers outstanding value at no cost. For conversion-focused teams that need qualitative feedback, NPS surveys, and funnel analysis, Hotjar’s paid plans justify the investment.
Many of our clients at Lueur Externe run both tools in parallel—Clarity for unlimited session data and Hotjar for targeted user surveys during campaign launches.
Installation Tips
- WordPress: Both tools offer official plugins. Installation takes under 2 minutes.
- Prestashop: Add the tracking script via the header module or use a dedicated analytics module. Lueur Externe, as a certified Prestashop expert since 2003, typically integrates both during site audits.
- Performance: Combined, both scripts add less than 30 KB (gzipped) and load asynchronously, so Core Web Vitals impact is negligible.
Conclusion: Data-Driven Decisions Start Here
Whether you choose Hotjar, Clarity, or both, heatmap analysis is no longer optional—it’s essential for any serious optimization strategy. The key is not just installing tools but acting on the insights they reveal.
