Does heatmap.com slow down websites? (Split Test Results)
heatmap’s innovation of Site Speed Protection has proven we have zero impact on website performance. Don't believe me? I'll prove it.
When it comes to site speed and load performance, heatmap stands out from other tracking software with its dual snippet approach.
- Our preprocessor snippet, which tags the user ID, is exceptionally lightweight at under 10KB. This ensures rapid execution without compromising performance.
- The primary behavior snippet loads asynchronously, preventing any blockage of the main thread. This design allows heatmap to track all user interactions efficiently while maintaining optimal site speed.
- Revenue tracking is handled by a second pixel rather than the global header pixel, significantly reducing the load on each session.
Together, these features create a high-performance tracking mechanism with minimal impact on load times. Split tests further prove the effectiveness of this setup in maintaining fast, responsive websites.
Formal A/B Test for Site Performance
Historically, website owners have been hesitant to install heatmaps due to concerns about "site speed impact." Some heatmap tools have been reported to negatively affect site speed, leading to performance concerns.
heatmap’s Site Speed Protection has proven to have zero impact on website performance.
To back this up, we ran a formal A/B test with over $2 million in revenue, proving that site performance remains identical with and without our snippet.
We ran a controlled A/B test on a 9-figure eCommerce brand to measure the impact of heatmap’s tracking on website performance.
The results?
Zero impact on website performance!
Here’s what the data showed:
- Control Group (without heatmap):some text
- Revenue Per Session: $3.65
- Total Revenue: $1.2 million
- Experiment Group (with heatmap ):some text
- Revenue Per Session: $3.65
- Total Revenue: $1.2 million
This statistical proof confirms that heatmap does not slow down website performance or affect revenue in any way - despite what third-party site speed tools may suggest.
There’s nothing more reliable than a controlled, data-driven experiment to show that heatmap delivers game-changing analytics without compromising performance.
