I lost three education platform clients because I kept building hero sections that took up 100% of the viewport. They looked stunning in my portfolio. Users hated them.
The analytics told the whole story. Bounce rates sat at 68% because visitors couldn't see any actual content without scrolling. They assumed the page was empty or broken.
What the heatmaps showed
Heatmap data from Hotjar revealed something obvious in hindsight. Users who landed on these sites moved their mouse down immediately, searching for content. When they found nothing but a giant image and vague tagline, 7 out of 10 left within 8 seconds.
The clients who fired me had course catalogs, pricing tables, and testimonials that no one ever saw. All buried below a hero section that served my design ego, not their business goals.
The fix took five minutes
Reducing hero sections to 60% viewport height and showing a preview of the content below changed everything. Bounce rates dropped to 34%. Time on page increased from 12 seconds to 2 minutes 40 seconds.
Your hero section exists to get people into your content, not to showcase your Unsplash photography skills. If users can't see your value proposition and next section simultaneously, you've already failed.
