We’ve talked about the "5-second rule." But let’s talk about the geography of those 5 seconds.
On mobile, the "Above the Fold" area is roughly 600 pixels high.
This is the most expensive real estate in your business.
If a user has to scroll to understand what you sell or how to buy it, you have failed.
The Perfect Mobile Hero Layout
Imagine your phone screen. Here is exactly what needs to fit without scrolling:
The Visual (50% of screen): High-res image of the product. NOT a lifestyle shot where the product is tiny. A clear, zoomed-in shot of the item.
The Headline (15% of screen): Clear benefit. "Sleep Better Tonight."
The Social Proof (5% of screen): ⭐⭐⭐⭐⭐ (1,240 Reviews).
The Price (10% of screen): Clear font. If on sale, show the slash-through price to trigger value perception.
The CTA (20% of screen): A full-width "Add to Cart" button.
Common "Hero" Mistakes That Kill Conversions
❌ The "Lifestyle" Takeover: The image is a model laughing on a beach, but I can't see the jewelry she's wearing.
❌ The "Pushy" Pop-up: Immediately hitting them with "Sign up for 10% off" before they’ve even seen the product. (Google punishes this, and users hate it).
❌ The "Mystery" CTA: The "Add to Cart" button is below the fold.
The "Thumb Reach" Rule
Your Call to Action (CTA) button needs to be within the "Thumb Zone."
If a user holds their phone with one hand, can they tap "Buy" without stretching their thumb to the top of the screen?
Sticky CTA: The Ultimate Cheat Code
If your product explanation requires scrolling (and it usually does), implement a Sticky Add-to-Cart Button.
As the user scrolls down to read ingredients/specs, the "Add to Cart" button stays fixed at the bottom of the screen.
Impact: We’ve seen Sticky CTAs increase mobile conversion rates by 15-20% overnight.
Your Homework: Open your site on your phone. Do not scroll.
Can you see the Product, Price, and Buy Button all at once?
If not, reduce your font sizes, crop your image, and tighten that spacing.
