RHINO testing with the University of Cambridge showed us something brutal about reach: if an asset scores "Single A" 25% glance-readability, you have effectively hidden your product from 75% of adults.
When brand penetration drops, marketing teams scramble to adjust media spend and audience targeting. But ad spend only buys impressions. It cannot force a human eye to decipher unreadable creative on a six-inch phone screen.
Fixing reach requires making visual content accessible to everyone who might buy you.
Most brand teams assume this begins and ends with the primary hero image.
It was never just the hero.
---------------------------------------------
Visual friction follows the shopper across every single touchpoint.
---------------------------------------------
An unreadable hero loses the initial basket on a crowded mobile search grid, an unreadable carousel infographic loses the conversion on the PDP, and low-contrast pack graphics get walked right past on the physical shelf.
That is why we built RHINO on Cambridge visual clarity data to test the entire visual ecosystem:
• Primary hero images and secondary PDP carousels
• Enhanced A+ content and comparison tables
• Retail media ad banners
• Point of sale displays and physical pack design.
When visual assets pass automated contrast and glance-readability across all of these surfaces, your brand shows up consistent from screen to shelf and back. End-to-End.
