Glance readability is so basic, most brands don't know they need to test for it.
That's exactly why it's a competitive advantage.
Everyone admits that no one reads much online.
Often, because it's simply too hard because the text is too small.
90% of hero images fail glance readability on mobile.
Brand teams don't even realise because they assume "mobile optimised" means the same thing.
It doesn't.
Mobile optimised is about responsive sizing.
Mobile-ready is about being readable on mobile.
You need mobile-ready, glance-readable heroes. Tested. Proven.
"Glance-readability" is about whether shoppers can actually read your critical messages in the time they give you.
How much time?
400 milliseconds. A glance.
Tobii Eye-tracking research with my friend Jon Ward shows shoppers don't read on mobile - they visually scan.
They fixate on hero images for less than half a second before scrolling.
What can your brain digest in 400 milliseconds?
4 messages. That's it.
Which 4 messages matter most?
→ What brand?
→ What format/type?
→ Which variant?
→ What size/count?
The 4Ws. The basics shoppers need to confirm: "Is this what I want?"
Only if there's space do you add: "Why choose this one?"
==========================
Think about Google Maps.
Glance-readable by design ON MOBILE.
==========================
You process directions instantly so you don't miss a turn.
No squinting. No friction. Just clarity at speed. Life saving readability.
Your hero images should work the same way. Your conversion is at stake.
But most don't test for glance-readability.
Poor contrast. Tiny text. Too many messages competing for attention. The brand works in-store, but online as a thumbnail? Shoppers give up. They scroll past. They buy from someone who made it easier.
===================
Visual friction kills conversion.
===================
Optimising for attention is necessary but not sufficient. Shoppers need to glance-read on their device of choice - their phone - without the pain of deciphering unreadable text.
Make it easy to read. Make it easy to buy.
