What this video covers
Show a design for five seconds, then ask what you remember. What sticks is what the layout really highlights - and what it quietly obscures. You can try this test right here on the page.
Whatever you just retained is roughly what a real visitor keeps too. If the brand, the offer and the main action don't survive five seconds, the page is making its first impression without them.
