I think I found my new home. Substack is INSANE. Last night, before published a single post, I already had 7 paid subscribers...
I hit live on my first post last night. Below is a teaser but it's also loaded with my master prompt for creating main images that convert.
I shared how we ran a simple test on an Amazon shoelace listing.
30 shoppers. Two images.
Result: 29–1. (this is more rare than you think)
The “losing” image? Objectively better. Clean, polished, perfect flat lay.
The winner? The same laces… shown a different way.
Almost every comment said the same thing: “Now it clicks.”
Most brands optimize for how their product looks.
Shoppers are trying to understand if it works.
Those are not the same thing — and only one gets the click.
We broke down the full test with visuals and our process for main image split testing (AND the exact prompt you can use today to generate winning concepts).
