The lesson
Put a native social post frame over a real photo of the seller at work, so the channel and the person share one shot.
A full-bleed portrait photo shows a woman in a blue striped shirt packing a blue dog bowl into a box. An Instagram post frame from "pawnder" is laid over her hands, with a "Dog Bowl Set" product tag. Heavy white caps across the top read "SELL IN ALL THE PLACES" under the Shopify logo.
Don't copy the headline grammar without a reason for it. Keep the idea of compositing the channel's interface onto a real customer scene.
