I recently just updated the product mockup for my MVE training using the method I describe inside the classroom and the lead quality on my ads has jumped surprisingly.
I went from filtering out a large number of old Yahoo and AOL email addresses that never seem to open my emails to immediately garnering the interest of a number of established reputable brands in adjacent markets.
I've changed other things about the ad copy, mockup, landing pages, etc...
But I can see from a straight a/b comparison that this new mockup is doing a significant amount of heavy lifting.
Below: First is the new mockup, Second is the old one. What are your first impressions?
