Damn good advertising. Most ads aren’t that — they’re technically correct and completely forgettable: right logo, right colors, a headline that could run for any competitor with the name swapped out.
What actually moves someone isn’t creative polish, it’s specificity of the offer — a claim precise enough that the reader either recognizes their exact problem in it or scrolls past knowing it wasn’t for them. That precision is uncomfortable to write and is exactly why most ads avoid it.
Polish is optional. A specific, falsifiable claim isn’t.
