In particular, if someone makes it through to the end of your landing page, you have a final opportunity to convince them to convert (incidentally, this is a good place for another CTA).

“Now, for the vinegar. Starting with the headline, if creating headlines was a waste of time, why do I need this product at all? And why write headlines at all in the first place? Do their customers really say to themselves (in their owns heads), ‘this is a waste of time?’ Probably not. They say something more like ‘I don’t want to do this,’ ‘I suck at this,’ or ‘I hate writing.’ Big difference. They attempted to call out a problem, but in this case there’s a big disconnect and it’s negative for no real reason. Instead, if they want to call out a problem, they need to pick one that the market connects to.
