What moves people to purchase isn't solely "good marketing." Sometimes, it's really genuine, thoughtful work.
As it becomes easier to build and market things, the things that feel genuinely cared for may become more valuable to buyers.
Edit: a really good product with really good marketing is going to win. But I think thoughtfulness is increasingly going to be part of what makes marketing good.
What gets me to enter credit card details
Genuine humans behind the product. I like knowing there's a real person in there who cares deeply about the thing they're making.
Quality through and through. Not just a good product. Good copy, good support, good packaging, good details. The whole thing feels cared for.
Simple words that hit. A few really good (simple) words can make me want something more than a 500-word sales page ever could. That's true for emails! I'm a scanner of sales and marketing copy. Why more words when less words do trick.
Cleverness. A little detail that makes me think, oh, that was clever. I get the vibe that the creator really thought through everything. Especially the stuff I would have never thought of.
Seeing myself in it. The best brands and products make me feel like the product was made for me. For example, as I've been dabbling in building with agents, I've had to manage multiple terminals and agents. Solo's messaging: "stop losing valuable time managing terminal tabs." Yes please!
What gives me pause
Too corporate. Once the corporate jargon is the headline, I'm out! I'd much rather support a genuine human who is doing this for passion's sake.
Too many (big) words. If my eyes don't get the gist on one simple scan, it's probably not for the dense like me. Even for the smart maybe!
I don't trust the people behind it. This goes back to supporting genuine humans. I don't think humans will always get it perfectly right, but being genuine and good should come naturally. If the creator is cussing out users who don't like a feature on reddit threads, eek!
Bad support. If I end up on an automated call system that doesn't get me the support I need to go about my day, ah! That's not very fun. There are enough good quality builders out there, I am going to find the one that is higher touch.
All to say, the best marketing tactics don't actually start with emails or booth presence. They may actually start with asking "what gets me to enter my credit card details?"
