SEO vs paid ads when you have no money
You have a small budget and need to know whether to spend it on ads or on time.
Ads buy certainty, search buys compounding
Paid traffic starts today, stops the day you stop paying, and tells you within a week whether the message works. Search takes a quarter to say anything and then keeps delivering for years without further spend. Those are different products.
The real argument for search when broke
Not that it is free, it costs time, which is the scarcest thing you have. The argument is that the asset persists. A page that ranks is working at three in the morning eighteen months later.
The honest case against
It is slow, it is uncertain, and you may do everything right for four months and see nothing. If you need revenue this quarter to survive, that is a real reason to buy traffic instead, and no amount of enthusiasm changes it.
The comparison that matters is not cost per click
Ads buy traffic that stops the day you stop paying. Search builds an asset that keeps returning after you stop working on it. Those are different instruments and comparing their per-click cost is a category error. The real question is whether you can survive the months before the asset produces anything, because that is the only variable that decides it.
The case for ads
If you need to validate demand this month, ads will tell you in a week what search takes a quarter to reveal. That is a genuinely good reason to spend, and it is a research budget rather than an acquisition budget. This site spent $0 because it had time and no money, which is a specific situation and not a universal recommendation.
Measured, not asserted
Zero to 100,542 users on $0 of advertising, over 224 days. The first three months produced 1,508 clicks in total, which is what "slow" means in practice.

Where this goes deeper
Every number on this page comes from one complete dataset: one product taken from zero to 100K+ users on search alone, with nothing spent on advertising. The full argument is Chapter 1 and Chapter 30 of the book. Five chapters are free to read.
