The honest answer is that it depends on your margin and your patience. Here is how to work out which applies to you.
The honest answer is that it depends on your margin and your patience, and anyone who answers it without asking about both is selling something.
The two numbers that decide it
Paid works when your contribution margin comfortably exceeds your cost per acquisition, and when you need volume sooner than organic can deliver it. Organic works when you can afford to wait two to three quarters for compounding returns, and when your category has genuine search demand rather than demand you would have to create.
If your margin is thin, paid rarely rescues it — you are buying every sale at a fixed cost forever. If your sales cycle is long, paid attribution will mislead you unless the reporting window matches it.
They are not actually alternatives
The framing is a false choice. Paid search is the fastest way to find out which messages and which queries convert; organic is the cheapest way to serve them at scale once you know. Running paid first as a research budget, then building content against what converted, costs less than guessing at either in isolation.
What we recommend to most clients
Start paid on a narrow set of high-intent terms, accept that you are buying information as much as revenue, and reinvest what you learn into organic. Review the split quarterly against contribution margin rather than ROAS — ROAS flatters campaigns that harvest demand you already had.
