69Paid ads

Short version: at the start, probably not.

Ads multiply what already works. If you have a project people arrive at and stay in, ads will bring more of the same people. If they arrive and leave, ads only speed up the draining of your money.

So the order is: free channels first, watch whether people stick. They stick - try paying, starting with small amounts. They don't - money won't help, the project itself needs fixing.

What is genuinely worth money at the start: a domain, an AI subscription, and a server if you need one. That's it. The rest is time and attention.

One exception: if the product sells immediately and you can work out what one customer costs, ads become arithmetic and can pay from day one. But that's no longer a first project.
