I consistently launch small vibe codes products. Slap ads on them and after a few weeks decide what to do with them without launching them anywhere else and am seeing good results. I see little to no reason to even launch them any other way at this point.

Which ad network do you use? Google, Meta, TikTok? I imagine you had pre-existing experience especially if it's Google, it's rare to get good RoI out of it unless you really know what you're doing. If you go with the defaults you'll get a few thousand "clicks", zero actual users among them.

How do you make the ads themselves? Are you a content creator yourself? Using AI? Hiring someone to make them?

Ads as a product validation strategy is old, and used to work great, but now is saturated and produces meh results in most niches.

If you're getting >CLV from your advertising cost of customer acquisition without PMF you're doing exceptionally well.
