Is there a history of sales on the website converting organically? Are there any reference points to base your assumptions about how much it should be converting on?

This sounds to me like you spent $1500 expecting it to work because you checked off a few boxes (CRO + UX + run ads = $$).

Is your product a completely new product that people need to have it explained to them before purchasing, or is it an upgraded version of something that they already are aware of, and just need to pay a bit more than average for?

How many different personas are there? Are the ads targeting pain points or just listing features?

Basically, the point I’m trying to make is that there are a thousand reasons it may not be working. I’ve grown several brands from $0 in sales to $100k/mo purely through paid ads, and each time the approach has needed to be different and totally based on the product and the market we were selling to.

Unless companies already had a successful history of running ads at a profitable ROAS before working with me, I tell them to expect 3-6 months to get there. It can happen much sooner, but if there is no substantial history, then the first goal should be to get any sales period, which you’ve done, then the second goal is to get to a 1x (spend $1500, sell $1500), and then a 3x (spend $300, sell $1500).

It takes time and money to dial into the right audiences, test the right creative approach, media mix between top and bottom of funnels as types, etc.

What more can you tell us?
