Is it possible to sell a product by the first interaction ?

I started a shopify store, I found a relatively good product that was selling on others side ( the product was something useful for babies) but I dont know how they were selling it. So it is possible to sell something by the first interaction with the user ( cold traffic), does it just has to be an f*kn amazing product, or is it very very hard to sell something to cold traffic, and I need to follow a new strategy to first worm up the traffic before offering the product.
Has somebody some experience in it ?
