scaling product

Last night, I learned from a YouTube video that scaling advertising efforts doesn't always require a high budget. Instead, it's more about identifying the brand's unique selling points and enhancing the existing product or finding new products within the same niche. What are your thoughts on this approach?

tbh money makes money, u can focus as much as u want on USP etc etc but in the end a winning ad creative, a good funnel and budget can make u win
