Honestly, think hard on this. As Disney always said.

“Don’t fuck with the duck”

Build out all your funnel, email automation, email collection, retargeting tools like pixels, ect now so that the systems are in place for when you start to scale. Email is your best friend. If you’re selling well known brands performance max Google ads will work really well (the key is that your products already have search volume)

Congrats! Are you new to e-commerce? I find the consumer behaviour to be really interesting. I work for a company with stores and online - I run online. Online average orders are way higher, the consumer is more dedicated, and you’ll be blown away at how some people prioritize their spending.
