How many daily unit sales when first starting are good / bad?

How many unit sales when first starting are good/bad?

I realize this will be different for every product but if you assume a new brand and product, priced competitively, A+ content, relatively strong demand for the category and moderate competitive landscape, keyword optimized and PPC active (no further outside marketing, eg influencers or paid spend)… TL;DR assume you’ve set things up right.

What would be a good sign of life re: avg daily unit sales in weeks 1-6 vs something that’s just not worth the squeeze?

Again, appreciate this is impossible to say but I’m curious to hear from seasoned sellers who’ve launched new products and what their hurdle rates are based on experience.
