Are your conversions high enough?

This is almost subjective - there are industry standards you can google (different for ecommerce vs SaaS vs cart page vs PPC landing page etc etc. - differs by geography too), but most of that data online is outdated, plus, industry averages should be your minimum goals (you want your conversion rate to be at least what the industry average is). Plus conversion rate is a big lever to increase your sales/OMTM without increasing your acquisition rate (i.e same number of visitors or downloads, but higher conversion rate = more customers or users). Almost subjective because a good conversion rate is always higher than your current conversion rate.
