You cannot tell whether your margin, your returns, or your ad spend are normal, because there is nothing to compare them against. The surveys that exist are built on whoever opted into a software company's list. We want one built on people who read this.
Nothing above needed anybody else's data. The comparison part does. Send your eight numbers in and you become one of the sellers the benchmark is built from. No name, no account, no company. Just the numbers.
Stored as one anonymous row. Never sold, never shared, never attached to your name.
