SMBs don't usually have enough data to be able to guide optimization decisions in any meaningful way. Unless you're just sharing data between all other companies, which then results in the first problem I mentioned: you will not stand out. Usually creative agencies don't choose to work with two clients that compete with each other because of this dilemma, or if they do, they keep what works for each client strictly secret.
