I have spent seven years inside Meta ad accounts, and almost all of it on lead generation rather than ecommerce. That means healthcare and clinics, real estate, home services and lawn care, hospitality, B2B SaaS, local services, and lending and financial services.
The range runs from single location businesses on tight local budgets to a US home services brand spending $300,000 a month across Florida and Georgia, and a portfolio of 25+ client accounts running at the same time.
Running that many accounts at once is what led me here. Two accounts can post the same cost per lead and have completely different businesses behind them. The only way to tell them apart is to follow the lead past the form, which is why I spend as much time in CRMs and Events Manager as I do in Ads Manager.
