CPA (Cost Per Acquisition)
How much you spend on ads to land one paying customer or qualified lead — the metric that actually matters.
Definition
CPA (Cost Per Acquisition) is the total ad spend divided by the number of actual customers or qualified leads you got. If you spend $1,000 on Google Ads and close 5 new clients, your CPA is $200. Unlike CPC (clicks) or CPM (views), CPA tells you the real cost of growing your business. The right CPA depends on what a customer is worth to you — a Miami plumber willing to spend $80 to land a $400 service call has healthy economics. CPA is the number every business owner should track weekly. We obsess over CPA on /pricing.php.
Why it matters in Miami
Miami service businesses — HVAC, roofing, legal — often have CPAs between $100 and $500 because of high competition. Knowing your CPA versus customer lifetime value (LTV) is the difference between scaling profitably and quietly going broke.
Example
A Hialeah HVAC company tracks CPA at $145 per booked installation; since each install averages $4,200 in revenue, they confidently raise their daily ad budget by 4x.
