Describe what CPA, CPC, and LTV stand for and why a small business should track them.

• A. CPA = cost per acquisition; CPC = cost per click; LTV = lifetime value of a customer; they measure efficiency, channel performance, and long-term profitability.
• B. CPA = cost per action; CPC = cost per currency; LTV = loan to value
• C. CPA and CPC are irrelevant; LTV is a stock metric
• D. CPC stands for cost per customer; CPA for click per action

Answer: (A)

Understanding how marketing costs relate to customer value is essential for small business success. CPA, or cost per acquisition, tells you how much you spend to turn a prospect into a customer. CPC, or cost per click, shows the price you pay for each click in paid advertising, helping you assess how costly your ads are to drive traffic. LTV, or lifetime value of a customer, estimates the total revenue a customer generates over their entire relationship with your business, which informs how much you should invest in them.

Tracking these metrics gives you a clear view of efficiency, channel performance, and long-term profitability. If your CPA is too high compared to the revenue a customer brings over time, your marketing isn’t sustainable. CPC helps you optimize bidding and budgeting across channels to get more value from each dollar spent. LTV helps you plan retention, upsell, and pricing strategies, ensuring that your acquired customers contribute meaningfully to profits over the long term. For a small business, these metrics guide budget decisions, campaign optimization, and growth planning.
