Which metric best indicates the efficiency of paid search campaigns in real estate?

• A. Cost per lead (CPL)
• B. Click-through rate (CTR)
• C. Impressions
• D. Return on ad spend (ROAS)

Answer: (A)

Efficiency in paid search campaigns hinges on how much you spend to turn exposure into a real opportunity. In real estate, the big result you want from ads is a lead you can work with, so the metric that directly reflects this is cost per lead. It shows the total ad spend divided by the number of leads generated, revealing how efficiently the budget is producing potential clients. A lower cost per lead means you’re getting more leads for each dollar spent, which is the essence of efficiency.

Click-through rate indicates how often people click the ad, but it doesn’t tell you whether those clicks become leads or how much each lead costs. Impressions measure reach, not performance or cost. Return on ad spend looks at revenue relative to spend, which is important but can be influenced by varying deal sizes and long sales cycles, and doesn’t directly show the efficiency of generating leads.

So, cost per lead is the best single measure of how efficiently paid search is turning spend into actionable real estate prospects.
