A lead is worth the deal value multiplied by the rate it closes at, minus what it cost to produce. Until somebody has measured the close rate, a lead count is a vanity metric wearing a suit.
This matters for property valuation more than it looks, because lead generation is how a large share of business-to-business and service properties monetize, and it is the revenue model most often presented without the numbers that would make it checkable.
The arithmetic, and where it goes wrong
Lead value is not complicated:
lead value = average deal value x close rate
A property producing 20 leads a month, into a business closing 10 percent of them at 8,000 dollars, is producing 16,000 dollars a month in expected revenue. That is a real number and it prices the property quickly.
Three places it falls apart in practice:
Nobody knows the close rate. This is the normal state. The property owner hands leads to a client or a sales team and never hears what happened. Every number downstream is then a guess presented as a measurement.
Lead quality varies by source and nobody splits it. Leads from a comparison page and leads from a definition page close at completely different rates. Averaging them produces a number that is wrong for both, and it usually flatters the source producing more volume.
Attribution stops at the last click. The page that gets credited is often not the page that did the work. This is not fixable to perfection, but it is improvable by looking at query-to-page association rather than trusting a single-touch model.
What makes lead value durable
- The intent is upstream of the form. A lead arriving from a pricing or alternatives query is a different animal from one arriving from a newsletter popup on a definition page.
- The property is the first party. Leads collected on a property you control, from queries you rank for, are an asset. Leads bought from an aggregator are inventory.
- The receiving business can absorb them. A property generating leads into a business with no capacity to follow up is producing a number, not revenue. This is more common than anyone admits.
How I would measure it on a property with no history
New properties have a chicken-and-egg problem: no leads yet, so no close rate, so no value. The workable substitute is to measure the ingredients rather than the outcome:
- Intent-carrying impressions. How many appearances are on queries attached to a decision? This is the raw material.
- Route completeness. Can a visitor on those pages actually start a conversation, in one step, without hunting?
- Category deal value. What does a closed deal look like in this subject? A property in enterprise infrastructure and a property in consumer services can produce identical lead counts with a hundredfold difference in value.
Those three give you an expected value with honest error bars, which is a more useful thing to hand a buyer than a confident number with no close rate behind it.
The measurement that changes behavior
If you only add one thing to how you track lead generation, make it this: record which query and which landing page each lead came from, and then go back and mark which ones closed.
It is unglamorous, it requires the sales side to cooperate, and it is the only way to find out that 70 percent of your closed revenue comes from four pages you were about to deprioritize because their traffic was small.
That specific discovery, in some form, is the most common useful outcome I have seen from doing this properly. The pages that produce revenue are almost never the pages that produce traffic, and a property being valued on traffic is being valued on the wrong pages.
A note on contact routes
Since we are on the subject: a lead generation property with a plain email address on it is leaking. Not a privacy point ... a measurement one. An emailed lead has no source data attached, which means it cannot be attributed, cannot be scored, and cannot be counted in any of the arithmetic above. A form with the source recorded is worth more than the same lead arriving in an inbox, even though it feels less personal.
