Cheap Leads Can Be Bloody Expensive

A cheap lead is not a bargain yet

Your marketing report says leads cost $30. Lovely. Did any of them buy anything?

Cost per lead tells you what you paid to generate an inquiry. It does not tell you whether that person lives in your service area, needs something you sell, or thought they were calling the pizza place next door.

Cheap is a price. Good is a result.

For an established business, a useful lead number connects marketing spending to actual sales activity. Otherwise, your agency celebrates a green arrow while your office manager spends Tuesday explaining that you don’t repair microwaves.

What cost per lead actually measures

The calculation is simple:

Cost per lead = marketing spend ÷ new leads generated.

Spend $3,000 and generate 50 new inquiries. Your cost per lead is $60.

But define both sides before trusting the answer.

If that $3,000 covers advertising alone, you have an ad-spend cost per lead. Add $1,000 in campaign management and $500 in allocated landing-page costs, and your fully loaded figure becomes $90. Neither number is wrong. Switching between them without saying so is bullshit.

Then define a lead. For a local-service business, start with a unique new prospect contacting you about a service. A call and a form submission from the same person count once. Spam does not count. An existing customer rescheduling does not count.

Track unsuitable inquiries separately rather than quietly deleting them. Someone outside your service area still reveals something about your targeting.

A qualified lead meets your basic requirements: right service, right location, genuine need. Track cost per qualified lead alongside the raw number.

Clicks, page views, and phone-button taps are not automatically leads. Someone must actually make contact.

So what does a good one look like?

There is no honest universal answer. A gym trial inquiry and an emergency sewer replacement inquiry are not the same product.

Even within one trade, geography, competition, season, and the service advertised change the number. Shared leads sold to several businesses also deserve their own bucket. You are buying an opportunity to compete, not an exclusive conversation.

Your benchmark needs comparable leads and known outcomes.

Build it from the last 90 days, extending that window if you have low volume or a long sales cycle:

• Separate channels. Paid search, referrals, directories, and paid social behave differently.
• Separate major services. Don’t blend a $150 service visit with a $12,000 installation.
• Use consistent costs. Compare ad spend with ad spend, or fully loaded spending with fully loaded spending.
• Compare similar periods. A seasonal rush can distort both prices and conversion.

For example, suppose your last three comparable months produced qualified leads at $95, $105, and $100. That gives you a practical reference point around $100—not a law of nature.

A new campaign delivering qualified leads at $70 deserves attention. One delivering them at $140 needs an explanation. Neither gets a verdict until you check sales and job value.

That is a usable benchmark. “Someone online said leads should cost twenty bucks” is not.

Watch the cheap campaign lose

Here is an illustrative comparison for a service business. Both campaigns sell jobs with a $1,200 average ticket and a 45% gross margin. Marketing spending uses the same cost basis.

Campaign A looks cheap:

• Marketing spend: $2,400.
• New leads: 80. Cost per lead: $30.
• Qualified leads: 24. Cost per qualified lead: $100.
• Completed, paid jobs: 8. Marketing cost per customer: $300.

Campaign B looks expensive:

• Marketing spend: $2,700.
• New leads: 30. Cost per lead: $90.
• Qualified leads: 24. Cost per qualified lead: $112.50.
• Completed, paid jobs: 12. Marketing cost per customer: $225.

Campaign B’s leads cost three times as much. Its customers cost 25% less to acquire.

Each job produces $540 in gross profit before marketing. Campaign A generates $4,320, leaving $1,920 after marketing. Campaign B generates $6,480, leaving $3,780.

That remainder is not net profit. Overhead still needs paying. But B leaves $1,860 more to cover it.

It also creates 50 fewer inquiries to process. More callbacks and dead-end estimates can push up your office labor percentage without producing another dollar of sales.

Don’t blame the lead for your broken follow-up

Expensive customers do not always mean bad marketing.

If calls ring out, estimates sit untouched, or nobody follows up, good inquiries can produce lousy results. Pricing, appointment availability, and reviews can also affect whether a qualified prospect buys.

Track each lead through a few plain stages: received, qualified, contacted, booked, sold, lost.

Record a specific loss reason. “Too expensive,” “outside service area,” and “we never reached them” describe different problems. “Bad lead” describes almost nothing.

Give leads time to mature, too. Comparing yesterday’s inquiries with last month’s completed jobs will make the newest campaign look worse than it is.

Fix the counting first

Monday morning, pull your last 30 leads. Match them to spending and sales records.

• Remove duplicates and spam.
• Mark which were qualified.
• Record contact attempts, bookings, sales, and loss reasons.
• Calculate cost per lead, cost per qualified lead, and cost per customer by source.

If leads are unsuitable, fix targeting. If qualified people never hear back, fix follow-up. If one source reliably produces profitable work, test increasing its budget.

Do not buy more leads until you know what happened to the last batch.
