Somebody asks how your marketing is going and you say “pretty good, I think.”

That’s the honest answer for most owners, and it’s uncomfortable, because you’d never accept it about any other part of the business. You know your material costs. You know roughly what a job takes. But the marketing line just sits there every month, producing something, and the closest you get to evaluating it is a general sense of whether the phone feels busier than it did.

The reason isn’t laziness. It’s that the reporting most businesses receive doesn’t answer the question. Impressions are up 34%. Reach expanded. Follower count grew. All accurate, none of it telling you whether any of it turned into money.

You can answer this yourself, with 4 numbers, most of which you already know. No software required. Here’s the actual math.

The 4 Numbers

Write these down for your own business before reading further. Estimates are fine.

1. Average job value. What a typical customer pays you. If your work varies wildly, use the average across the last 20 jobs.
2. Your close rate on inbound leads. Out of every 10 people who contact you, how many become customers? Most service businesses land somewhere between 20% and 50%. If you genuinely don’t know, guess low and correct later.
3. Monthly marketing spend. Everything. Whatever you pay a provider, ad spend, sponsorships, printed materials, the booth fee. Total it honestly.
4. Inbound leads per month. People who contacted you without you contacting them first.

Those 4 numbers answer nearly every question you have.

The Math That Settles It

What a lead is worth to you:

Average job value × close rate = value per lead

If your average job is $2,400 and you close 30% of inquiries, each lead is worth $720 to you.

What you’re paying per lead:

Monthly marketing spend ÷ leads per month = cost per lead

If you spend $1,500 and get 12 inquiries, you’re paying $125 per lead.

Whether it’s working:

$720 in value against $125 in cost. That’s a 5.7 to 1 return before costs of delivering the work, which is comfortably positive for most service businesses.

Your break-even, which is the number I’d actually keep in your head:

Monthly spend ÷ value per lead = leads needed to break even

$1,500 ÷ $720 = 2.1 leads a month.

That reframe is the point of this whole exercise. “Is $1,500 a month worth it” is a hard question you’ll answer with your gut and your anxiety. “Do I need 3 inquiries a month for this to pay for itself” is a question with an actual answer, and for most service businesses the number is small enough to change how you feel about the spend entirely.

Did You Know? Most owners who run this calculation for the first time discover their break-even is 1 to 3 jobs a month. The spend felt enormous in isolation and turns out to be covered by a fraction of what it produces. The number was never the problem. Not knowing the number was.

Track Where Leads Come From, Because Nothing Works Without It

Everything above depends on knowing your lead count, and most businesses don’t track it. Here’s the minimum viable version.

Ask every single caller how they found you. Not sometimes. Every one. Then write it down. A notebook by the phone works fine, and a shared spreadsheet works better.

You need 5 categories:

Source	What It Means
Search	Found you on Google, Maps, or an AI answer
Referral	Somebody told them about you
Social	Saw you on Facebook, Instagram, or similar
Repeat	Existing customer coming back
Other	Truck, sign, event, print, everything else

 

Track lead count, source, and whether it closed. Three columns. Five minutes a week.

Two honest complications to know about before you trust the data too much.

First, attribution is messy. Somebody who saw your posts for 4 months, got your name from a neighbor, then searched for you and called will say “Google.” All 3 things contributed. Don’t over-engineer this. Patterns over months matter more than precision on any single lead.

Second, referrals get undercounted as a marketing result and they shouldn’t be. If somebody refers you because your work is good, that’s operations. If somebody refers you because they saw your name in an email and remembered you exist, that’s marketing. The line is blurry, and it’s why I’d measure total inbound volume alongside source rather than treating each channel as a sealed box.

Judging Each Channel Fairly

Different channels pay off on different clocks, and comparing them at the same moment produces bad decisions.

Channel	When to Evaluate	What Good Looks Like
Paid ads	30 to 60 days	Cost per lead below your value per lead
Search visibility	4 to 6 months minimum	Rising inquiries from search, better quality calls
Email and follow-up	60 to 90 days	Quotes getting answered, repeat work returning
Social	6 months	Referrals mentioning you, name recognition locally

 

The most expensive mistake in this table is judging search on a 60 day window. The work in months 1 and 2 is largely invisible by design, and killing it at week 8 means paying for the slow part and quitting before the payoff.

The opposite error is letting ads run for a year without checking, because ads report quickly and there’s no excuse for not knowing.

The Number That Matters More Than Volume

Here’s where most ROI conversations stop short.

More leads is not the goal. Profitable leads are the goal, and those are different things.

Run your close rate and average job value by source. Most businesses find something like this: search inquiries close at 40% with an average job of $3,000, while a discount-driven channel produces triple the volume at a 12% close rate and $700 jobs.

The second channel looks better on a lead count report and is worse for your business. You’re spending your week on estimates that don’t close, for work that barely covers the trip.

So track quality alongside quantity:

• Close rate by source. Which channels send people who actually hire you?
• Average job value by source. Which send the bigger work?
• Time to close. Which produce people ready to move versus people who need 9 months?

If you’re trying to figure out how to attract high-quality clients for your service business, this is where the answer lives. Not in a technique, in your own data. Find the channel producing your best customers and fund it more heavily than the one producing the most noise.

Insider Tip from Rhonda: When somebody shows you a marketing report, look for the word “leads,” “calls,” or “inquiries.” If those words don’t appear anywhere, you’re being shown activity, not results. Activity is real work and it isn’t the thing you’re buying.

What to Do With What You Find

Four possible verdicts, and each has a clear next move.

Positive return, capacity available. Spend more. This is the rarest and happiest position.

Positive return, no capacity. Stop increasing spend and fix throughput or raise prices. More leads right now produce longer waits and worse reviews.

Unclear. Almost always a tracking problem rather than a performance problem. Fix the tracking, wait 90 days, look again. Don’t cancel anything on a hunch.

Negative return. Before cutting, check the sequence. Is the site converting? Does anybody follow up? Is response time under an hour? A channel producing leads that die after arrival isn’t a channel failure.

That last point matters, because the instinct when numbers look bad is to cancel the marketing. Sometimes correct. Often the leads were fine and something downstream was broken, and cancelling means the leaks stay while the traffic stops.

Doing This Regularly Is the Whole Point

Run these numbers monthly. It takes 10 minutes once tracking is in place.

Do it for 6 months and something shifts. You stop making decisions based on how busy the phone feels and start making them based on what actually produced work. That’s the difference between hoping and knowing, and it’s the foundation of any predictable client growth strategy worth the name. Predictability doesn’t come from finding the right tactic. It comes from knowing your numbers well enough to spot a problem in month 2 instead of month 8.

You’d never run the operations side of your business on a feeling. This side deserves the same treatment, and it’s less complicated than you’d think.

Four numbers. Ten minutes a month. Then the next time somebody asks how your marketing is going, you’ll have an actual answer.
