Most business owners are going by vibes
The number of business owners running their digital marketing on gut feel is astounding. Many don't know the answers to these basic questions:
What's your cost per click?
What does it cost you to acquire a customer?
What's a customer worth to you over the life of the relationship?
How many leads came in last month?
But I understand why. If nobody hands you the data, you can't know what's working.
And a lot of the time nobody does.
The ad platforms bury it. The agencies and freelancers either don't track it or don't share it.
So the owner ends up judging a campaign the way you'd judge a restaurant from the parking lot. It feels busy, or it feels dead, and that feeling becomes the verdict.
That's how marketing gets cut the moment money gets tight, and it's how good marketing gets killed right before it starts to pay.
So here's how we think about measurement at 9/8 Central, built from fourteen years of running campaigns for service-based businesses and watching which numbers actually predicted a sale.
The three digital marketing KPIs that matter: CAC, LTV, and ROAS
Here's the simplest way to frame the whole question. Your ads and your content are a machine that is supposed to turn dollars into more dollars. You put one dollar in the top. How many come out the bottom?
Every metric worth tracking is really a way of answering that question. The three that matter most:
Customer acquisition cost (CAC). How many dollars do you have to spend in ads before one person becomes a customer? If you spent $5,000 last month and closed 50 new customers from it, your CAC is $100.
Lifetime value (LTV). How much does a customer typically spend with you, across the first sale and every sale after it, for as long as the relationship lasts? For some businesses that's a single $400 job. For others it's a $1,000 engagement that renews for years.
Return on ad spend (ROAS). Put the first two together. If a customer costs you $100 to acquire and is worth $1,000 over the relationship, every dollar into the machine produces ten dollars out. That's a 10x ROAS, and it's the number that tells you whether to feed the machine more or shut it off.
You can have a dashboard full of pretty numbers. Impressions, reach, click-through rate, engagement.
None of them matter if they aren't translating into sales.
The ultimate metric is dollars in the pocket, and CAC, LTV, and ROAS are the three numbers that connect your marketing spend to it.
If you can't fill in those three numbers for your business today, that's the first thing to fix. Everything else in this post is built on them.
Count your at-bats
Dollars are the final score, but they're a lagging number. You usually can't see them move for weeks or months. So the number I watch most closely in between is leads. Opportunities. Or as I like to call them, "at-bats."
The more times you get to swing, the more likely you are to get a base hit or a home run.
Marketing's job is to put your sales team at the plate as often as possible. So the question for every ad and every piece of content is simple: is this generating an opportunity for the people who close business to do what they do best?
What counts as an at-bat depends on what you sell.
For a car dealership, it's someone walking onto the lot.
For a professional services firm, it's a meeting request.
For a product company, it's a quote inquiry or a demo request.
For some businesses, it's someone spending four or five minutes reading a specific page on the website, because that behavior reliably comes before a call.
Figure out what your at-bat is, define it precisely, and track it monthly.
Leads generated per month is the single most useful number between ad spend and revenue, because it tells you whether the top of the machine is working while you wait on the bottom.
How to measure marketing ROI: tie real sales back to the ads that caused them
The reason most owners can't fill in their CAC and ROAS is that they're missing the connection between a sale and the marketing that produced it.
The ad platform tells you about clicks.
Your CRM tells you about customers.
Nobody connects the two.
We do, and it's one of the biggest reasons our clients can make decisions with confidence.
Our system identifies who is on a client's website and links the names, addresses, and phone numbers from actual closed sales back to the people who saw the ads and visited the site. It's called a matchback, and it does two things.
First, when someone buys, we can trace the journey that got them there. Which ad they saw, which page they read, how long it took. That tells us which parts of the machine are producing revenue and which parts are just producing activity.
Second, for the people who visited but haven't bought yet, we know who they are and what they looked at. So we can serve them ads for the exact thing they were already researching.
That's really what sales is. It's finding someone who already has the problem and offering them the solution they're already looking for.
If I have to convince you that you have a problem, I'm fighting uphill the whole way.
If you already have the problem, convincing you is simple.
Contrast that with a client who came to us running traditional TV spots. There was no way to know what that spend was doing. Impressions, maybe. Sales, no. Once we moved the budget to digital with matchback in place, they could see exactly how many people saw an ad, what those people did afterward, and which of them became customers.
If your agency doesn't offer this, you're being asked to trust the machine without ever seeing what comes out the other side.
How to measure organic social media and YouTube
Ads are transactional. A dollar in, a dollar out, and you can measure the exchange.
Organic social media and YouTube are harder. Someone watches six of your videos over four months, then calls you, and nothing in the analytics connects the dots. The results are real, but they're hidden unless the customer tells you.
So you have to work a little harder to see them. Three things we do:
Track every link. Every link from a social post to your website gets a tracking tag, so when someone clicks through, you know which post sent them. Pair that with matchback and you can see which content started a journey that ended in a sale.
Ask every customer. Add one question to your intake: how did you hear about us? Then listen for people who mention your content. If nobody ever does, that's information too.
Watch the numbers that predict buying, not the ones that feel good. Likes and comments are vanity metrics. They make you feel good and rarely put dollars in the door. We pay more attention to follower growth, because it's a measure of people choosing to hear from you again. On YouTube, the number we care about most is watch time. How long does someone sit with your video? A person who watches eight minutes of you explaining their problem is far closer to a purchase than a hundred people who tapped a heart.
The mistake owners make with organic is judging it by the size of the audience. Small channel, few likes, minimal comments, must be failing. That's wrong, and the next example is why.
A small channel that landed Amazon
One of our clients sells a service to other businesses. Their YouTube channel is small. If you judged it by subscriber count or by the likes on any given video, you'd assume it's unsuccessful.
That channel has brought them Amazon, Tesla, Starbucks, and an NFL team.
We help them produce a podcast on a consistent schedule, edit it down, and post it to YouTube.
The content does two things and only two things.
It teaches.
And it tells stories.
When a buyer at a large company has a problem and goes looking for someone who understands it, they search YouTube. The algorithm serves up a video of someone explaining exactly their situation. They watch the whole thing. Then they reach out.
There's no viral moment. No big follower count.
But that's what organic is supposed to do, and it's why watch time and consistency tell you more about whether it's working than any applause metric ever will.
How long does it take for digital marketing to work?
Here's the hard truth we tell every client before they sign with us. Organic content takes time, and most people quit right before it gets good.
The pattern we've seen over and over:
It takes about three months for your friends to notice you're posting.
Six months for your network to notice.
Nine months for strangers to start finding you.
And it's often close to a year before you see real fruit.
Social media is a flywheel that starts spinning after sustained and focused effort.
So what should you measure during those first months, before the dollars arrive? Effort.
That sounds like a cop-out, so let me be specific about what effort means.
Are you putting out three to five posts a week, every week, with no down weeks?
Is each post actually helpful to the person you want to buy from you, meaning it teaches them something or tells them a story they'd care about? Or is it filler you shipped to hit a quota?
Is the content aimed at the people most likely to buy, or at whoever happens to be scrolling?
Organic content works the way sales works. A salesperson doesn't close on the first call, and they don't judge the week by the first call either. They judge it by whether they made the calls.
Consistent, correct activity compounds.
Every good post makes the next one more likely to land, because the audience is building underneath you even when the like count isn't.
If the effort is there and the content is right, hold the line through month six.
If the effort isn't there, no metric will save you. Fix that before you blame the strategy.
This is also the mistake that makes me wince most. Money gets tight, the owner looks at the organic numbers, sees nothing dramatic, and cuts it. They had just paid for the hardest part of the flywheel and walked away before it paid them back.
Is your marketing agency doing a good job? Ask this one question
If you're working with an agency, a freelancer, or an employee on your marketing, ask them this: what does winning look like?
Before we create a single piece of content for a client, we agree on the answer to that question.
The client has expectations. We have expectations.
If we can't both say out loud what success is, then six months from now neither of us will be able to tell the other whether we're winning. We'll be arguing about feelings instead of looking at a number.
A healthy answer sounds specific.
It names the at-bat and a monthly target for it.
It names the CAC or ROAS we're aiming for on paid.
It names the posting cadence and the watch time or follower growth we expect from organic.
It's tied to a year-long plan, because good marketing has a story arc with a beginning, a middle, and an end, and it can't be invented fresh each month based on what feels right.
A red-flag answer is vague, reactive, or built entirely on reach and engagement.
And here's the test that settles it: if you have to ask your agency whether your marketing is working, the exercise of defining success never happened. That's your answer. Find someone who knows how to put the work in at the beginning.
Start here
If you do one thing after reading this, know your numbers. Sit down this week and write down what you can.
If you're running ads:
cost per click
customer acquisition cost
lifetime value
ROAS
If you're doing social:
how many posts went out each of the last eight weeks
whether any weeks were skipped
whether followers are going up or down
and whether a single customer has mentioned your content as a reason they called
Anything you can't fill in is a gap to close, either with your own tracking or with the people you're paying to run this for you.
Then do one more thing.
Pull up your last ten posts and watch them as a stranger would. Scrolling, half-interested, thumb hovering. Would you stop? Would you watch to the end? Would you follow this account?
Be honest. Many owners, when they're honest, say no, because most business content is unhelpful, poorly produced, and disorganized in ways the business itself would never tolerate from someone else.
That question is revealing for organic.
Teach and tell stories, make something you'd actually watch, do it every week for a year, and track whether the right people are finding it.
For paid, feed the machine, measure what comes out the bottom, and tie every sale back to the ad that started it.
Do those two things and you'll never have to ask whether your marketing is working. You'll know.
Frequently asked questions
What are the most important digital marketing metrics to track?
Dollars in the pocket. Every other number is a proxy for it. The three that connect spend to revenue most directly are customer acquisition cost, lifetime value, and return on ad spend. If you can only track one thing in between, track leads, because at-bats are what turn into sales.
How long does it take for social media marketing to work?
For paid ads, you can read early signals in weeks, because the exchange is transactional and the data is immediate. For organic content, give it a year. Expect roughly three months before friends notice, six before your network does, nine before strangers find you. Judging organic at month three is like judging a garden the week after planting.
Are likes and comments important for a business?
They're vanity metrics. They feel good and rarely correlate with revenue. Follower growth is a better signal because it measures people choosing to hear from you again. On YouTube, watch time matters most. A viewer who sits through eight minutes of your content is far more valuable than a hundred who tapped a heart and kept scrolling.
How do I measure organic social media success?
Tag every link from social to your website so you know which post sent a visitor. Ask every new customer how they heard about you and listen for mentions of your content. Track your own consistency, because three to five real posts a week with no down weeks is the leading indicator of everything else. And if your agency can run matchbacks, you can connect tracked clicks all the way to closed deals.
What is a matchback?
It's the process of linking the names, addresses, and phone numbers from your actual sales back to the people who saw your ads and visited your website. It tells you which marketing produced which customers, and it lets you retarget the people who visited but haven't bought yet with the exact thing they were researching. We run matchbacks for every ad client at 9/8 Central, our digital marketing agency in Greenville, SC. Most agencies don't.
How do I know if my marketing agency is doing a good job?
Look at the report they send you and ask whether it answers the question you agreed on before the work started. If it's full of impressions and reach and you still can't say whether you're winning, the definition of success was never set. Ask what winning looks like. If the answer is vague, that's your answer.
Should I cut marketing when cash gets tight?
Cut the parts you can prove aren't producing, which is exactly why you need the numbers in this post. Be very careful cutting organic content in a downturn. Its results are often hidden, and quitting at month four or five means you paid for the hardest part of the flywheel and walked away before it paid you back.
What questions should I ask a digital marketing agency?
Ask how they'll define success with you before any content is made. Ask what numbers they report and how those connect to revenue. Ask whether they can trace a sale back to the ad or post that started it. Ask for the year-long plan. If they lead with reach and engagement and can't speak to CAC, LTV, or ROAS, keep looking.
How much content do I actually need to post?
Three to five posts a week, consistently, with no skipped weeks. Every one of them should teach or tell a story your ideal customer would care about. Filler posted to hit a number is worse than nothing, because it trains your audience to scroll past you.
