How to Tell Which of Your Marketing Is Actually Working

Not knowing has one specific and expensive consequence: it makes cutting anything feel like a gamble.

The shrug

Somebody asks where your customers come from, and the honest answer is a shrug, or the catch-all: word of mouth, mostly.

Meanwhile you are paying for several things at once — ads, an agency, a directory listing, a subscription somebody set up two years ago — and you could not rank them by what they return. You have considered cutting one. You have not, because you could not prove it was the right one to cut.

Uncertainty always defaults to spending

This is the mechanism worth understanding, because it explains why the problem persists for years rather than months.

If you cannot prove which channel produced customers, then cancelling any of them might be cancelling the one that works. So the safest available decision is to keep paying for everything, permanently. Not because anybody decided that was optimal, but because it is the only choice that cannot be blamed afterwards for a bad quarter.

The same blindness stops you scaling what does work. You cannot distinguish the channel that produced a good month from the channel that merely coincided with it, so you cannot confidently put more money behind either.

This is the problem that hides all the others

Every other way a business loses customers — missed calls, wasted ad spend, a site that loses people — is invisible without measurement.

You cannot fix what you cannot see. More importantly, you cannot tell which of them is your biggest problem, so attention goes to whichever one somebody mentioned most recently. That is almost never the same as the one costing you the most.

What actually needs to exist

Analytics that records enquiries, not just visits. Most setups count pageviews and stop there. A form submission and a phone tap are the events that matter, and the majority of small business analytics records neither — which means the reporting describes browsing behaviour rather than business outcomes.

Calls tracked as well as forms. For most local service businesses the phone is the primary channel and the least measured. If calls are not counted, your data describes a minority of your customers and quietly misleads you about the rest. A tap on a phone number is a trackable event and almost nobody sets it up.

Source connected to outcome. Not which channel produced the visit — which produced the enquiry. Those are different numbers and the gap between them is exactly where budget goes to die. A channel can send plenty of traffic and produce nothing, and on a pageview-only report it will look like your best performer.

One page you will actually read. A short monthly summary in plain language: enquiries, where they came from, what each cost. A dashboard nobody opens is not measurement, it is furniture.

The order to build it in

Analytics and conversion tracking first, and verified with a real submission rather than assumed to work. This matters more than it sounds: tracking that reports success while recording nothing is worse than no tracking, because it produces confident wrong answers.

Call tracking second, live within about a week.

Then wait. The first genuinely clean month of data takes four to six weeks, and reading three days of data will mislead you badly.

What it costs

This is the cheapest item on any marketing list by a wide margin — a few hours of setup, once — and it is the one that makes every subsequent decision about money better.

It is also, almost always, the one that gets postponed. Unlike a new website or a campaign, nobody can see it from the outside. There is nothing to show anybody. That is precisely why it keeps getting pushed behind things that are more visible and less useful.

One warning about what you will find

The first month of real data usually contains at least one unwelcome surprise. A channel somebody has defended for years turns out to produce almost nothing. A channel nobody rates turns out to produce most of the enquiries. Occasionally the surprise is that a form has been broken for months.

That is not a reason to avoid measuring. It is the entire return on it — and if you already suspect which channel the bad news will land on, that suspicion is itself worth testing rather than carrying around indefinitely.

What a useful monthly report contains

Four numbers and a sentence. Enquiries this month. Where they came from. What each cost. How that compares with last month. Then one sentence on what you are changing as a result.

Anything longer is usually padding, and padding in a marketing report is generally there to obscure the fact that the four numbers are not good. If your current report runs to fourteen pages and you still cannot answer what an enquiry costs, that is the diagnosis.

Start with one channel, not all of them

If setting all of this up at once feels like a project you will postpone, pick the channel you spend the most on and instrument only that. One channel measured properly is worth more than five channels measured badly, and it gives you a working comparison for everything you add afterwards.

In practice that is almost always paid ads, because it is the one with a monthly invoice attached. Being able to say what an ad enquiry costs, with confidence, changes the budget conversation immediately — and it is usually the shortest route to either spending less or spending more with a reason.
