You’re staring at the ad account, or the spreadsheet with last month’s numbers pulled together the night before a board meeting, and you can’t answer the question with any confidence: is this money coming back? You know what was spent. You know some of it sold. Whether the two are connected is a separate question, and it’s one most reporting is built to help you avoid asking. Nobody sat you down and explained what to check, so you check what’s easiest to find, and what’s easiest to find is not what matters. Most founders in this position aren’t short on data. They’re short on the one or two figures that would settle the question, buried under a ton that won’t. This piece is that check, the one you can run yourself before you decide whether to bring someone else in for a closer look.
The metrics that actually tell you something
Two numbers decide whether marketing is working: what it costs you to win a customer, and what that customer is worth once they’ve bought. Put those two together, and you have an honest answer. Look at either one alone, and you have a guess at best. Most businesses we work with have detailed numbers for what they spend and vague numbers for what it returns, so cost per acquisition gets calculated but customer lifetime value doesn’t, and without both figures a channel that looks busy can be losing money while a channel nobody mentions at the meeting is the most profitable thing in the business.
A paid social account spending £3,000 a month and bringing in customers worth £40 each over their lifetime isn’t working, whatever the click-through rate suggests. An email flow costing almost nothing and bringing in repeat customers worth £300 each is doing the heavy lifting, even if nobody’s mentioned it in months. SEO tends to sit somewhere in between, slow to show a number worth reporting, easy to under-value because it doesn’t have a spend line next to it demanding attention, and often the channel with the strongest return once you work out what it would cost to replace with paid traffic. None of this shows up if you’re only checking whether the numbers went up this month compared to last, or comparing this month to a target that was never tied to a customer’s real value in the first place.
The metrics that quietly lie to you
Impressions, reach, follower growth, traffic with no sense of what that traffic did next: these numbers get relied on because they are easy to report and they almost always go up. A dashboard full of green arrows feels like progress, and that feeling is the problem, because none of those figures tell you whether a single one of those people bought anything. Reach measures how many people saw something. It says nothing about whether they cared, and even less about whether they paid.
These numbers stick around because they’re comfortable. A follower count climbing week on week gives everyone in the room something to nod at, and nobody has to sit with the harder question of whether the account behind those followers is bringing in any money. Traffic works the same way. A spike in visitors looks like success right up until you check how many of them bought anything, and by then the report’s already been sent. A high open rate on an email that generated no sales tells the same story: engagement without outcome, reported as though the two were the same thing. Treat these figures as background, worth a glance, but never as the answer to whether your marketing is working.
What working should look like month to month
A healthy pattern is less exciting than a growth chart and far more reliable. Spend that can be traced to revenue, so if someone outside marketing asked where last month’s £4,000 went and what it brought back, you could answer in a sentence rather than a shrug. A channel mix that’s been tested rather than assumed, where paid social earns its budget on results rather than habit, and where a different performer like email or SEO gets credit for the sales it drives. Reporting built to hold up under a harder question, not built to look busy for a founder too stretched to ask one. Nothing on the report should need a caveat before you’d feel comfortable showing it to someone outside the business.
Businesses that audit their marketing on a regular basis are 313% more likely to succeed, according to research cited by Citric Media and drawn from Smart Insights data. That gap is worth thinking about. It isn’t a case of successful businesses having more time to check their numbers because they’re doing well. Checking their numbers is part of why they’re doing well. Marketing that earns its place gets checked. Marketing that just runs gets left alone, and left alone is where the waste tends to sit.
When the honest answer is “we don’t know”
If you’ve read this far and you’re still not certain, that’s common, and it’s fixable, not a sign you’ve done something wrong. Most founders running £500k to £2m a year haven’t had the time or the outside view to build proper attribution into their reporting, because they’ve been busy running the business the reporting is meant to serve.
A quick self-check gets you part of the way there. It won’t untangle overlapping channels, spot the sale your paid social took credit for that would have happened anyway through search, or build a plan for what to do with the budget once you know where it’s going. That takes a proper look from someone with no financial stake in the answer, which is what a proper marketing audit is built to give you.
Our audit is a fixed fee, not a percentage of anything, and it ends with a prioritised 90-day plan you can act on straight away, not a deck that gets filed away. If you move into a retainer afterward, that fee comes off your first month, so a straight answer never costs you twice. If you’re ready to stop guessing and start knowing, that’s the conversation worth having next, and once you’ve got a clear answer, the next question is what you should be spending in the first place.
