A small business notices, with satisfaction, that its follower count has doubled this year, or that a recent post was seen by thousands of people. The numbers are large, they have grown, and they feel like success.
But one question has not been asked: did any of it bring a single customer? Often, honestly examined, the answer is no — and the gap between the impressive number and that honest answer is what this article is about. This article, completing the measurement articles in this series, is about vanity metrics: the numbers that look good and mean nothing.
A note on sources is in order. Peer-reviewed research is cited by author and year and listed at the end; and a substantial part of what can be said about vanity metrics is practitioner consensus — the settled common practice of the field — rather than peer-reviewed research, and that is identified plainly wherever it is so.
What a vanity metric is
A vanity metric is a number that looks impressive and feels like success but does not connect to any genuine business outcome — a number that can be large, and can grow, while the business gains nothing real.
The measurement pillar in this series drew the underlying distinction, between activity measures and outcome measures. A vanity metric is an activity measure mistaken for — or presented as — a measure of success. It records something: an amount of attention, a count of followers, a quantity of views. What it does not record is whether any of that attention, those followers, those views became a genuine customer or a genuine pound of revenue.
The defining feature of a vanity metric is precisely this disconnection. It is not that the number is false; the follower count really did double, the post really was seen by thousands. It is that the number, true as it is, does not bear on the question that matters — whether the marketing is producing genuine business. A vanity metric is an accurate answer to a question a business should not be asking.
The term “vanity” is exact and worth dwelling on. These metrics serve vanity: they make a business feel good, look successful, and appear to be progressing. What they do not do is the actual job of a metric, which the measurement pillar defined as informing a decision. A vanity metric flatters; it does not inform.
It is worth being precise that the fault is not in the number’s existence but in its use as a measure of success. A follower count is a fact, and facts are not dishonest. It becomes a vanity metric when a business treats it as evidence that the marketing is working — when the number is asked to answer a question it cannot answer. The vanity is in the interpretation, not in the figure.
Why vanity metrics are so seductive
If vanity metrics mean so little, it is worth asking why businesses are so drawn to them — because the pull is genuine and strong, and the figure below sets out what produces it.
The figure’s central lesson is in its caption. Every one of the five pulls is real — vanity metrics genuinely do rise, flatter, and invite display — and not one of them has anything to do with whether the metric is worth watching. The seduction of a vanity metric is entirely separate from its value, which is precisely what makes it dangerous: a business is pulled toward it by forces that feel like reasons but are not.
The harm they actually do
It would be a mistake to think vanity metrics are merely useless — harmless numbers a business could watch or ignore without consequence. They do genuine harm, and the harm is worth setting out.
The first harm is false confidence. A business watching a rising vanity metric feels successful, feels its marketing is working, feels reassured — and that feeling can be entirely unearned. A business can watch its followers and impressions climb steadily while it wins no new customers and earns no new revenue, all the while believing, on the strength of the rising number, that things are going well. False confidence is dangerous because it removes the discomfort that would otherwise prompt a business to fix what is genuinely wrong.
The second harm is misdirected effort. A business that watches a vanity metric will, naturally, work to improve it — and effort spent growing a number that does not connect to genuine business is effort taken from work that would. The vanity metric does not merely fail to help; it actively pulls a business’s limited time and attention toward the wrong activity.
The third harm follows from the first two: a business steered by vanity metrics steers itself wrongly. The whole purpose of measurement, the pillar article argued, is to inform decisions — and a business informed by vanity metrics is informed falsely, and decides accordingly. It congratulates itself when it should worry, persists when it should change, and invests in the appearance of marketing rather than the substance. Vanity metrics are not neutral; a business would genuinely be better off measuring nothing than measuring these.
It is worth letting that last claim land, because it is a strong one and it is meant. A business that measures nothing at least knows it does not know, and retains the healthy unease that prompts honest questions. A business that measures vanity metrics believes it knows, wrongly, and loses that unease. The false map is more dangerous than no map, because the traveller with no map proceeds with caution and the traveller with a false one proceeds with confidence.
Vanity metrics and the reports you receive
A small business does not only encounter vanity metrics on its own dashboard; it encounters them in the reports it receives — from the platforms it uses, and from any agency or contractor handling its marketing — and these reports deserve a wary eye.
Such reports often lead with vanity metrics, and for an understandable reason. A report that opens with large, rising numbers — impressions reached, followers gained, posts viewed — looks like a report of success, and a party reporting on its own work has an interest in looking successful. The vanity metrics make the report flattering, both to the reporter and, by extension, to the business reading it.
This is not necessarily dishonesty; a report can lead with vanity metrics simply because those are the numbers the platforms make most readily available. But the effect is the same whatever the intent: a business reading such a report can come away reassured by numbers that, as this article has shown, do not bear on whether its marketing is genuinely working.
The defence is to read every report the way this article has taught — to look past the impressive opening figures and ask, of the report as a whole, what it says about genuine outcomes. A business receiving a marketing report should ask plainly: how many genuine enquiries and customers does this report account for, and at what cost? A report that cannot answer that, however many impressive numbers it contains, has not reported on what matters.
The common vanity metrics
It is worth naming the common vanity metrics specifically, and what each fails to tell a business, because they are easier to resist once seen plainly. The figure below sets them against the questions they leave unanswered.
The figure’s pattern is the whole of the lesson. In every row, the left column is a number that rises and reassures, and the right column is the genuine question that number cannot answer. A business looking at the left column sees progress; a business that asks the right column’s questions sees how little the progress amounts to. The common vanity metrics are common precisely because they are the numbers most easily mistaken for the outcomes they sit near.
The figure also shows why these particular numbers are the persistent ones. Each sits genuinely close to a real outcome — followers are near customers, page views are near enquiries, impressions are near genuine attention — close enough to be mistaken for it. A vanity metric is rarely a number with no relation at all to success; it is, more often, a number adjacent to success and standing in for it, which is exactly what makes the substitution so easy to miss.
The test: is this a vanity metric?
Rather than memorise a list of vanity metrics, a business is better served by a test it can apply to any number — because new metrics appear, and the same number can be a vanity metric in one use and a useful one in another.
The test is a short set of questions. Does this number connect, even indirectly, to genuine customers or revenue? Would a change in it actually change a decision the business makes? Could the number grow substantially without the business doing any better in genuine terms? And — a question the next section but one takes up — could the number simply be bought?
A number that connects to no genuine outcome, that would change no decision, that could grow while the business genuinely stood still, is a vanity metric, whatever it is called and however prominently it is displayed. A number that connects to genuine outcomes, that would change a real decision, that cannot rise unless the business is genuinely doing better, is a metric worth watching. The test sorts numbers by what they genuinely are, not by how they appear.
This test is the practical heart of the article. A business that applies it honestly to the numbers in front of it — on its analytics dashboard, in the reports it receives, in the figures it feels proud of — will find that it can tell the vanity metrics from the genuine ones reliably, and that a surprising number of the figures it had been watching fail.
The test is also durable in a way a list of named metrics is not. Particular metrics come and go, and a new flattering number can always be invented; but a number that connects to no outcome, changes no decision, grows emptily, and can be bought is a vanity metric whenever and wherever it appears. A business that holds the test holds a defence that does not go out of date.
How vanity metrics change what a business does
The harm of misdirected effort, named earlier, is worth examining more closely, because the way a vanity metric distorts a business’s behaviour is subtle and worth seeing in detail.
A business watching a metric does not merely observe it; it begins, naturally, to work to improve it. This is sound when the metric is a genuine outcome — working to increase enquiries means working to market better. It is corrosive when the metric is a vanity metric, because the business then works to improve a number that does not matter, and the work itself drifts away from what does.
The drift shows itself concretely. A business optimising for engagement begins to produce whatever earns engagement — which is often not what genuinely informs or attracts a customer. A business optimising for follower growth begins to chase followers, who may be a wholly different group from its genuine prospective customers. A business optimising for views begins to make whatever is widely viewed, whether or not it serves the business at all. In each case the vanity metric, by being the thing watched, becomes the thing pursued, and the pursuit reshapes the business’s actual work.
This is the deepest version of the misdirection harm. A vanity metric does not merely waste a glance; watched over time, it quietly steers a business’s content, its effort, and its judgement toward serving the metric rather than the business. What a business measures, it tends to become — and a business that measures vanity tends, slowly, to organise itself around producing vanity.
The honest nuance: diagnostic use versus goal
Fairness requires an honest qualification, because the argument so far, left unqualified, would be slightly too strong: the metrics called vanity metrics are not worthless in every possible use.
The measurement pillar made the relevant point: an activity measure near the top of the measurement chain can serve as a genuine early signal, a leading indicator, even though it is a poor measure of success. A sharp, sustained fall in website visits or in reach is worth noticing, because it may foretell a fall in customers. Used strictly in that diagnostic role — as an early-warning sign, watched lightly, as the handful article described its single leading indicator — an activity metric has a legitimate, limited place.
What makes a metric a vanity metric is not the number itself but the use: treating it as a goal, as a measure of success, as the thing the marketing is for. The same impressions figure is a mild, legitimate diagnostic signal when watched lightly as an early warning, and a vanity metric when a business sets out to grow it, congratulates itself when it rises, and mistakes it for evidence that the marketing is working.
So the honest position is precise. A business need not refuse ever to glance at an activity number; it must refuse to treat such a number as a goal or a measure of success. The fault is not in the metric’s existence but in the weight a business places on it — and the harm described earlier comes entirely from placing the wrong weight.
The practical line is therefore one of weight and intent, not of which numbers a business is permitted to see. A business may glance at an activity figure as an early-warning glance; it may not adopt it as a target, celebrate its rise, or report it as success. The same number, in other words, is harmless as a thermometer and harmful as a trophy.
Why a business reaches for them
Beyond the seductive qualities the figure set out, there is a deeper reason businesses reach for vanity metrics, and it is worth naming honestly, because naming it is part of resisting it.
A business reaches for vanity metrics, in part, because the genuine metrics are harder and less comfortable. The outcome metrics of the handful — enquiries, customers, the cost and worth of a customer — are harder to track, slower to move, and capable of delivering unwelcome news. The vanity metrics are easy, responsive, and almost always encouraging. Faced with a hard, honest measure and an easy, flattering one, a busy and anxious owner is humanly drawn to the second.
There is also a reason of effort. A vanity metric can usually be grown with relatively easy activity — posting more, gathering followers, generating impressions — while the genuine outcomes move only when the harder, deeper work succeeds. A business that wants to feel it is making progress, without doing the hard thing that genuine progress requires, will find vanity metrics obligingly available.
Naming this is not an accusation; it is a description of an entirely human tendency, and recognising it in oneself is the first defence against it. A business that understands it reaches for vanity metrics because they are easy and comfortable, not because they are useful, is a business already most of the way to setting them aside.
There is no shame in having reached for them. Nearly every business has, at some point, taken comfort in a vanity metric; the pull is genuine and the tools encourage it. What matters is not that a business once watched the wrong numbers but that, having seen them clearly, it chooses to watch the right ones instead. Recognition, not self-reproach, is what the section is for.
Vanity metrics can be bought
One feature of vanity metrics deserves a section of its own, because it exposes their emptiness more sharply than anything else: many of them can simply be bought.
Followers can be bought. Likes can be bought. Impressions and views and engagement can, through one means or another, be purchased outright. A business willing to spend a little can make several of its vanity metrics rise dramatically without doing anything genuine at all — without gaining a single real customer, without improving in any way that matters.
This points to something fundamental, and the economics of signalling make it precise. A measure is only meaningful as a signal of genuine quality if it is costly to produce falsely — if it cannot easily be faked by someone without the underlying quality (Spence, 1973). A vanity metric fails exactly this condition: because it can be bought, it can be high for a business that is genuinely doing nothing, which means a high value of it signals nothing reliable about genuine success.
The genuine metrics, by contrast, cannot be bought in this way. A business cannot purchase genuine customers who genuinely chose it, genuine revenue, a genuine relationship of trust. That a metric can be bought is therefore close to a definition of its emptiness: if a number can be high without the business being any good, the number does not measure whether the business is any good. The buyability of vanity metrics is not a separate problem; it is the clearest possible demonstration of what they are.
This also gives a business a sharp, practical question to put to any metric: if I wanted to, could I make this number rise sharply without winning a single genuine customer? If the answer is yes, the number is, by that fact alone, disqualified as a measure of success — whatever else might be said for it. The buyability test is quick to apply and remarkably reliable.
Vanity metrics in social media
Vanity metrics are found everywhere in marketing measurement, but they concentrate most thickly in one area, and it is worth addressing directly: social media.
Social media is, in a sense, built around vanity metrics. Followers, likes, shares, comments, reach, impressions — the numbers a social platform puts in front of a business are overwhelmingly the activity metrics this article has warned against, and they are presented prominently, updated constantly, and designed to feel rewarding. A business measuring its social media by the numbers the platform offers is measuring almost entirely by vanity metrics.
This does not mean social media is worthless for a small business; it means social media must be measured by the same honest standard as everything else. The genuine question is not how many followers a business has or how many people a post reached; it is whether the social media activity produces genuine enquiries and customers. A business with a large following that yields no genuine business is not succeeding at social media, however the platform’s numbers look.
The practical guidance is to hold social media to the outcome standard the measurement pillar set. A business should ask of its social media what it asks of every channel: are genuine customers coming from this, at a cost — in money or, more often, in time — worth what they are worth? Measured that way, social media takes its honest place among a business’s channels; measured by followers and likes, it becomes the purest theatre of vanity metrics there is.
None of this is a verdict that a small business should avoid social media; that is a separate question, turning on whether a business’s customers are genuinely reachable there. It is a verdict on how social media should be judged: by the genuine business it produces, not by the applause the platform counts. A business can use social media well — but only if it measures it honestly.
The deeper comfort they provide
Underneath everything this article has said lies one more truth about vanity metrics, and it is the most important: their deepest appeal is that they let a business avoid an uncomfortable question.
The uncomfortable question is the one the measurement pillar insisted on — is the marketing genuinely working, genuinely producing customers worth more than it costs? That question can have an unwelcome answer. A business that asks it honestly may find that its marketing is not working, that its effort and money are being wasted, that something it has invested in is failing. Asking the genuine question risks a genuinely difficult answer.
Vanity metrics offer an escape from that risk. They let a business feel measured, feel informed, feel that it is paying attention to how its marketing performs — while never confronting the question that could deliver bad news. They provide the comfort of measurement without its discomfort, the appearance of honest attention without the substance.
This is why resisting vanity metrics takes more than information; it takes a certain willingness. A business has to be willing to ask the genuine question and to hear the genuine answer, even when the answer may be unwelcome. The whole appeal of the vanity metric is that it spares a business that willingness — and the whole of resisting it is choosing the honest, sometimes uncomfortable measure over the flattering, always comfortable one.
This also explains why the argument of this article cannot be won by information alone. A business can fully understand that vanity metrics mean nothing and still reach for them, because the reaching is driven by the wish to avoid discomfort, not by a lack of knowledge. The genuine remedy is a decision — to want the truth about the marketing more than the comfort of not knowing it — and that decision, once made, is what makes the knowledge usable.
Genuine encouragement, and where it comes from
This article has been hard on vanity metrics, and fairness requires acknowledging the genuine human need they exploit — because a business does need encouragement, and pretending otherwise helps no one.
Running a small business is demanding and often uncertain, and an owner genuinely needs signs of progress to sustain the effort. Vanity metrics offer exactly that — visible, frequent, reassuring signs — and part of their grip is that the need they meet is real. A business told simply to ignore vanity metrics, with nothing offered in their place, is being told to give up a genuine source of encouragement.
But the encouragement vanity metrics give is false, and false encouragement is worse than none, because it sustains effort in the wrong direction. The genuine encouragement a business needs has to come from genuine sources — and those exist.
A real enquiry from a real prospective customer is encouragement. A new customer won is encouragement. A customer who returns, or who refers another, is encouragement. The handful of genuine metrics, watched over time and trending upward, is encouragement — and it is the real thing.
So the answer is not to forgo encouragement but to take it from the genuine outcomes rather than the empty numbers. A business that learns to feel genuine satisfaction in a real enquiry, a real customer, a real upward trend in the handful, has found an encouragement that is both sustaining and true — and has no further need of the flattering numbers that mean nothing.
How to resist vanity metrics
Drawing the article together, it is worth setting out plainly how a business resists vanity metrics in practice.
It resists them, first, by anchoring on the genuine outcome metrics — the handful the previous article described. A business whose attention is fixed on enquiries, customers, and the economics of winning them has, in that focus, the strongest possible defence against the vanity metrics, because its eye is already on the numbers that matter and the flattering ones are simply not on its list.
It resists them, second, by applying the test — does this connect to genuine outcomes, would it change a decision, could it grow while the business stood still, could it be bought? — to every number it is tempted to feel proud of. A business in the habit of running its impressive numbers through that test will catch the vanity metrics before they take hold.
And it resists them, third, by cultivating a deliberate suspicion of any number that only ever rises and always feels good. Genuine outcome metrics fluctuate, sometimes deliver bad news, and demand hard work to move; a number that climbs steadily and reassures unfailingly is, for that very reason, to be distrusted. A business that treats the comfortable number as the suspicious one, rather than the satisfying one, has internalised the whole lesson of this article.
It is worth adding that resisting vanity metrics is easier as a habit than as a series of individual efforts. A business that has, once, set up the handful of genuine metrics and fixed its attention there is not fighting the vanity metrics daily; it has simply arranged its attention so that the genuine numbers are what it sees. The strongest resistance is structural — building the right habit once — rather than a repeated act of will.
A practical approach
The article’s argument resolves into a practical approach, and the table below sets out the common vanity metrics, why they tempt, and what a business should do instead.
| The vanity metric | Why it tempts | What to watch instead |
|---|---|---|
| Followers | A large, rising count feels like an audience | Enquiries and customers the audience produces |
| Impressions and reach | Big numbers feel like being seen | Whether the seeing led to genuine contact |
| Page views | Traffic feels like interest | Whether visits become enquiries and customers |
| Likes and shares | Visible approval feels like success | Whether approval ever turns into business |
| Email list size | A growing list feels like a growing reach | Whether the list produces opens, replies, sales |
The approach, in short, is this: anchor attention on the genuine outcome metrics; run every impressive number through the test of whether it connects to real outcomes, would change a decision, could grow while the business stood still, or could simply be bought; allow an activity number a place only as a lightly-watched diagnostic, never as a goal; and treat the comfortable, ever-rising number with deliberate suspicion. A small business that does this will not be flattered by numbers that mean nothing — and will keep its attention, and its effort, on whether its marketing is genuinely working.
The whole of this approach can be held in a single habit of mind: when a number makes a business feel good, that is the moment to ask what it actually means. The good feeling is not a reason to trust the number; it is, if anything, a reason to examine it. A business that has learned to treat its own satisfaction with a figure as a prompt for scrutiny rather than a confirmation has built the soundest defence against vanity metrics there is.
Concluding remarks
A vanity metric is a number that looks impressive and feels like success but does not connect to any genuine business outcome. It is an activity measure mistaken for a measure of success — an accurate answer to a question a business should not be asking.
Vanity metrics are seductive for genuine reasons — they rise, they are easy to grow, they flatter, they are featured, they are easy to display — and not one of those reasons bears on whether they matter. They do real harm: false confidence that removes the discomfort which would prompt a fix, misdirected effort, and decisions steered wrongly. The common ones — followers, impressions, page views, likes, list size — each look like progress and each leave the genuine question unanswered.
A business is best served not by memorising a list but by a test: does the number connect to genuine outcomes, would it change a decision, could it grow while the business stood still, could it simply be bought? That last question is decisive, because a metric that can be bought cannot signal genuine success. The honest nuance is that an activity number has a limited, legitimate use as a lightly-watched early-warning signal; what makes a metric a vanity metric is treating it as a goal. And the deepest truth is that vanity metrics appeal because they spare a business the uncomfortable question of whether its marketing is genuinely working — which is exactly why resisting them takes not just knowledge but the willingness to ask that question and hear its answer.
This article completes the measurement articles in this series. The next articles turn to a closely related subject — why visitors a business has genuinely attracted so often leave without becoming customers.
Future developments
The warning against vanity metrics is durable, and it is worth saying why, because the durability is the reason the article is worth acting on.
The particular vanity metrics will change as the platforms change. New ones will appear — new counts, new scores, new forms of engagement, each freshly presented as meaningful. A business that had merely memorised today’s list of vanity metrics would be defenceless against tomorrow’s. But a business that has grasped the test — connection to genuine outcomes, capacity to change a decision, immunity to being grown emptily or bought — can apply it to any number the future presents, whatever it is called.
There is reason to think the temptation will, if anything, grow. As genuine measurement becomes harder — as the privacy changes the measurement articles described make real attribution more difficult — the easy, abundant vanity metrics become relatively more available and relatively more tempting. The gap between the comfortable number and the genuine one widens, and the discipline of preferring the genuine one becomes more demanding and more valuable.
For a small business the steady conclusion is to hold to the genuine outcomes and to the test, year after year, whatever new flattering numbers the platforms produce. A business that keeps its attention on whether its marketing genuinely produces customers — and that treats every comfortable, ever-rising number with the suspicion it deserves — has a defence against vanity metrics that does not expire. The numbers that look good and mean nothing will keep being offered; the business that knows them for what they are need not be misled by them.
