Marketing Measurement: The Right KPIs and Vanity Metrics
Instead of vanity metrics like likes and impressions, which marketing KPIs should actually be tracked; how to build measurement that feeds real decisions.

Short answer
A vanity metric is a number that looks good but never changes a business decision; likes, impressions and follower growth fall into this category because none of them connect directly to a sale or a new customer. A proper KPI, by contrast, is a metric tied directly to a business outcome, one that changes a decision when it moves up or down.
Most small business reports lead with likes and impressions because these numbers almost always grow and feel good; but that growth can come from ad spend just as easily as from genuine demand, and the two are impossible to tell apart from the number alone. Choosing the right KPI starts with finding which number actually changes a decision.
This piece covers the difference between a vanity metric and a proper KPI, and which metrics a business should actually be tracking.
Why a vanity metric misleads
A metric is a vanity metric if a concrete business decision does not change when it moves. If impressions double but sales do not, that metric may just be a sign of higher spend, not marketing success.
For a car dealership, Instagram follower count doubled over a year while showroom appointments stayed flat; follower growth looked good in the report but never fed a single sales decision. Metrics like this do not need to be dropped entirely, but they should not be used as a decision point.
How to choose the right KPI
The right KPI is built working backwards from the business goal: first identify which action actually generates revenue (a sale, an appointment, a form), then choose the KPIs that feed that action as intermediate steps. For an umrah and hajj tour operator, the real KPI is the number of genuine enquiries coming through WhatsApp, not page views.
Intermediate steps can be KPIs too, but only when their link to the final action is known. A landing page visit can be a KPI, but only if the rate at which that visit turns into a form fill is also tracked.
Which KPIs to track by channel
Every channel has its own suitable KPI set; measuring all of them by the same yardstick gives a misleading picture.
- Search ads: cost per conversion, conversion rate
- Social ads: cost per conversion, actual booking or order count
- Organic social: save and share rate (a stronger intent signal than likes)
- Email: not open rate, but the genuine action taken after a click
- SEO: not ranking position, but the conversions that ranking actually brings in
How GA4 key events feed KPI choice
Actions marked as key events in GA4 form the technical foundation of KPI selection; without a correctly defined key event, it is hard to see which traffic is actually valuable. For a residential property management firm, marking 'quote request form submission' rather than 'contact form submission' as the key event made it clear, for the first time, which content was actually generating demand.
Reports built without this clarity show which channel brings the most traffic, not which channel actually works; those are not the same thing.
How to keep a report simple
A good marketing report holds three to five KPIs, not fifteen; anything more does not get read and does not produce a decision. Every KPI needs a comparison against the previous period and a short line explaining what it actually means; a number on its own carries no meaning.
Who the report is actually for
The same report needs a different depth for the business owner and for the marketing manager; the owner wants a summary of three KPIs, the manager needs channel-level detail. Presenting one report in the same format to everyone either overwhelms the owner or leaves the manager without enough detail.
For a residential property management firm, the owner got a one-page monthly summary while the operations team got a weekly channel-by-channel table; both came from the same data but fed different decisions.
When to revise KPI targets
A KPI target should not be set once and left fixed forever; when market conditions, budget or the service offering change, the target needs a second look too.
For a car dealership, the cost-per-appointment target was raised temporarily after a new model launch, because awareness costs ran higher in that early period; a few months later the target was brought back down to its previous level.
Never changing a target means ignoring changing conditions; changing it every month makes the KPI lose its meaning. The right approach is a review every quarter.
A revised target needs to be communicated clearly to the team; a target changed quietly can leave the team still making decisions against the old number.
Marketing measurement is not about collecting numbers that look good; it is about finding the few KPIs that genuinely feed a business decision and tracking them consistently. Likes and impressions can stay in the report, but they should never be the decision point. If you would like your own report simplified around the right KPIs, a discovery call is a good place to start.
FAQ
Does like count matter at all?
Not entirely irrelevant, but it does not change a decision on its own; it can be an awareness signal, but it is not directly tied to sales.
Is there one KPI list that fits every business?
No single list exists; KPIs should be built around whichever action actually generates revenue for that business, a sale, a booking, a form.
Can the right KPI be chosen without GA4?
It is difficult; without a defined key event, it becomes hard to tell which traffic is genuinely valuable.
How many metrics should a report contain?
Three to five KPIs is usually enough; more than that turns the report into a list that does not produce a decision.
