three numbers that tell you if it is working.

marketing reporting has an inflation problem. the more numbers a report contains, the less likely any of them changes a decision. so here is the minimum set — three numbers that between them answer the only question that matters: is this channel worth more money next month or less?

— 01the three numbers.

none of them are platform metrics, which is the point. all three live at the intersection of marketing and sales, which is exactly where most reporting refuses to go.

that boundary is why so many reports are useless. the ad platform knows what it charged you and how many forms were submitted. it does not know which of those forms was a real buyer, and it never will unless someone connects the two systems. until that connection exists, every efficiency claim in your reporting is an assumption wearing a percentage sign.

you also want them in this order. cost per qualified enquiry tells you whether the top of the funnel is efficient. close rate tells you whether the enquiries are the right ones. payback tells you whether the whole thing is a business or a hobby. read them out of order and you will optimise for cheap leads that never close, which is the most common way a well-run ad account destroys value.

— 02how to calculate each one.

cost per qualified enquiry — total spend in the period, including fees, divided by enquiries your sales team would actually call back. the word qualified does the work: strip out spam, wrong-country and job applicants, and the number often doubles. that is the real one, and it is usually 30 to 50% worse than the number in your ad dashboard. that gap is not a failure of the campaign; it is the difference between a form submission and a buyer, and you cannot manage it until you measure it.

close rate — of those qualified enquiries, what share become customers. sales owns this, not marketing, but marketing quality changes it: better-targeted enquiries close higher, which is why cheap leads are often the expensive option. track it per channel rather than in aggregate — the channel with the worst cost per enquiry is quite often the one with the best close rate, and averaging the two hides the only interesting thing in the data.

payback period — how many months of a customer's revenue it takes to repay what you spent to acquire them. under three months, spend more. beyond twelve, fix the funnel before adding budget.

for subscription and repeat-purchase businesses, use lifetime value rather than first-order revenue here — otherwise you will starve a channel that acquires your best long-term customers because the first transaction looked unprofitable. for one-off, high-ticket purchases, first order is the honest input.

the number that changes the other two fastest is not a marketing number at all — it is how quickly sales responds. in the gulf especially, an enquiry answered within the hour closes at a materially different rate than one answered the next day. if your close rate is disappointing, check reply times before you rewrite a single ad.

— 03why reach and followers mislead.

they are inputs, not outcomes, and they are the easiest inputs to inflate. reach responds to volume and luck. followers respond to giveaways and trends. both can rise while enquiries fall, and frequently do — an account chasing broad attention drifts away from the audience that buys.

this is not an argument for ignoring them entirely. reach is a useful diagnostic when enquiries drop: it tells you whether the problem is distribution or conversion. it just is not a result.

the same applies to engagement rate. it is a ratio, so it falls as reach grows, which means a successful month can look like a decline. anyone reporting engagement rate as a headline is either not reading it or hoping you will not.

the one platform number worth keeping close is retention on video — how many people are still watching after three seconds and after fifteen. it does not prove revenue, but it is the earliest honest signal that the creative is working, and it moves weeks before enquiries do. treat it as a leading indicator and the three real numbers as the verdict.

— 04the one-line report.

the most useful monthly summary we send reads roughly: "spend x, qualified enquiries y, cost per enquiry z, up or down against last month, and here is the one thing we are changing." everything else — the graphs, the creative breakdowns, the platform detail — sits underneath for anyone who wants it.

if your current report cannot be compressed to that line, ask your agency to do it. the compression is the analysis.

one caveat worth stating plainly: none of the three work at low volume. if you get eight enquiries a month, monthly cost per enquiry will swing wildly on noise and you will be tempted to react to it. at that scale, read the numbers quarterly and use directional signals — reply times, saves, search impressions — to steer between reads. any growth marketing agency worth its fee will tell you which of the three numbers your volume can actually support.
