How to Measure Results on a Small Budget

Part of our series on growing your brand without a giant budget.

Only 25% of UK SMEs believe they have clearly defined marketing performance measures, according to a 2024 survey of almost 2,000 UK small business decision-makers by The Marketing Centre. That is not a budget problem. It is a clarity problem, and a genuinely fixable one, without hiring a data analyst or buying software you will open twice and forget about. Here is what to actually track, roughly in order of how cheap and quick each one is to set up.

Two different questions, not one

Every campaign is really being asked two different questions at once, and each one needs a different kind of measurement.

• Did this work right now? Activation measurement. Fast, direct, and usually cheap to set up: clicks, redemptions, footfall, calls, bookings.
• Is my brand getting stronger? Brand building measurement. Slower to show, harder to pin on a single week of activity, but the effect that tends to matter most over time.

As we set out in our post on The Long and the Short of It, most smaller advertisers only ever measure the first, simply because it is the easier one to track. That is a reasonable place to start, but if you never look at the second, you are only ever seeing half the picture, and potentially shortchanging your brand’s longevity.

Build measurement into the plan, not onto it afterwards

The cheapest, most reliable measurement tools are the ones agreed before a campaign goes live, not bolted on once someone asks how it went.

• Unique voucher or promo codes. A different code for each product promotion, publication or channel tells you exactly which one is driving redemptions, at no extra cost beyond setting it up.
• QR codes with real tracking. A QR code is only as useful as the link behind it. Tag every one with a proper UTM parameter identifying the source, medium and campaign, not just a bare URL.
• Dedicated phone numbers. A different number per channel, routed to the same team, shows you which one is actually generating calls.
• Unique landing pages. Sending each channel to its own page, or at least its own tracked URL, means your analytics can tell them apart without any guesswork.

None of this needs new software. It needs a five-minute conversation with your agency before the artwork is signed off, not a scramble to reconstruct it afterwards.

Ask your agency for a proper PCA

As we defined in our glossary of media jargon, a PCA, or Post Campaign Analysis, is the round-up of how a campaign actually performed against what was planned. It should be standard practice, not something you only receive when a client asks for it, or when something has gone wrong.

A proper PCA should tell you, in plain English:

• What was planned, and what actually ran, side by side
• Cost efficiency against the benchmarks agreed at the outset
• A channel-by-channel breakdown, not just a headline number
• What it means for the next campaign, not just what happened in the last one

Share of Search: a brand health check that costs nothing

Share of Search measures the proportion of category-related searches that mention your brand by name, tracked over time using free Google Trends data. It will not tell you why something changed, but it is a genuinely useful proxy for brand health when a full tracking study is out of reach: one widely cited study found the correlation between share of search and market share averaged 83% across countries and categories.

Check it quarterly, alongside whatever channel-level numbers you already track, and you have an early warning system for whether your brand is actually growing, not just whether last month’s campaign converted.

Brand lift studies

Brand lift studies go a step further, and are worth knowing about even if you are not ready to run one yet. As we defined in our glossary of media jargon, a brand lift study surveys people who saw your ad against a matched group who did not, before and after a campaign, to measure the actual shift in awareness, recall, consideration or favourability your advertising caused, rather than inferring it from search trends. Commissioning one independently is expensive, but the major platforms build a lighter version in for free once you clear a minimum spend: Google includes Brand Lift measurement on YouTube campaigns from roughly $5,000 in media spend, and Meta’s equivalent typically kicks in from around $30,000, since proving your ads worked is also in the platform’s own interest. Below those thresholds a study usually will not have enough people in it to separate a real shift from noise, so treat it as a marker for when your spend on a single platform grows, not something to force early.

For a more brand-specific view than search trends, without waiting to hit a platform’s spend threshold, a couple of self-serve tools are built for exactly this budget. YouGov BrandIndex Lite gives a free snapshot of brand buzz and how you compare with named competitors, a lighter version of the full enterprise BrandIndex product that otherwise runs into the tens of thousands a year. Attest is a paid but genuinely accessible option beyond that: a self-serve survey platform with its own consumer panel, priced per response rather than per project, so you can run a focused brand tracking survey on your own terms rather than commissioning a bespoke study.

A smaller-scale test and control

Bigger advertisers run matched market tests: the same activity live in one region and dark in a comparable one, so the difference between them shows the real, incremental effect. You do not need a national footprint to borrow the logic. Running a channel in one area or time window, and deliberately leaving it dark somewhere genuinely comparable, gives you a rough but honest read on whether that channel or specific creative is pulling its weight.

It only works if the comparison is fair: similar audience, similar time period, and long enough to see past the noise of an ordinary week. A month is a sensible minimum.

Incrementality and basic attribution

Two more ideas worth understanding before econometrics, since they explain why the numbers above can mislead you if read on their own.

Incrementality asks whether a campaign is genuinely driving new sales or leads, or simply taking credit for ones that would have happened anyway. As we defined in our glossary of media jargon, it is the difference between capturing demand and creating it. The test and control approach above is really a simple incrementality test: the gap between your live area and your dark one is the incremental effect, everything else is demand you would have captured regardless. This can also be applied across channels.

Attribution is the separate question of which channel gets the credit when someone converts, and it is trickier than it sounds. Most customers see several ads across several channels before they buy, and channel-level tracking, clicks, last-touch platforms and so on, tend to hand almost all the credit to whichever channel had the final click, usually search or a website visit. That systematically undercounts channels that build awareness rather than capture it: nobody clicks a poster or a radio ad, but it can be exactly what sent someone looking in the first place.

The cheapest fix is also the most reliable one for channels with no click to track: ask. A simple “How did you hear about us?” question, on a booking form, at the till, or in a post-purchase email, catches routes to purchase no dashboard ever will, and costs nothing beyond adding the question.

When you are ready for econometrics

Econometric modelling, sometimes called marketing mix modelling, is used for separating out what each channel actually contributed and to predict where to invest next to improve activity results. It is also usually out of reach until budgets are more substantial, since it needs a reasonable volume of historical data and specialist analysis to be worth the cost.

If you are not there yet, the IPA has published practical guidance on demonstrating effectiveness without one, built for exactly this situation: businesses with a real story to tell about what their marketing achieved, but not the budget for a full econometric model yet.

Your measurement checklist

Run through this before your next campaign goes live, not after it ends.

• A unique code, tracked link or number agreed for every channel, before launch
• A clear view of which numbers answer “did this work now” and which answer “is the brand getting stronger”
• A PCA booked in as standard, not just requested when something looks off
• Share of Search checked quarterly as a free brand health signal
• A test and control comparison considered for any channel you are unsure about
• A realistic view of when econometrics becomes worth the investment, not before

Want a PCA that actually tells you something?
