Marketing KPI examples for small business

Most small companies measure marketing by glancing at their follower count now and then. That number looks good and tells you nothing. Good reporting fits on one screen, holds six numbers and can be built in a free spreadsheet. Below are the marketing KPI examples worth tracking in a small business, a one question test that exposes a vanity metric, and an honest note on what cannot be measured properly no matter who promises otherwise.

Key takeaways

• A KPI is a number that makes you do something differently. If it doubled tomorrow and you would change nothing, it is not a KPI, it is decoration.
• Six numbers are enough for a small business: enquiries, cost per enquiry, close rate, average deal value, cost to acquire a customer and the share of enquiries coming from referrals.
• The pressure to prove returns keeps rising. According to The CMO Survey from Duke Fuqua School of Business (spring 2025, 281 marketing leaders), 63 percent report stronger pressure from CFOs and 50 percent from board members, and they named demonstrating marketing's impact on financial results as their single biggest challenge.
• GA4, UTM parameters, a spreadsheet and one extra question on your enquiry form will do the job. A paid tool adds nothing until you have the data volume to justify it.
• Part of marketing cannot be measured precisely. Anyone claiming otherwise is either wrong or selling you software.

What is a KPI and how does it differ from a metric?

A KPI is a number you make decisions on. A metric is any number you can measure. The difference is consequence: when a KPI drops you change something, when an ordinary metric drops you simply note it.

In practice a KPI has to connect to money, or to a step that leads to money. Video views are not a KPI. The number of people who finished the video and then landed on your service page can be, because it tells you whether shooting another one is worth it.

Stick to three to six KPIs. With fifteen you track none of them properly and the report becomes a ritual nobody reads. On client projects we keep one sheet with six rows, and it is a document we genuinely come back to.

Which marketing KPI examples matter for a small business?

These six cover most companies selling services or higher priced products:

1. Enquiries per month. The most basic number. Forms, calls, messages.
2. Cost per enquiry. Your whole marketing spend divided by enquiries. Not just ads, the whole spend.
3. Close rate. What share of enquiries turn into work. Below ten percent the problem is usually who you are reaching, not how many.
4. Average deal value. Without it you cannot tell whether the enquiries are even worth having.
5. Cost to acquire a customer. Cost per enquiry divided by close rate. Compare it with the margin on an average deal and you instantly know whether marketing pays.
6. Share of enquiries from referrals. Few companies track this one, and it is the best available health check on your brand.

If you sell through an online shop, swap close rate for conversion rate and average deal value for average order value. The logic holds. Just remember to count content production into your cost per enquiry. We have written up what social media management costs so the calculation is not built on guesses.

How do you spot a vanity metric?

Ask one question: if this number doubled tomorrow, would I change anything? If the answer is no, it is a vanity metric. A follower who never buys, reach without a click, a view counted after three seconds.

We are not saying to throw those numbers away. They work as context when something breaks and you are looking for the reason. They must not be the headline number you judge marketing by.

An admission about our own reports. For years we put video views at the top, because it is a number that pleases and grows fast. It told the client nothing about whether the video paid for itself. Today enquiries sit at the top and views are somewhere near the bottom as supporting information. The reports are less impressive and far more useful.

How do you measure marketing without expensive tools?

Four things, all free or close to it:

• GA4 with conversions set up for form submissions and phone number clicks. Without a conversion, analytics is just a visit counter.
• UTM parameters on every link you post anywhere. Without them half your traffic lands in direct and you never learn what worked.
• One question on the enquiry form: how did you hear about us? Optional, one field. It will tell you more than any attribution model, especially for offline and referrals.
• A spreadsheet with one row per month. Six columns matching the KPIs above. It takes five minutes to fill in and after six months it shows a trend no dashboard will hand you.

Review monthly, not weekly. Weekly data in a small company jumps around enough to support any story you want, which tempts you into shifting budget based on noise. Then look at the quarter as a trend rather than at individual months.

What cannot be measured in marketing?

Anything that works slowly and across channels. Typically brand, image video, PR and offline. Someone sees your video on LinkedIn, does nothing, then four months later searches your name and writes to you. In analytics that shows up as organic search and the video gets no credit at all.

That is an uncomfortable admission for a studio that produces video. If we were being salesy we would tell you everything is measurable. It is not. What you can do is measure it indirectly: watch branded search volume in Search Console, the share of enquiries that arrive already knowing who you are, and the share of referrals. When those three rise, the brand is working even if attribution never shows it.

A practical rule: the shorter the path to purchase, the better it measures. Judge performance campaigns hard on enquiries and cost per customer. Judge brand work on a six month trend and accept that you will not get an exact figure.

Frequently asked questions

How many KPIs should a small business have?

Three to six. Fewer than three is too coarse, more than six and nobody tracks them regularly, so the report turns into a chore. When you want to add a seventh, first decide which one you are dropping.

How often should I review marketing?

Record numbers monthly, make decisions quarterly. The monthly entry gives you data, the quarterly view gives you a trend. The exception is a live paid campaign, which needs closer attention in its first two weeks.

Is follower count completely useless?

Not useless, just not a KPI. As context it works well: if you gain ten times the usual followers in a month and enquiries do not move, you know you attracted the wrong people. As the headline number in a report it misleads.

Is a paid analytics tool worth it?

Only once filling the spreadsheet by hand costs you more time than the tool costs money, which for a small business tends to start around hundreds of enquiries a month. Until then a paid tool gives you prettier charts of numbers you already have for free.
