Which marketing numbers to track (and which to ignore)

The marketing numbers small businesses should track are the ones that connect to money: number of enquiries or leads, conversion rate (how many enquiries become customers), cost per lead, customer acquisition cost, average order value, customer lifetime value and return on marketing spend. Followers, likes and impressions are useful for diagnosing problems, but they don't tell you whether marketing is paying off. Pick a few key numbers, track them every month in one place, and use them to decide where to spend more and where to cut.

Many business owners feel unsure whether their marketing works. They see likes go up and down, but can't connect it to sales. That's usually a tracking problem, not a marketing problem. Once you measure the right things, decisions get much easier.

Vanity metrics vs business metrics

Vanity metrics aren't useless. If reach drops, fewer people see you, which will eventually affect enquiries. Use them to diagnose, not to judge success.

The key numbers explained

Leads or enquiries

A lead is anyone who shows real interest: a WhatsApp message asking for a price, a call, a form submission, a booking request. Count them every week, and note where each came from.

Conversion rate

Conversion rate is the share of leads (or website visitors) who become customers. If 100 people message you and 20 buy, your conversion rate is 20%. A low conversion rate usually points to slow replies, unclear prices, a weak offer or the wrong audience.

Cost per lead

Divide what you spent on a channel by the leads it brought. If you spent TZS 200,000 on ads and got 50 messages, each lead cost TZS 4,000. (Example figures only.)

Customer acquisition cost (CAC)

Divide total marketing spend by the number of new customers. This tells you what it costs to win one customer.

Average order value

Total revenue divided by number of orders. Raising it (with bundles, upsells or premium options) makes every customer more profitable.

Customer lifetime value (LTV)

How much a customer spends with you over the whole relationship. A salon client who visits monthly for three years is worth far more than her first visit. If lifetime value is high, you can afford to spend more to acquire customers.

Return on marketing spend

Revenue from marketing divided by what you spent. If a campaign cost TZS 500,000 and brought TZS 2,000,000 in sales, the return is four times the spend. (Example figures only.) Remember to consider profit, not just revenue.

Numbers to check for each channel

How to track where customers come from

• Ask every new customer "How did you hear about us?" and record the answer.
• Use different WhatsApp links with different pre-filled messages for each channel.
• Use unique discount codes for ads, influencers and SMS.
• Add tracking parameters (UTM tags) to links so Google Analytics shows the source.
• Set up conversion tracking in Google Ads and Meta Ads.
• Use separate phone numbers for big campaigns if calls matter a lot.

Build a simple monthly dashboard

You don't need fancy software. A spreadsheet with one row per month and columns for the key numbers works well. Fill it in at the start of each month for the month before. After three to six months you'll see trends and seasonality, and you'll know which channels deserve more budget. Our Google Analytics guide shows how to get website numbers.

What to do with the numbers

Numbers only help if they change decisions. If one channel brings customers cheaply, spend more there. If a channel costs a lot per customer, improve it or cut it. If leads are high but conversion is low, fix the sales process: reply faster, clarify prices, train staff. If conversion is good but leads are low, invest in more visibility. Review monthly and make one or two changes at a time, so you can see what made the difference.

Example: a salon's monthly numbers

Imagine a salon tracking its marketing for one month. It spent money on Instagram ads and printed flyers, and it keeps a simple tally of where each new client heard about it. The figures below are made up to show the method.

In this example, flyers cost much more per new client than Instagram ads. Google Maps and referrals bring clients for free, so the salon should invest time in reviews and referral rewards. Without tracking, the owner might have kept printing flyers because "they look professional".

Leading and lagging indicators

Some numbers tell you what already happened (lagging indicators), like revenue and new customers. Others hint at what's coming (leading indicators), like enquiries, website visits and email sign-ups. If leading indicators drop this month, sales may drop next month. Watch both.

Marketing words explained

Your plan for this week

1. Choose five numbers you'll track every month.
2. Start asking every new customer how they heard about you.
3. Create a simple spreadsheet with one row per month.
4. Fill in last month's numbers as best you can.
5. Set a reminder to update it on the first of every month.

Common measurement mistakes

• Tracking too many numbers, so nobody looks at any of them.
• Comparing one week with another instead of looking at monthly trends.
• Crediting the last channel a customer touched for everything, when several channels helped.
• Counting revenue but forgetting costs, so a busy campaign looks profitable when it isn't.
• Not writing down what changed each month, so you can't explain the numbers later.

Measurement doesn't have to be perfect to be useful. Roughly right numbers, checked every month, beat perfect numbers checked never. Pair this with Google Analytics for website data and your ad platforms for paid campaigns.

Start simple. Three numbers tracked every month (leads, new customers and cost per customer) will already change how you spend your marketing budget.
