In many Swiss SMEs, the annual marketing review doesn't really exist. There's an accounting summary, a budget rolled over from one year to the next, and a vague feeling that things are "working" or "working less well than before." Then January arrives, and decisions get made on instinct.
Yet a serious marketing review requires neither three weeks of consulting nor a dashboard with forty metrics. It requires two hours, ten numbers and three decisions. Here is a simple method to close out 2026 properly and enter 2027 with a plan rather than a hunch.
Why two hours are enough
A review is not an audit. An audit sets out to explain why things work: that takes weeks. A review simply establishes what worked, and makes the call: that takes discipline. Confusing the two is the number one reason the exercise never gets done.
The rule that protects your time: you open four sources only — your accounts, Google Analytics 4, Google Search Console and your advertising platforms. Anything that isn't in those four sources doesn't go into this year's review. You note it down for next year, in a line labelled "to be measured in 2027."
Setting the table: 10 minutes
Open a spreadsheet with three columns: Metric, 2026, 2025. That comparison column is what turns a number into information. A site with 12,000 visitors says nothing; 12,000 visitors against 8,400 the year before is +43% and a decision waiting to be made.
Then fix the period: 1 January to 31 December 2026, compared with the same period in 2025. No rolling year, no isolated quarter, no exceptions. One frame, held to the end.
The 10 numbers to pull: 60 minutes
1. Revenue attributable to digital
Where to find it: your accounts, cross-checked against the stated origin of each new client. Count generously, but honestly. A fictional example, used as a common thread: a Geneva-based service SME with CHF 410,000 in total revenue, of which CHF 96,000 came from inbound online enquiries, or 23%.
2. Marketing budget actually spent
Where to find it: your invoices. Add up advertising, tool subscriptions, external services and, above all, the line everyone forgets: internal time. A team member spending 20% of their time on social media, paid CHF 6,500 gross, represents roughly CHF 15,600 over the year. Without that line, your profitability figure is wrong.
3. Overall return on investment
Formula: (digital revenue − marketing budget) ÷ marketing budget. With CHF 96,000 generated for CHF 34,000 invested, you get 1.8 — meaning CHF 2.80 of revenue for every CHF 1 spent. Below 1, it isn't a failure: it's a signal that one specific line item costs too much.
4. Number of inbound enquiries
Where to find it: GA4, in your conversion events (form submissions, phone-number clicks, WhatsApp clicks), completed with your inbox. Count real enquiries, not technical triggers. In our fictional example: 214 enquiries in 2026 against 158 in 2025.
5. Cost per enquiry
Budget divided by number of enquiries: 34,000 ÷ 214 = CHF 159. This is the single most useful number in the review, because it compares directly from one channel to another and from one year to the next, with no room for argument.
6. Enquiry-to-client conversion rate
Where to find it: your CRM or, failing that, a manual count of your quotes. 214 enquiries for 47 signed clients is 22%. If that rate falls while volume rises, your problem isn't marketing: it's qualification or response time.
7. Organic traffic and its trend
Where to find it: Google Search Console, Performance tab, 12-month period. Look at clicks, never impressions. Going from 9,200 to 14,700 annual clicks means your organic search visibility in Geneva is working for you even in the months when you spend nothing on advertising.
8. The five pages that generate the most
Where to find it: GA4, "Pages and screens" report, cross-referenced with your conversions. Very often, a handful of pages produces most of your enquiries. By the end of this exercise, you will finally know them by name.
9. Performance of each paid channel
Where to find it: Google Ads, Meta, LinkedIn. Three columns are enough: spend, enquiries, cost per enquiry. A channel at CHF 88 per enquiry and another at CHF 340 do not deserve the same call next year.
10. Social media audience and engagement
Where to find it: the native statistics on each platform. Two numbers only: followers gained over the year and average engagement rate. The rest is noise and will cost your review thirty minutes.

Reading the numbers: three cross-checks that decide everything
A number on its own decides nothing. Three cross-checks bring out the real conclusions, and they take fifteen minutes.
- Cost per enquiry × conversion rate. An expensive channel converting at 40% beats a cheap one converting at 4%. Work out the cost per signed client, not just the cost per enquiry: CHF 340 per enquiry at a 40% close rate means CHF 850 per client, against CHF 2,200 for the "cheap" channel.
- Organic traffic × top-performing pages. If your five best pages are all more than two years old, your recent content hasn't found its audience. The problem lies in the topics chosen, not in the publishing rhythm.
- Budget × contribution to revenue. Line the two up as percentages. If social media absorbs 45% of the budget for 8% of enquiries, the imbalance is there in black and white, beyond debate.
Produce three decisions, not ten: 30 minutes
This is the step most companies skip, and it's the only one that produces an effect. A review without decisions is just an archive. Deliberately limit yourself to three calls, one per category.
- One stop decision. Which channel, tool or format are you cutting in 2027? The candidate is always the one whose cost per client exceeds your average gross margin. Cutting a CHF 8,400-per-year line frees up budget immediately.
- One reinforcement decision. Where do the recovered francs go? Into the channel with the best cost per client, provided it isn't already saturated. An SME seeing CHF 88 per enquiry on paid search is better off strengthening its Google Ads campaigns in Geneva than opening a fifth social network.
- One structural decision. Which recurring problem do you fix at the root? Response time to enquiries, forgotten quote follow-ups, reporting rebuilt by hand every month: this friction costs more than any channel, and it can be solved once and for all through AI-driven business automation.
Write each decision with a target number and a date. "Bring cost per enquiry down from CHF 159 to CHF 120 by 30 June 2027" is a decision. "Improve marketing" is not.
The deliverable: one page, not thirty
At the end of the two hours, you should be holding a single-page document: the table of ten metrics with the 2025-2026 comparison, the three cross-checks each summarised in one sentence, and the three dated decisions. That document can be re-read in five minutes in April, when the memory of the exercise has faded.
Share it with the whole team, including people who don't do marketing. The colleagues who answer the phone understand better than anyone why the conversion rate moved.
The mistake to avoid: confusing review with judgement
A review is not an assessment of your teams or a trial of your suppliers. The moment it becomes either, numbers start being presented rather than observed, and the exercise loses all value. Phrase everything in the first person plural, and keep the discussion on the decisions ahead rather than on past responsibility.
Second safeguard: never change your calculation method from one year to the next. A cost per enquiry calculated without internal time in 2026, then with it in 2027, will produce an artificial 40% jump and a bad decision. Consistency beats absolute precision.
What if the data is missing?
That's the most common situation, and it's no reason to give up. Run the review with what you have, explicitly list the numbers you couldn't produce, and make putting them in place your structural decision. An SME closing 2026 without knowing where its clients come from has an obvious priority for 2027: install conversion tracking and add a "how did you hear about us?" question to every form. The next review will then genuinely take two hours.
Block the date now, in your calendar, somewhere between 15 December and 15 January. Two hours, phone shut, one spreadsheet open. It's the best hourly return of your entire marketing year.
