Why guessing goes wrong
Two biases distort the picture reliably. Memorable enquiries feel frequent — one customer who mentions a leaflet outweighs twenty who silently found you on Google. And the most recent invoice paid feels causal, so whatever was purchased last tends to get the credit.
Meanwhile the map pack, which for many local businesses produces the majority of calls, leaves almost no trace. Someone searches, sees the top three, taps the number and rings. There is no website visit to record, no form submission, no obvious footprint — so the channel doing most of the work is often the one owners under-credit most.
Start by asking — properly
The lowest-tech method remains among the most effective, provided the question is asked well. "How did you hear about us?" invites a vague answer. "Did you find us on Google, or were you recommended?" gives people two concrete options and produces far more usable data.
The discipline is asking every time and writing it down somewhere consistent — a column in a spreadsheet, a field in your job software, anything that survives the week. A month of honestly recorded answers usually reshapes the owner's assumptions considerably.
Tag what happens on the website
For enquiries that arrive digitally, the site can label them for you. The practical minimum:
- A hidden field on each form recording which page the enquiry came from
- Analytics configured to treat form submissions and click-to-call taps as goals, not just page views
- Distinct tracking for the Google Business Profile's website link, so profile-driven visits are separable
- Consistent labelling of any paid or directory links so they cannot be confused with organic traffic
Use the profile's own numbers
The Google Business Profile reports its own activity: how many people called directly from the listing, requested directions, or clicked through to your website, and which searches surfaced you. This is the closest thing to a direct measure of map pack performance, and it is free and already sitting there.
It is not perfect — the categories are broad and the search data is partial — but combined with what callers tell you, it gives a solid picture of how much of your business originates in the map pack rather than anywhere else.
Review monthly, and act on it
Once a month, put the sources side by side against the work won. Not visits — won jobs, and ideally their value, because a channel producing a handful of large jobs may quietly outperform one producing many small ones.
Then let the pattern change the spending. This is the entire point, and it is where most tracking efforts fail: data collected and never acted upon is simply a slower form of guessing.
What good tracking makes possible
Once sources are visible, several decisions stop being arguments. Whether a directory subscription is earning its cost becomes a calculation. Whether SEO is working becomes measurable in enquiries rather than positions. Whether a quiet month was a market problem or a visibility problem becomes answerable.
Azizi Technologies sets this up at the start of a campaign rather than the end, because a campaign that cannot prove which work produced the calls cannot be improved deliberately — only continued hopefully.
