Call tracking tells you which ad, web page or listing made your phone ring. It works by showing a different phone number for each source, which forwards to your normal line and logs the call. Google already counts calls from your ads and taps on your Business Profile's call button for free. A paid call tracking tool adds the calls Google cannot see, plus recordings, and the two UK providers we checked in November 2026 listed plans starting at eighty pounds a month.
For a plumber, an accountant or a fire alarm engineer, the phone is often where the work comes in, and without call tracking every call arrives with no label on it.
How does call tracking work?
Each source gets its own number, and every number rings through to your normal phone. When a call comes in, the system notes which number was dialled, so it knows whether the caller saw your ad, your leaflet or your website.
There are two ways to hand out the numbers.
Static numbers
A static number is fixed to one place: one on the van, one in a directory listing, one on a leaflet drop. Anyone who rings that number found you there. Static numbers are simple and cheap, and they suit anything printed or listed that you cannot change per person.
Number swapping on your website
Number swapping (vendors call it dynamic number insertion) shows each website visitor their own number from a pool, and remembers how that visitor arrived: an ad, a Google search, Facebook, a link from another site. When they ring, the call is matched to that visit. The pool needs enough numbers for the people on your site at the same time, or calls get matched to the wrong visit.
What it looks like for a small firm
Say Mark runs an electrical firm in Northampton. He runs Google Ads, has a Google Business Profile, a website, his number on two vans, and a directory listing. His phone rings about 60 times a month, and he has no idea which of those five things to spend more on.
Google Ads can tell him which calls came from his ads. His Business Profile can tell him how many people tapped the call button. Everything else (the vans, the directory, people who found his website on their own) stays invisible until he gives each one its own number.
What can you track for free with Google?
Google gives you three call counts without paying for a tool. If your only paid marketing is Google Ads, these may be all you need.
| Option | What it counts | Cost | Recordings in the UK |
|---|---|---|---|
| Google Ads call reporting | Calls from the call button on your ads | No charge beyond the click | No |
| Google Ads website call conversions | Calls from your website by people who clicked an ad | No charge beyond the click | No |
| Business Profile performance | Taps on the call button on your profile | Free | No |
| Static tracked numbers | Calls from one fixed source (van, leaflet, directory) | Monthly fee plus call minutes | Yes, on most plans |
| Number swapping on your website | Website calls from every source, ad or not | Monthly fee plus call minutes | Yes, on most plans |
Google's help page on call reporting, checked on 12 November 2026, says it "uses Google forwarding numbers to measure the performance of your call asset or call ad", lists the United Kingdom among the countries where it works, and records "call duration, call start time, caller phone number for calls over 15 seconds". A call from the ad's call button is charged as a click.
For website calls, Google's page on phone call conversion tracking says a forwarding number will "dynamically replace your website number for users who clicked an ad". People who arrived any other way still see your normal number, so this only covers ad visitors. How to set both up, and how to count them properly, is in our guide to Google Ads conversion tracking.
Your Business Profile's performance page counts Calls as "the number of times a customer clicked on the call button on your Business Profile", according to Google's help page checked the same day. Those are taps rather than answered calls, but they make a free trend line.
What Google does not give UK businesses is call recording. Its help page on AI-qualified call leads says recording is "only available when both the dialling and receiving phone numbers are located in the United States or Canada". To hear calls back, you need a call tracking tool or a phone system that records. (Local Services Ads work differently again, charging per enquiry: see our guide to Local Services Ads in the UK.)
Should you put a tracking number on your Google Business Profile?
For a small firm, no: leave the main number on your Google Business Profile as it is. Track profile calls with the free performance count instead, and put tracked numbers on the things you control.
Some specialists do swap the profile's main number for a tracked one and keep the real number as an additional number. It can work. For a small business, though, the risk is bigger than the reward:
- Every edit is reviewed. Google's page on editing your Business Profile, checked on 12 November 2026, says "We review your changes" before they go live. Changing a key detail puts the profile back in front of Google's checks, and a number that matches nothing else about your business gives those checks less to go on.
- The number has to be yours. Google's guidelines say to "provide a phone number that connects to your individual business location" and that "the phone number must be under the direct control of the business". A tracked number belongs to the tracking company; if you stop paying, the number on your profile stops working.
- Your number is everywhere else. It is on your vans, invoices, reviews and directory listings. When the profile shows a different number, customers and Google both see a mismatch.
The profile allows extra numbers: the same edit page says you can add up to two more besides your primary number. You can also tag the website link on your profile with a UTM builder so visits from the profile show up under their own name in your analytics, and the website's number swapping will then credit those calls to the profile.
What do call recording and whisper messages do?
Recording keeps a copy of the call so you can check what was asked, how it was handled and whether it became a job. A whisper message is a short announcement that only you hear when you pick up, such as "call from Google Ads", before the caller is put through.
Recordings settle "who said what" about a quote and show whether calls are being rushed. A whisper lets whoever answers know which advert the caller saw. Of the two UK vendors we checked, Mediahawk lists call recording and call whisper on both of its published plans, and Clear Ring's pricing page says it keeps recordings for at least two years on every plan.
Do you have to tell callers you are recording?
Yes. If you record calls, you must tell callers that you are recording and why, and a short message at the start of the call is the simplest way to do it.
The ICO's guidance on monitoring calls, checked on 12 November 2026, says: "You must tell these people that you are recording the call and why", and "A recorded message is good practice." The rest of your privacy information, such as how long you keep recordings, can be given another way, for example by email or in your privacy notice. The ICO notes that this guidance is under review following the Data (Use and Access) Act, so check it again before you set up recording.
The ICO's page on the right to be informed adds the timing: people should get privacy information "at the time you collect their personal data from them". For a recorded call, that means before the conversation starts. A line such as "Calls are recorded for quality and training; our privacy notice is on our website" is the usual form. Take advice if callers share sensitive details, such as health or financial information.
How much does call tracking cost in the UK?
Expect a monthly plan plus a charge for each minute of calls, and more for freephone numbers. On 12 November 2026, the two UK vendors' pricing pages we checked started at eighty pounds a month and ran to a few hundred.
What the vendors' own pricing pages showed that day (neither page says whether VAT is included):
- Clear Ring lists a pay-as-you-go plan at eighty pounds a month with no minutes included and calls at eight pence a minute, and its next plan up at a hundred and twenty pounds a month with 500 minutes and five numbers. Its larger plans are two hundred and twenty and three hundred and ten pounds a month. Monthly plans roll month to month.
- Mediahawk lists its cheapest published plan at a hundred and ninety-nine pounds a month on monthly billing, or a hundred and seventy-nine pounds a month on an annual plan, with either one number pool for your website or ten fixed numbers. Calls are charged per minute on top.
The price moves with how many numbers you need, how many minutes of calls you take, freephone numbers, how long you keep recordings, and extras such as transcripts. Check the vendor's page on the day you buy.
Is call tracking worth it for a small business?
It is worth it once you spend money on more than one source and cannot tell which one makes the phone ring. If Google Ads is your only paid source, start with Google's free counts and see if they answer your questions.
Do the sum for Mark. A plan at a hundred and twenty pounds a month costs one thousand four hundred and forty pounds a year. If an average job leaves him three hundred pounds after materials and labour, the tool pays for itself if it helps him win or save the cost of five jobs a year (one thousand four hundred and forty divided by three hundred is 4.8). Moving budget away from a directory that never rings, or spotting that half his ad calls come in after six when nobody answers, could do that.
It is not worth it if nobody looks at the numbers each month and moves money as a result. For the wider question of where calls fit in a Google Ads plan, see our guide to Google Ads for small businesses.
Common questions
How does call tracking work with Google Ads?
Google Ads can track calls by itself through Google forwarding numbers, both from the call button on your ads and from your website for people who clicked an ad. Google Ads also accepts call conversions uploaded from elsewhere, which is how many call tracking tools pass their calls back when you want recordings or every source covered.
Can I keep my own phone number?
Yes. Tracked numbers forward to your existing line, so your own number stays on your profile, invoices and vans. Some providers also let you move an existing number to them, but you do not need to: the tracked numbers sit alongside yours and ring the same phone.
Do customers know they are ringing a tracking number?
Usually not. A local tracked number looks like any other local number, and the call rings your normal phone. The caller only hears something different if you add a recording message, which you need to do if you record calls at all.
Is call tracking legal in the UK?
Yes, and it is widely used. A caller's number and a recording can both be personal data, so mention call tracking in your privacy notice. If you record calls, the ICO's guidance says you must tell callers you are recording and why, and give the rest of your privacy information another way, such as your privacy notice.
What to do this week
Open your Business Profile's performance page and your Google Ads conversions, and note how many calls each one counted last month. Compare that with how many calls you actually took. If there is a big gap and you spend money on other sources, price a small plan with a handful of fixed numbers, put one on each source you pay for, and leave your main number on Google exactly where it is.
