Most home-service businesses get most of their work by phone. That is the reason call tracking exists, and it is also the reason it is so easy to get wrong. A form fill arrives with a page URL and a campaign tag attached. A phone call arrives with a number and nothing else. Unless you arrange otherwise, every call looks like every other call.
Call tracking arranges otherwise. The idea is simple: give each marketing channel its own phone number, forward every number to your main line, and record which one rang. The practice has a few traps, and the worst of them is not technical. It is the report that tells you what you hoped to hear.
How the numbers get assigned
There are two broad ways to hand out tracking numbers.
Static numbers are one number per source that never changes. The truck wrap gets one, the mailer another, the radio spot a third. They are simple and they work well for offline channels, where the number is printed or read out and there is nothing else to go on.
Dynamic number insertion (DNI) is for your website. A small script on the site looks at how each visitor arrived (a Google ad, organic search, a Facebook link, a direct visit) and swaps the phone number shown on the page for a number assigned to that source, sometimes to that individual visit. When they call, the tracking system knows where they came from, and often which page they were reading.
Both route to your real phone. The caller does not notice. What changes is that the call log now has a column that says where the call came from, which is the one column the phone system never had.
Keeping your listings consistent
Here is where owners get nervous, and they are right to think it through. Local search leans on your business name, address and phone number (NAP) matching across the web: your Google Business Profile, your website, directories, review sites. Scatter tracking numbers across those listings and you risk muddying the thing that helps you show up on the map.
A few rules keep tracking and consistency from fighting each other:
- Your main number is your identity. It stays on every citation and directory listing, and in your website’s page source. Most DNI tools swap the number in the visitor’s browser and leave the main number in the source, but check yours: Google renders scripts too, so do not assume a crawler never sees a swapped number.
- Your Google Business Profile needs care. A widely used setup puts a tracking number in the profile’s primary phone field and the main number in the additional phone field, which keeps the connection between the two. Google’s current guidelines do not spell this out; they do say the number must be under the business’s direct control, so read them before changing anything. Do not swap numbers on the profile casually, and do not put a different tracking number there every quarter.
- Do not put tracking numbers on directories. A directory listing with a number that goes dead when you cancel the tracking account is worse than no listing at all.
- Own your numbers, or be able to port them. If the tracking provider holds the number and you leave, the calls from every printed mailer go with them.
The Google Business Profile checklist covers the rest of the profile, including the phone fields.
First-time callers and repeat callers
This is the part where tracking tells flattering stories.
A customer who found you through a search ad three years ago, had a water heater installed, and now calls about a leak, will often find you again by searching your name, clicking the first result (which may be your own ad) and calling the number on the page. The tracking system dutifully records a call from the Google Ads campaign. The campaign did not produce that customer. It stood between them and your phone number and charged a click for the privilege.
Multiply that by every returning customer and a paid campaign can look far better than it is. The fix is to split every call report two ways:
| First-time caller | Repeat caller | |
|---|---|---|
| What it tells you | Which channel is finding new customers | Which channel existing customers pass through |
| How to tell | Number not in your customer list | Number matches an existing customer or past call |
| What to judge a channel on | This column | Mostly ignore for channel decisions |
Most call tracking tools flag first-time versus repeat callers on their own, based on whether the number has called before. Better still is matching the caller’s number against your customer list from your field software, because a customer who last called from a different line still shows as new to the tracking tool. Neither is perfect. Both beat a single number that mixes the two.
The same problem affects branded searches. People searching your company name already know you. If your paid campaign bids on your name, report those calls separately from calls on “ac repair near me”. Branded campaigns can be worth running, to hold the top spot against competitors bidding on your name, but they should not be allowed to prop up the generic ones in the same report.
The report worth reading
Once numbers are assigned and callers split, a useful monthly call report has few columns:
- Source, from the tracking number.
- First-time or repeat.
- Answered, missed or voicemail, from the phone system.
- Booked or not, joined from the field software by phone number and date.
- Ticket value, where the job is done.
That is enough to say which channel found new customers who booked, which is what the ad money is for. It also shows the uncomfortable column, the missed calls, next to the channel that paid for them. We made the case for that join in your ad spend is not the problem.
Common ways to fool yourself
A short list of common mistakes:
- Counting calls, not callers. One anxious customer who calls four times in an hour is one lead.
- Counting connected calls as answered. A call that reached voicemail connected. It was not answered.
- Forgetting spam and sales calls. Tracking numbers attract robocalls like any other number. Filter calls under a few seconds and known spam before counting.
- Leaving old numbers running. A mailer from two years ago keeps producing a trickle of calls on its number. That is good, but it is not this month’s mailer.
- Crediting the last touch with everything. A homeowner who saw the truck, read reviews and then clicked an ad was not won by the ad alone. Tracking shows the last touch. Keep that in mind when you are tempted to cut the channels it cannot see.
None of this needs to be perfect to be useful. It needs to be consistent, so that this month and last month are measured the same way. If you are working on local search at the same time, keep the listings rules above in front of whoever manages your SEO, so tracking and consistency are decided together rather than by two people who never talk.
