For a plumbing business, many of the best leads arrive as a phone call, often from someone with a leaking pipe who does not want to fill in a form. If Google Ads only tracks form fills, a lot of your real results go unseen, and automated bidding has less to learn from. This guide explains Google’s call reporting and call conversion tracking, what each tracking type actually measures, and the checks I would make before trusting call numbers in a plumbing account.

How call reporting works
Per Google Ads Help, call reporting uses Google forwarding numbers to measure the performance of call assets, location assets and call ads. When it is on, Google shows a unique phone number with your ads. When someone calls that number, Google Ads routes the call to your real business number. You can then see reports on calls from your ads, including call duration and caller area code.
Google notes the number may look unfamiliar, but it is how calls from ads are tracked. To turn it on, open Account settings from the Admin menu, find Call reporting, choose On and save.
What to know before you switch it off
- If you turn call reporting off, Google Ads stops tracking “Calls from ads” as conversions, which can affect Smart bidding strategies that rely on that data.
- Changes can take up to 24 hours to show in live ads.
- Call reporting is available in several countries. If you cannot find the option in Account settings, your country or account type may not support Google forwarding numbers.
So if you prefer to show your direct number everywhere, you give up call tracking. For a service business that depends on calls, I would rarely recommend that.
The five ways Google tracks phone call conversions
Google’s page on phone call conversion tracking lists five methods. They do not measure the same thing, so it helps a plumber to know which one a report is using.
- Calls from ads. Calls made directly from call-only ads, or from call and location assets. You set a minimum call length, and every call at least that long counts as a conversion. Google says call reporting must be enabled and the “Calls from ads” conversion action should be active and set as a primary goal.
- Calls to a phone number on your website. Someone clicks your ad, then calls the forwarding number shown on your site. This needs the Google tag and a specific event snippet for website call conversions on the site.
- Clicks on a number on your mobile website. Google says here it can only track the clicks, not the calls themselves.
- Clicks on call ads and assets. A click counts as a conversion based on Google’s estimate of whether a meaningful call followed, with no forwarding number.
- Imported call conversions. You import conversions that you track in another system. Google says this gives more control, for example counting a call only when it ended in a sale and including the value of that sale.
The difference matters. A “click on a number” is not a call, and an estimated conversion is not a booked job. For a plumber, imported conversions are the most accurate option if you can record which calls became jobs, because you are no longer counting every call equally.
What the call report shows
Google’s page on analysing call reporting data says you can see impressions, phone calls received and the phone-through rate (PTR), which is phone calls divided by the number of times your number was shown. You can also see details for each call, such as start and end time, whether the call was missed or received, the caller’s area code and the call type.
Two limits from that page are worth remembering. Manually dialled calls are counted at campaign and ad group level but not for individual keywords or ads, so keyword-level call totals can be lower than the real number. And Google says you cannot use a Google forwarding number outside call reporting and website call conversion tracking, so do not print it on a van or a flyer.
My checks for a plumbing account
These are my own steps, in the order I would take them:
- Call it yourself. Click your own ad on a phone, make a call and confirm it appears in the account. Do not assume it works.
- Check who answers. The best tracking cannot fix a missed call. Make sure the real number reaches someone, including out of hours or to a voicemail that promises a call back.
- Set the minimum call length on purpose. A too-short setting counts wrong numbers and hang-ups as conversions. A too-long setting hides real short enquiries. Pick a figure that fits how your calls usually go, write it down and keep it stable so month-to-month reports mean the same thing.
- Look at missed calls. The call details show whether a call was missed. If many calls are missed at certain times, that is a staffing or phone-routing problem, not an ads problem.
- Compare with the job book. Ads reports show calls, not revenue. Ask the business which calls became jobs, then compare. If the gap is large, consider imported call conversions.
- Keep the website number consistent. If you use website call tracking, make sure the number on the page is the one that the tracking replaces, and test it on mobile and desktop.
Common mistakes
- Turning call reporting off to show a “cleaner” number, then wondering why call conversions disappear.
- Counting every click on a phone number as a lead.
- Judging the account by call volume alone, without checking which calls were real jobs.
- Letting calls ring out during the hours the ads are running. If nobody picks up at certain times, change the schedule or the phone routing.
A worked example
This is a made-up example to show the method, not a result. Say a plumbing account reports 40 calls in a month with a minimum call length of 30 seconds. The owner’s job book shows 12 of those became booked jobs. The remaining calls might be wrong numbers, price checks, suppliers or customers outside the service area. That gap is the useful finding. It suggests checking the ad text for what you do and do not do, adding negative keywords for non-customers, and possibly importing the booked jobs as conversions so bidding learns from real work instead of every call.
Questions to ask your phone team
- Which numbers do customers see on the ad, the website and the Google listing, and do they all reach someone?
- Who answers after hours, and what do they say?
- Is there a simple way to note where each caller found you, even a line in a notebook or job software?
- How quickly are missed calls returned?
The answers decide how much any tracking setup is worth. Good tracking on a phone that nobody answers still loses jobs.
What this does not promise
Tracking tells you what is happening. It does not guarantee more calls or lower costs, and I do not promise either. If you want me to review how calls are tracked in your account, see my plumber Google Ads page, or message me on WhatsApp at +91 7987119702 or by email at [email protected].
Frequently asked questions
Does a click on a website phone number prove a call happened?
No. A mobile phone-number click can be tracked without confirming the actual conversation. Keep click events separate from measured phone calls and booked plumbing jobs.
What minimum call length should a plumber use?
Choose it from the business’s real enquiries rather than copying a universal number. Too short can count hang-ups; too long can miss useful short calls. Document the choice and compare it with call records.
Why can reported calls differ from booked jobs?
Some calls are missed, irrelevant, outside the service area or only price enquiries. Compare call details with the job book so you can see which contacts became work.
What should I check before trusting a call conversion report?
Check the conversion action being measured, the call-length setting, phone routing and website tracking where used. Reconcile the report with received and missed calls rather than assuming every conversion means a sale.
