Your phone rings. Someone wants a water heater replaced. You book the job, you hang up, and you have no idea whether that call came from your Google Ads spend, your Google Business Profile, a sign on a truck, or a neighbor's referral. Multiply that by forty calls a month and you're running a campaign you cannot evaluate.

The fix isn't a single tool. It's a chain: the click has to be connected to the ring, and the ring has to be connected to whether you actually got work out of it. Google handles the first part reasonably well if you configure it. The second part is on you.

The five ways a call can reach you

Google Ads documents five distinct phone conversion types, and they are not interchangeable. Knowing which ones apply to you is most of the battle.

Calls from ads. Someone taps the call asset attached to your ad and dials without ever seeing your website. Tracked through a Google forwarding number.

Calls to a number on your website. Someone clicks your ad, lands on your site, then picks up the phone and dials the number on the page. Google dynamically swaps your displayed number for a forwarding number for that visitor, so the call is tied back to the click.

Clicks on a number on your mobile site. Someone taps a tel: link. Google is explicit here: it can track the click, not the call. You don't know if it connected, how long it lasted, or whether it was a misdial.

Clicks on call ads and assets without a forwarding number. A click counts as a conversion based on Google's estimate that a meaningful call happened. Weaker signal, no call detail.

Imported call conversions. You track calls in your own system — a CRM, a scheduling tool, a third-party call platform — and upload the ones that actually mattered. This is the only method where you decide what counts.

Most local service accounts need the first two running, and eventually the fifth.

Call reporting is the switch everything hangs off

Google forwarding numbers only work when call reporting is turned on at the account level (Admin → Account settings → Call reporting). Turn it on and Google assigns a tracking number that routes through to your real line, capturing duration, time, and which campaign and keyword produced the call.

Turn it off and your own number shows on the ad. You get clicks. You get nothing else.

Two practical warnings. First, the forwarding number is not yours — Google says it can change over time, and it isn't meant to be copied onto business cards, your Business Profile, or anywhere outside your ads. Second, if a forwarding number ever routes badly (voicemail errors, calls not connecting), Google's own troubleshooting advice is to switch call reporting off temporarily to confirm that's the cause.

What changed in 2026, and why it matters more than the setup steps

For years a call counted as a conversion if it lasted longer than a minimum length you set. That was always a crude proxy. A robocall can run three minutes. A homeowner who books an appointment in forty seconds gets thrown away.

In April 2026 Google published documentation on AI-qualified call leads, which reorders the signals. Call recording is now the primary signal: if recording is on, Google's AI evaluates the conversation for intent — someone asking about a specific service, scheduling a consultation, showing readiness to buy — and only qualified calls count. Call duration becomes the fallback when a call can't be recorded. Ad interaction data is the last resort if no forwarding number was available.

The part that catches owners off guard: call recording is now on by default. Google's help documentation states recording was enabled by default to support AI lead qualification, with exceptions for advertisers who had previously turned it off and for businesses identified as healthcare or financial services. You can turn it off any time under Admin → Account settings → Call ads → Call recording. If you do, measurement falls back to duration.

The constraints are worth knowing:

  • Recording and AI qualification are currently limited to calls where both numbers are in the United States or Canada.
  • Calls must flow through a Google forwarding number, which means call reporting must be on.
  • Only calls to call ads, call assets, or calls from website visits are eligible. Calls from location assets are not supported for recording.
  • Callers hear a short automated message telling them the call is being recorded, and by using the feature you're confirming you've notified your own staff.

If you're a dentist or a personal injury firm, that last point is not a footnote. Recording consent law varies by state and by industry, and your intake calls may carry obligations Google's automated disclosure doesn't satisfy. Decide deliberately rather than by default, and if you're unsure, ask your attorney before leaving it on.

Call-only ads are going away

If your account leans on call-only ads, that lane is closing. Google announced the deprecation in October 2025: creation of new call-only ads ended in February 2026, and existing call-only ads stop receiving impressions in February 2027. The replacement is responsive search ads with call assets.

Practically, that means every ad group that used to be call-first now needs a landing page and a call asset, and the phone number on that page needs to be tracked. If you were previously sending all mobile traffic straight to the dialer, your tracking work just got bigger — you now have a website step in the middle, and website call conversions require tags.

The build, in order

  1. Turn on call reporting in account settings. Nothing below works without it.
  2. Create a "Calls from ads" conversion action (Goals → Summary → Create conversion action → Conversions from phone calls → Phone call lead). Note that once call reporting is on, Google starts counting calls under a default "Calls from ads" action automatically and includes it in your Conversions column.
  3. Create a "Calls from website visits" action and install the Google tag plus the phone snippet on your site. The phone number you enter has to match the digits exactly as displayed on your page, or the dynamic number swap won't fire.
  4. Set your qualification rule. With recording on, AI decides. With recording off, set a minimum duration that reflects what a genuine inquiry sounds like in your business — a roofing estimate call and a dental appointment call are not the same length.
  5. Mark the right actions primary. Google warns that misconfiguring primary versus secondary breaks Smart Bidding, because the algorithm optimizes toward whatever you've told it is the goal. Don't make mobile number-clicks primary alongside real call conversions — you'll be bidding toward the same lead counted twice.
  6. Verify. Use Tag Assistant for the website tag, and pull the Call details report (Report Editor → Ads and Assets → Call details) to see actual durations, times and call status.

That sequencing matters more than any individual setting, and it's the same discipline the rest of your account needs — the piece we covered in Conversion Tracking: The Setup Most Local Accounts Get Wrong applies here almost verbatim.

Reading the call report like an owner, not a marketer

Once data is flowing, the Call details report answers questions you've probably been guessing at:

  • Are calls coming in when nobody answers? Cluster them by hour. If a third of your ad-driven calls arrive after 6pm and roll to voicemail, the problem isn't your keywords, it's your ad schedule or your answering service.
  • How many are junk? A pile of eight-second calls usually points at bad search terms, not bad tracking. That's a negative keyword problem.
  • Which keywords produce long calls? Duration is imperfect, but keyword-level call data is the single most useful thing call tracking gives a service business. Emergency-intent terms and "near me" terms behave very differently from research terms.

The gap Google can't close for you

Google can tell you a call happened and, now, that it sounded like a real lead. It cannot tell you that the caller booked, that the job was worth $9,400, or that they cancelled. Your bidding is only as good as the definition of success you feed it.

That's what imported call conversions are for. You track outcomes in your CRM or scheduling software, then upload the calls that turned into sales — optionally with values attached — and Google matches them back to the original ad interaction. Google's documentation describes exactly this workflow. The third-party call platforms (CallRail, CallTrackingMetrics, WhatConverts and others) exist largely to automate that loop, and Google supports a "call details forwarding" integration that passes campaign, ad group and click IDs through to supported providers.

One caution if you go third-party: don't run both systems blindly. If you want your own tracking numbers shown on ads, Google's guidance is to turn call reporting off so your number appears instead of a forwarding number — or to use a provider that supports call details forwarding so the two layers cooperate rather than collide.

The order that actually produces a decision

Track the call. Qualify the call. Then connect the qualified call to revenue. Most local accounts stop at step one, end up with a "Conversions" number that includes wrong numbers and vendor calls, and then wonder why Smart Bidding chases the wrong traffic.

If you want the full build — campaign structure, tracking, call handling and the weekly review routine that turns all of it into decisions — that's what Launchpad walks you through step by step.

Start with call reporting today, though. Everything else is downstream of that one switch.
