How to track phone calls from Google Ads

by Harry Watts · Last reviewed 18 October 2026

Count the calls, not the taps. Turn on call reporting so Google forwarding numbers show on your ads, add Google's website call snippet so they show on your site to people who clicked one, then count a call as a conversion only when it lasts long enough to be a real enquiry. A paid call tracking tool adds what Google's own tracking doesn't: recordings, which calls became customers, and calls from outside your ads.

If most of your enquiries are phone calls and Google Ads reports two conversions a month, the account isn't telling you how it's doing. It is telling you how many people filled in the form.

Why the calls have to be counted

I've taken over accounts with no call tracking in place countless times. That includes medium and larger businesses spending five or six figures a month on paid search. Even if phone calls aren't your main source of enquiries, if your number is on your website, people call it. Even at a small share of your leads, that's valuable conversion data you're missing out on.

Missing calls costs more than a report that looks thin. Smart Bidding needs conversion tracking to work at all (Google's Smart Bidding page), and it bids towards whatever is counted as a primary conversion. If only forms are counted, it learns to find people who fill in forms and never learns from the ones who ring. The same goes for Performance Max, which is only as good as the conversions it is given.

To an owner who tells me they don't need tracking because they know when the phone rings, I'd say this: "The more conversions you can get into your account, the more we can teach Google's bidding algorithm, and the more we can optimise the campaigns. In time, that gives you more leads, cheaper leads and better-quality leads."

Counting the wrong thing is the other half. A tap on a phone number is not a call, and treating taps as leads is one of the conversion tracking mistakes that makes an account look better than it is.

Five ways Google Ads can count a call

Google lists five kinds of phone call conversion (about phone call conversion tracking). They count different things, and only some of them count a call that actually happened:

For most businesses whose phone is the lead, the first two together are the core: they count calls that connected and lasted, from the ad and from the website. The third is the one to be wary of, and the fifth is where a paid tool usually comes in.

Setting it up

The order matters, because the conversion actions depend on call reporting being on first.

• Turn on call reporting. In Account settings, under Call reporting (about call reporting). It puts a Google forwarding number on your call assets and records each call's length, start time and whether it connected. The UK is on Google's list of forwarding number countries, with a freephone number equivalent to a local one (Google forwarding numbers). A forwarding number keeps connecting to you for 60 days after someone's last call to it.
• Create a conversion action for calls from ads. Goals, then Conversions, then a new phone call conversion (measure calls from ads).
• Add one for calls to your website number. This needs the Google tag on every page and Google's website call snippet on the pages that show your number, or the equivalent tag in Tag Manager (calls to a phone number on your website). The number in the snippet has to match the number on the page exactly, and the default tag tracks one number per page.
• Set the minimum call length. Google's 2018 announcement gave the default as 60 seconds (Google's announcement), and its current set-up pages don't state one, so check what the screen shows you. Set it to the shortest call that is usually a real enquiry for your business. Too short, and wrong numbers and cold calls count. Too long, and quick bookings don't.
• Count one conversion per click. That's Google's default for both call types, and the right one for leads: one person ringing twice about the same job is still one enquiry (counting options).
• Demote the taps. If the account already counts clicks on your number, keep that action as secondary. Google says secondary actions are for observation only: they're reported in All conversions but not used for bidding, unless you've added them to a custom goal (primary and secondary actions). Its default is to count every click.
• Test it. Click your own ad, ring the number you see on the site, and stay on the line past the minimum, then check the call reaches the conversion action. Google says a new website call action can take up to an hour to switch on.

If a test call doesn't show up, Google's set-up pages point to four causes: call reporting is off, the call was shorter than your minimum, the number in the snippet doesn't match the number on the page exactly, or the number is the second one on a page that tracks one. The swap also relies on a Google Ads cookie, which Consent Mode withholds when a visitor refuses advertising storage, so accept your own cookie banner before you test.

Measurement tested before the first click is one of the four things to have in place before you start Google Ads. For a local trade, Local Services Ads or Search covers the rest of the settings that waste a local budget.

Google's own tracking or a paid tool

Google's own tracking counts calls. It doesn't tell you what was said, whether the caller became a customer, or anything about the calls that didn't come from an ad. Those are the gaps a paid call tracking tool fills:

• Recordings. Google says its call recording is limited to calls where both parties are in the US or Canada (measure calls from ads), so in the UK, listening back to calls needs a separate tool.
• Which calls became customers. Google lets you import calls your own system has tracked to a sale or other outcome, with a value (import phone call conversions), and tools such as CallRail send call data to Google Ads for you. Bidding then learns from the calls that made money rather than the ones that passed your minimum call length.
• Calls from everywhere else. Google's forwarding numbers only cover visitors from your ads, and Google says not to promote them outside Google Ads. A tool tracks calls from the other ways people find you as well.

Some smaller clients can't pass a value back for each conversion, because of technical limits on their side. For them, call recordings are the feedback I'd otherwise not have. I can hear what the calls from different keywords and campaigns are actually like, and optimise on that.

I use CallRail for clients. I have no affiliate or referral relationship with CallRail, and the software is an additional cost on top of my fee. On 17 October 2026, CallRail's US pricing page listed its entry plan, Lead Tracking, at 50 a month plus usage, with call analysis on its Lead Conversion plans. No currency is shown, the page's add-ons are priced in US dollars, and the page offers up to 10% off for yearly billing without saying which rate the 50 is, so check before you budget (CallRail pricing). CallRail says it is available in the UK. Before you buy any tool, check what kind of UK number it will give you, because a caller sees the difference between a local number and a non-geographic one.

Consent and the number swap

The number on your website changes because a script swaps it, and Google's own testing instructions name the cookie it uses to remember the ad click (calls to a phone number on your website). Paid tools swap the number with a script too, which CallRail calls dynamic number insertion.

The ICO lists ad measurement and performance among the advertising purposes that need consent, and says the new statistics exception never covers advertising (the ICO's exceptions). It doesn't mention call tracking. But measuring what the ads produced counts as advertising, so a swap that reports calls back to Google Ads needs consent like any other advertising tag. Consent Mode stops Google's tags storing cookies for a visitor who refuses, so expect fewer website calls to be attributed than calls received.

How the banner and Google's consent signals fit together is in Consent Mode v2 for UK advertisers.
