Call Tracking Setup for Google Ads: An Australian Guide

Call Tracking Setup for Google Ads: An Australian Guide

To set up call tracking for Google Ads, turn on call reporting, create the right call conversion actions, set a sensible minimum call length, and then match calls to closed sales in your CRM. The first three steps take an afternoon. The last one is what separates a number on a dashboard from a measure of revenue.

I’m Jesse, a senior paid media specialist at Senior Ad Managers. Most call tracking problems we see in Australian accounts are not technical. The tracking “works”, but it counts every ring as a lead, and the campaigns are trained to chase more of the same.

TL;DR

• Google forwarding numbers and dynamic number insertion (DNI) tie phone calls to the ad, campaign and keyword that produced them.
• Set a minimum call length that matches your sales cycle. Otherwise hang-ups and wrong numbers become conversions.
• Platform-reported calls measure volume, not value. Import offline conversions from your CRM so Google learns which calls turned into revenue.
• Tell callers at the start if you record, and check the rules before you call leads back.
• Fix tracking before you scale spend. Scaling on bad call data just buys more of the wrong calls faster.

What call tracking actually measures

A click is easy to track. A phone call is not, because the customer leaves the browser the moment they pick up the phone. Without call tracking, a plumber, dentist or law firm gets a Monday morning full of calls and no idea which keyword caused them.

Google describes five types of phone call conversions you can track. The three that matter for most Australian businesses are:

1. Calls from ads. Someone calls straight from a call asset or call-only ad.
2. Calls to a number on your website. Someone clicks an ad, lands on your site, then calls the number displayed there.
3. Clicks on a number on your mobile site. Someone taps your phone number on a mobile page, which is counted as a conversion action.

Each one needs its own conversion action, and each one counts differently. If you only set up the first, you will miss most of the calls that happen after a visit to your site.

Google forwarding numbers: the built-in option

A Google forwarding number is a unique number that Google provides so it can track calls generated by your ads. It is switched on through call reporting in your account settings. Google’s help page confirms forwarding numbers are available in Australia, and that they work by dynamically replacing your business number on your website for people who arrived from an ad.

That swap is the dynamic number insertion most people are searching for. A small piece of code on your site checks how the visitor arrived. If they clicked a Google ad, they see a Google number. Everyone else sees your normal number. When the call comes in, Google knows which campaign, ad group and keyword started it.

Setting it up, step by step

1. Turn on call reporting. In your Google Ads account, open the conversion settings for calls from ads and switch call reporting on. This is what allows Google to use forwarding numbers.
2. Create a conversion action for website calls. Go to Goals, then Conversions, then create a new conversion action and choose phone calls. Select the option for calls to a phone number on your website.
3. Add the Google tag and the call snippet. Google’s setup instructions for tracking calls to a website number cover the website code. If you use Google Tag Manager, add it there so you are not editing site files by hand.
4. Make sure your number is easy to swap. The number on your site should be in a consistent format and live text, not an image. If your number is baked into a logo or a banner graphic, it will not change.
5. Set the minimum call length. More on this below, because it is the setting that most affects data quality.
6. Test it. Click your own ad (from a device that is not signed into your account, and accept that it costs you a click), call the number you see, stay on for longer than your minimum, then check the conversion shows as recorded. Google can take a while to report, so check again the next day.

If the number on your site never changes during testing, the usual culprits are a tag that does not load on that page, a cached page, or a phone number hard-coded in a theme file the script cannot reach.

Set the call length before you do anything else

With calls from ads and calls to a website number, you choose a minimum call length, and every call lasting at least that long counts as a conversion. Google also notes that if calls are not being recorded, the call length setting may be too high for your business, and you can check real durations in the call details report.

This is where wasted spend hides. A 10-second hang-up, a wrong number or someone asking for directions is not a lead. If you count them, Smart Bidding treats them as wins and goes looking for more of them.

There is no universal right answer. As a starting point, a minimum of around 60 seconds suits many service businesses, but your own call data should decide:

• Emergency trades (blocked drains, electricians): a genuine job enquiry can be short, because the caller knows what they want. A lower threshold may suit you.
• Law firms and clinics: first calls tend to be longer, because the receptionist takes details. A higher threshold keeps out the brief admin calls.
• Multi-location businesses: look at call length by location. A branch with a busy front desk can have very different call patterns to a head office line.

Pull the call details report for a month, listen to or log a sample of calls at different lengths, and find the point where most calls become real enquiries. Set the threshold there.

Count each lead once

Call tracking creates a double counting trap. A person clicks your ad, fills in your form, then rings to check you got it. That is one lead, but your account may now show a form conversion and a call conversion.

Double counting inflates your lead numbers and flatters your cost per lead. It also confuses bidding. The fix is to decide what a lead is, and de-duplicate in your CRM by phone number or email. When you later import offline conversions, you send one record per real lead, not one per touch.

Separate brand calls from new demand

If your ads bid on your own business name, many of those calls come from people who already know you. They would have called anyway. Your tracking will happily report them as ad-driven.

On acquisition campaigns, add your brand terms as exclusions, and run brand in its own campaign so you can see it separately. Otherwise a campaign with a strong-looking cost per call may be mostly harvesting existing customers. The calls are real, but the ads did not create them.

Why platform call data is only half the story

The platform tells a good story, but it does not know who actually bought something. Google Ads documentation describes tracking calls to a website number as a way of understanding how effectively your ads lead to phone calls. It measures calls. It cannot tell you whether the caller became a paying customer.

So a Google forwarding number on its own gives you volume, not value. A plumber might see 80 calls from a campaign and think it is working, when 50 of them were quotes for jobs outside the service area and 10 were suppliers selling something.

Closing the gap with offline conversion import

The fix is to record the outcome of each call in your CRM, then send the sales that closed back to Google Ads as offline conversions. In practice:

1. The call is captured with its Google click identifier (gclid) or call details.
2. Someone in your team logs the call in the CRM as a lead, then updates the status as it moves to quote, won or lost.
3. When a deal closes, the conversion and its dollar value are uploaded to Google Ads.
4. Google sees which keywords and campaigns lead to revenue, not just ringing phones.

We cover the mechanics in our guide to offline conversion import from HubSpot to Google Ads. If the conversion tracking itself is shaky, start with our piece on Google Ads conversion tracking.

A worked example, with made-up numbers purely to show the arithmetic: say a campaign spends $6,000 in a month and records 60 calls over your minimum length, so $100 a call. In the CRM, 12 turn into booked jobs worth $900 each, so $10,800 in revenue. Now your real figure is $500 per job and a return of 1.8 times the spend. Both views come from the same campaign. Only one is useful for deciding whether to increase the budget.

Practical rules for a clean setup

Here is what we check in an account before we trust its call numbers.

• One primary call conversion per call type. Do not have three overlapping actions all marked primary, or the same call is counted several times.
• Phone numbers consistent across the site. The header, footer, contact page and landing pages should all be covered by the swap.
• Call assets and location assets enabled where relevant, with call reporting switched on so those calls are tracked too.
• Keywords on exact and phrase match. We do not recommend broad match. Broad match pulls in loosely related searches, and call-driven campaigns are especially exposed, because a phone call is easy to trigger and hard to qualify. Tight exact and phrase lists, with a solid negative keyword list and a regular search term review, keep call volume attached to real intent.
• Negative keywords from the calls themselves. When you listen to calls and hear “do you do X?” over and over for something you do not offer, add X as a negative.
• Ad schedule that matches who answers the phone. Paying for calls at 9pm that go to voicemail is a common leak. If you cannot answer, consider restricting call-focused ads to business hours.

Businesses in the trades and professional services often rely on this kind of setup. Our page on Google Ads for service businesses explains how we structure those accounts.

Do you need third-party call tracking software?

Google’s forwarding numbers are enough for many small accounts. They tie calls to Google Ads campaigns and keywords, and they cost nothing beyond the ad spend.

Dedicated call tracking platforms, which you buy from a phone or software provider, make sense when:

• You advertise across several channels, such as Google, Meta, Microsoft Ads and organic search, and want calls from all of them in one place.
• You want call recordings, transcripts or keyword-level reporting outside Google’s interface.
• You need to score call quality automatically, rather than listening to samples.
• Your CRM can receive call data directly, so each call lands as a lead with its source attached.

If you go that route, check that the platform can pass call details and the Google click identifier into your CRM, and that it uses Australian numbers, so callers see a local-looking number rather than something unfamiliar that they may not answer. Whatever you choose, the principle holds: tracking is only useful if it ends in a closed sale you can see.

If your business also advertises on Microsoft, the same logic applies there. We run Microsoft Ads for Australian businesses with the same CRM-first approach.

Recording calls: what Australian law expects

Recording calls is optional for tracking, but many businesses do it for training and quality checks. This is the part to take seriously, and I am not a lawyer, so for your own situation speak to one.

The Office of the Australian Information Commissioner says that it is not enough to simply tell people about collection, and that unless you offer an opt-out, you cannot assume implied consent. Its guidance for health providers also stresses that consent needs to be informed, voluntary, current and specific, especially with sensitive information. Australian Privacy Principle 5 requires reasonable steps to notify people when you collect their personal information.

In practical terms:

• Play or say a recording notice at the start of the call, before any personal details are discussed.
• Give the caller a real way to object, for example by continuing without recording or being transferred to someone who is not recording.
• Do not rely on a line buried in a privacy policy.
• If you are a clinic, dental practice or NDIS provider, the information on the call is likely to be health or sensitive information, so the bar is higher. Get advice before you record.
• State laws on listening devices also differ, so check the rules in each state where you operate.

If you want to understand why callers ring and what they expect from the conversation, market research and customer journey studies can complement call data with the human side.

Calling leads back

Call tracking often leads to outbound follow-up. If you call people back who enquired, that is different from cold telemarketing, but be careful if you buy lists or call numbers that did not contact you. Under the Do Not Call Register Act, a telemarketing call to a number on the Register is prohibited once it has been registered for at least 30 days, unless an exemption applies. The ACMA says businesses stay responsible even when a third-party data supplier provides the list. If outbound calling is part of your sales process, get the rules checked.

Our view: what we see in accounts

We have audited enough accounts to see the same pattern. The business has a Google forwarding number, a call conversion with a very short minimum length, and a campaign reporting a pleasing cost per call. Nobody has compared those calls with what the CRM says was sold.

We work in a fixed order. We fix tracking first, then cut the spend that is not producing real customers, then measure campaigns against closed revenue in the client’s CRM. Brand searches are split from new demand, each lead is counted once, and ROAS is reconciled to real sales. That order matters. If you scale spend on bad call data, you are paying to teach Google the wrong lesson.

Call tracking is a good example. It is cheap to turn on and easy to get wrong. The setting that matters most, minimum call length, takes a minute to change, yet it decides what Smart Bidding learns.

In the work we have shared publicly, a telehealth provider added 600+ new patients in 12 months through Google and Meta Ads, and a DTC supplement brand grew from $15k to $90k a month in revenue on Meta Ads. Those results came from measuring against real outcomes, not platform-reported numbers. No agency can guarantee results, and we do not. What we can do is make sure you are measuring the right thing.

Where to start if your tracking is unreliable

If you are not sure your calls are counted properly, begin with a review rather than a rebuild. Check which conversion actions are primary, what the minimum call length is, whether the number swaps on every page, and whether any of it connects to your CRM.

Our $99 AUD Google Ads audit covers exactly this: tracking, wasted spend and how your account maps to real sales. If you want us to fix and maintain it, see our website tracking service or Google Ads management. There are no 12-month lock-ins, and we will tell you upfront if we cannot help.

FAQ

How does dynamic number insertion work?

A small script on your website checks where each visitor came from. Visitors from a Google ad see a tracking number, and everyone else sees your regular number. When the tracking number is called, the call is matched to the ad, campaign and keyword behind that visit.

Can I track Google Ads calls for free in Australia?

Yes, for Google Ads calls. Google forwarding numbers are available in Australia and are switched on via call reporting. They only cover Google Ads, so calls from other channels need a separate method.

What minimum call length should I set?

It depends on your business, so check your own call data. Many service businesses start around 60 seconds, then adjust after reviewing real calls. Emergency trades may go shorter, and clinics and law firms may go longer.

Do I have to tell callers I am recording?

Yes. Tell people at the start of the call, before personal details are discussed, and give them a genuine chance to object. The OAIC says consent cannot be assumed from a notice alone. For legal advice on your situation, speak to a lawyer.

How do I know which calls became sales?

Log every call as a lead in your CRM and update its status as it progresses. Then import the closed deals into Google Ads as offline conversions, so reporting reflects revenue and not just ringing phones.
