Google Ads Conversion Tracking for Calls and Forms

An electrician in the northeast tells us his Google Ads account says he got 40 conversions last month. He also says the phone barely rang. Both are true: the account was counting every visit to his contact page as a conversion, so Google was busy optimising for people who looked at a page, not people who called.

That's the problem Google Ads conversion tracking solves when it's set up properly, and creates when it isn't. For a local service business, a conversion is a call or a quote request, and those need to be tracked carefully. Here's how to do it for both, in plain English.

01Why conversion tracking matters more than anything else

Most Google Ads bid strategies now rely on automation. Google decides how much to bid in each auction based on how likely it thinks a click is to convert. It learns that from the conversions you track.

So tracking isn't just reporting. If you track the wrong thing, Google gets very good at delivering the wrong thing. If you track nothing, it has no idea what a good click looks like, and neither do you.

Google Ads optimises for whatever you tell it a conversion is. Tell it the truth.

02The three lead types to track

For a typical service business, leads come in three ways. Each one needs its own conversion action.

There's a fourth, softer option: tracking taps on the phone number on your mobile site. That records intent, not an actual call, so treat it as a secondary signal rather than the number you optimise toward.

03Setting up call conversions

Calls from your ads

Add a call asset (Google used to call these call extensions) with your business number. Turn on call reporting so Google can use a forwarding number, then create a conversion action for calls from ads. The key setting is the minimum call length: Google's default is 60 seconds, which is a sensible starting point for most trades. A 10-second call is usually a wrong number or a hang-up.

Calls from your website

This is the one most small accounts miss. Many people click the ad, look at your site and then call. To catch those, create a website call conversion. Google gives you a small snippet that works with the Google tag to replace the number on your site with a forwarding number for visitors who came from an ad, so the call can be tied back to the click. Everyone else still sees your normal number.

When to use a dedicated call tracking tool

Google's call tracking only covers ad-driven calls. If you want to know what your Google Business Profile, Facebook ads or truck wraps bring in, or you want recordings to check how calls are handled, a dedicated tool is worth a look. Our guide to call tracking for small businesses covers the options.

04Setting up form conversions

A form conversion should fire once, after a real submission. There are two reliable ways to do that.

1. Thank-you page. After the form submits, send people to a dedicated page (for example /thank-you). Set the conversion to fire when that page loads. Simple and dependable, as long as nobody can reach that page any other way.
2. Submission event. If your form shows a message without loading a new page, fire the conversion on the confirmed submission event, usually through Google Tag Manager or code your developer adds. Don't fire it on a button click, because a click with a missing field isn't a lead.

If the form itself is the problem, with too many fields or a confusing layout, see why ads get clicks but no calls.

05The settings that decide whether your numbers are honest

Each conversion action has a few settings that are easy to skip and important to get right.

• Count: one. For leads, count one conversion per ad click. Someone who calls twice and submits the form is still one lead.
• Primary vs secondary. Primary actions are used for bidding and appear in the main Conversions column. Make real calls and real form submissions primary. Make soft signals like phone number taps secondary.
• Value. If you know roughly what a lead is worth, give it a value. If calls are usually worth more than forms for you, reflect that. Illustrative example: say an average job is worth $1,500 and you book one in four leads, a lead is worth roughly $375.
• Conversion window. The default is 30 days. For a service business where people decide within a few days, the default is fine.
• No duplicates. If you import conversions from Google Analytics and also use Google Ads tags for the same thing, make one primary, or you'll count every lead twice.

06Enhanced conversions and offline imports

Basic tracking tells Google that a lead happened. It can't tell Google which leads turned into paying work. For a local business, those are very different things. A tire-kicker and a $15,000 roof replacement look identical to the tag.

Enhanced conversions

Enhanced conversions add hashed first-party details, such as the email or phone number entered in your form, to your conversion data. Hashing scrambles the details before they're sent, and Google uses them to match conversions to signed-in Google users. That helps recover conversions that cookies alone miss.

Enhanced conversions for leads and offline imports

This is where it gets useful. With enhanced conversions for leads, Google captures the hashed details when the form is submitted. Later, you upload a list of which leads became customers, from your CRM or even a spreadsheet, and Google matches them back to the original clicks. You can also import offline conversions using the click ID that Google adds to the landing page URL, if your form saves it.

Once Google knows which clicks became booked jobs, you can set that as a conversion goal and let bidding chase real customers instead of any form fill. If you're collecting lead data, keep it in a system you trust. Our post on choosing a CRM in Canada covers the options.

07How to test that it's actually working

1. Check the tag. Use Google's Tag Assistant to confirm the Google tag loads on every page, including the thank-you page.
2. Submit a test form. Fill in your own form the way a customer would and confirm the conversion fires once, not twice.
3. Check the status. In the conversions area of Google Ads, each action shows a status. After real traffic, it should show it's recording conversions. New data can take a few hours to appear.
4. Compare with reality. After two weeks, compare conversions in the account with the calls and forms you actually received. They won't match perfectly, but if Google says 40 and you got 6, something's wrong.

Broken tracking is one of the most common problems we see in small accounts, and it sits near the top of our list of Google Ads mistakes small businesses make.

08Where Sidekick fits

Call and lead tracking is built into our website and Google Ads package ($1,285 CAD), so calls and form submissions are tracked from the day ads go live, on a site we design for it. If you already have a site and ads, the steps above are very doable with a free afternoon and a test form. If you'd like someone to check what your account is counting, book a free call or see the package.

Frequently asked questions

Can Google Ads track phone calls?

Yes. Google Ads can track calls made directly from call assets on your ads, and calls to a Google forwarding number shown on your website after someone clicks an ad, where forwarding numbers are available. You set a minimum call length that counts as a conversion.

Why is Google Ads showing no conversions?

Common causes are a missing or broken Google tag, a conversion firing on the wrong page, a form that confirms without loading a new page, or conversion actions set to secondary. Use Google's Tag Assistant and a test submission to find which one it is.

Should I count every conversion or one per click?

For leads, count one per click. If someone submits your form twice or calls three times, it's still one potential customer. Counting every conversion makes sense for sales where each purchase has value.

What are enhanced conversions for leads?

A Google Ads feature that captures hashed details such as an email address when someone submits your form. Later you upload which leads became customers, and Google matches them back to the ad clicks without needing the click ID.

Do I need separate call tracking software?

Not always. Google's own call tracking covers ad-driven calls. A dedicated call tracking tool helps if you want recordings, tracking for every channel, or detail Google doesn't give you. See our call tracking guide.
