How to set up Google Ads in the US: track calls before you spend

Short answer: A US small business should set up Google Ads in the order tracking, targeting, campaign, budget, not the order Google’s set-up screens suggest. Create conversion actions for calls and form fills first, target the ZIP codes you actually serve, and start with one Search campaign you can read. Judge it on the last 30 days with at least 30 conversions, which is Google’s own guidance for Target CPA.

If you run a plumbing, roofing, dental or HVAC business, a good share of your leads probably arrive as a phone call, not a form. That one fact changes how a first Google Ads account should be built. For the wider choice of channel and budget, start with our guide to digital advertising for US small businesses.

Why calls, not clicks, are the number to set up first

Clicks are the least useful number in the account. A click tells you someone landed on a page, not whether the phone rang.

If your business takes work by phone, an account with no call tracking shows what you spent and how many people clicked, but not which keywords produced a booked job. You end up judging it by how busy the phones feel.

In our view, the first hour of a new account belongs to conversion tracking, not ad copy. Our rule: nothing gets budget until a test call and a test form both show up in Google Ads as conversions. A campaign you cannot measure is not a cheap experiment. It is an expensive guess.

How do you track calls and form fills before you spend?

Google’s set-up guide starts in the Goals menu: Summary, then create a conversion action, then tick conversions from phone calls, as described on Google’s phone call conversions page. It then asks which kind of call to measure.

• Calls from ads. Google says this identifies which specific ads drive leads directly. It relies on a call asset, and you can count only calls longer than a minimum duration you set, per Google’s page on measuring calls from ads.
• Calls from your website. Google says this tracks customers who visited your site before calling.

Most service businesses should set up both, with a minimum call length chosen before launch that filters out wrong numbers and hang-ups.

Google also notes that a new phone call conversion action can show as unverified or inactive until Google Ads records the first real conversion or a successful test event. So a status warning on day one is not a fault. Make a test call from a phone that is not yours and confirm it appears.

Form fills need a conversion action that fires only on the thank-you step, never on the page that merely shows the form. Keep one action per kind of lead, so you can later see whether calls or forms are doing the work.

Which ZIP codes should the campaign actually show in?

Targeting a whole state or metro area is the easy default and, for most service businesses, the wasteful one. Clicks from the far side of the metro are money for jobs you will decline.

Google lists postal code as a location target type for the US, with the example 76622, US, on its location target types by country page. Its location targeting article says Google only permits targeting for locations that meet minimum privacy thresholds, and does not allow radius targeting under 1 km (about 0.6 miles) around any given location.

Our approach: add the ZIP codes where you take jobs today and leave the rest out. Widening later is cheap; narrowing later means you already paid for the clicks you did not want.

Presence or interest: pick the one that matches how you take work

Google’s location settings have two modes. Its location article describes “Presence or Interest” as reaching people who are in your target locations and also people who have shown interest in them, and “Presence” as reaching only people physically in the selected locations. Google’s help page on location options states that the default uses both physical location and location of interest.

For a local trade, that default means someone in another state researching a move to Columbus can see your ad, and an HVAC company cannot service them. We would switch to Presence only. Google itself suggests Presence when you only want to reach people in those specific places. The exception is a business selling to people planning a move or trip, where interest in the place is the point.

What the account time zone controls, and why you cannot undo it

Beginners pick this setting in a hurry. Google’s time zone page says your reports and statistics follow the time zone you select, so every day-by-day and hour-by-hour view, and the ad schedule you write against it, runs on that clock. Billing pages are the exception: Google shows them in Pacific time whatever you choose.

The sharp edge: Google says time zone changes are no longer supported in standard serving accounts. For a different one, you create a new account. Campaigns can be copied across, but the history does not follow.

For a US business this bites in two ways. A company serving more than one time zone has to choose one clock for the account and write its ad schedule against it. And an account created by a contractor on the opposite coast may be on the wrong clock without anyone noticing. Check it before you build a schedule.

Do you need a campaign type other than Search?

Not at the start. Google will offer guided Smart campaigns and Performance Max, and both can work. But a beginner is better off with plain Search, because you can see the actual searches that triggered your ads, and that vocabulary is the first month’s real lesson. We would hold the automated types back until tracking has recorded real conversions, because automation optimizes toward the signal you give it, and a missing or noisy signal teaches it the wrong lesson at speed.

A licensed trade should check Local Services Ads eligibility before spending on Search. Our pillar guide explains how to weigh them.

What will Google ask for, and what will the bill include?

Two administrative surprises are worth knowing about before you enter a card.

Advertiser verification. Google’s advertiser verification page says that when your account is selected, some of your ads may be restricted, and Google may pause the account if you miss the deadline in your notice. Status can take up to 5 business days to update after you submit.

Its US document requirements say an organization may need registration documents, such as IRS-issued notices, state incorporation certificates or business credit reports, plus a government-issued photo ID from an authorized representative. Digital IDs are not accepted. Make sure the business name on your billing profile matches those documents.

Sales tax. Google’s taxes page says Washington State began applying sales tax to digital advertising services on October 1, 2025, and that Google began collecting it from January 1, 2026. It says individual states have local taxes based on the customer billing address, assessed and charged at the end of each month. Google states that it cannot provide tax advice, so ask your accountant what applies to you.

A first month for a Columbus HVAC company (hypothetical)

This is a hypothetical business with assumed numbers, not a client and not a result.

A heating and air-conditioning company in Columbus, Ohio, sets a budget of US$1,500 a month. Before the budget is switched on, it does five things in this order:

1. Sets the account time zone to Eastern, because it cannot be changed later.
2. Creates two conversion actions, calls from ads and form submissions, and confirms a test call and a test form both show.
3. Targets the ZIP codes it services, with location set to Presence only.
4. Builds one Search campaign around emergency repair, with negatives such as jobs, careers, DIY and free.
5. Checks verification and billing details so a mismatch does not pause the account in week one.

The arithmetic is the part most beginners skip. Google’s Target CPA page says: “For evaluation, we recommend you measure performance for the last 30 days, including at least 30 conversions.” Divide US$1,500 by 30 and you get US$50. If a counted call or form costs this company more than US$50, it will not reach 30 conversions in a month, so it must raise the budget or accept a slower read. Until then, a bad first week is not proof, so it sets its stop condition before launch and reviews at 30 days.

Before committing, the owner should find the break-even cost per click in our Google Ads cost guide and run the budget through our free Google Ads budget calculator.

When the honest answer is not yet

Not every business should start this week. We would wait if any of these is true:

• You cannot answer the phone or call back within the hour. Paid clicks that reach voicemail are expensive.
• You will not log calls and forms, which makes tracking wasted.
• Your Google Business Profile is thin. That is the cheaper first step, and our local SEO guide covers it.
• Your offer is visual rather than searched for. Meta ads usually fit that better.

Waiting a month to fix those costs far less than finding them out on a live budget. If you want the account built and read for you, see our digital advertising service.

Frequently asked questions

Do I need a website to run Google Ads for my small business?

You need somewhere for the click to land, and in our view that should be a page on your own site with your phone number and a short form on it. A page you control is also where the Google tag sits, so it is where tracking lives.

How do I track phone calls from Google Ads?

Create a conversion action for phone calls under Goals, then choose calls from ads, calls from your website, or both. Calls from ads need a call asset, and Google lets you count only calls that last longer than a minimum length you set. Calls from your website need the Google tag plus a phone number snippet on the page. Test it with a real call before you spend.

Can I target specific ZIP codes with Google Ads?

Yes. Postal code is a location target type in the US. Google only allows targets that meet minimum privacy thresholds, and it does not allow radius targeting under 1 km (about 0.6 miles), so check that each ZIP code you want is accepted.

Can I change the time zone on my Google Ads account?

Not in a standard account. Google says time zone changes are no longer supported in standard serving accounts. If you picked the wrong one, the route is a new account with the right time zone, and campaigns can be copied across, but the history stays behind in the old account.

Will Google charge sales tax on my ad spend?

It can. Google’s help page says Washington State began applying sales tax to digital advertising services on October 1, 2025, and that Google began collecting it from January 1, 2026. It also says individual states have local taxes based on your billing address, charged at the end of each month. Google says it cannot give tax advice, so ask your accountant.

Do I have to be verified before my ads can run?

Verification is triggered by Google, not chosen by you. Google says that when your account is selected, some ads may be restricted until you finish, and it can pause an account that misses the deadline. A US organization may be asked for registration documents plus a government photo ID from an authorized representative, so have them ready.
