The simple answer

Google Ads location targeting controls the geographic areas where your ads may appear. You can target countries, states, cities, ZIP codes, or a radius around an address.

Google Ads location targeting controls the geographic areas where your ads may appear. You can target countries, states, cities, ZIP codes, or a radius around an address.

The important part is not simply adding the places you serve. You also need to check Google's advanced location setting, exclude places you do not serve, and measure which areas produce calls, customers, and revenue.

The Simple Answer

For most local service businesses, a sensible starting setup is:

  1. Target only the cities, ZIP codes, or service area you can actually cover.
  2. Use the option focused on people who are in or regularly in those locations.
  3. Exclude nearby areas you cannot serve.
  4. Check the location report for clicks from unexpected places.
  5. Split out important markets when they need different budgets, ads, or landing pages.

Google's default location option can include people who have shown interest in a place even when they are not physically there. That can be useful for hotels, travel, real estate, and some destination businesses. It can also waste money for a plumber, garage door company, or other business that must send a person to the customer's address.

What Google Ads Location Targeting Does

Location targeting tells Google where you want to find potential customers. Common choices include:

Google uses signals such as a person's device, settings, internet connection, and recent behavior to estimate location. It is not perfectly accurate. Treat location targeting as a control that needs checking, not a wall that can never leak.

The Location Setting Most Local Businesses Should Check

Google offers advanced location options. The wording can change, but the choice normally separates:

The second option reaches more people. For a local service company, that extra reach can include someone outside the service area who searched for the city, researched a move, or showed another location signal.

If the business can only serve customers physically inside the target area, start with the presence-focused option. If customers commonly buy before arriving in the area, test the broader option separately.

City, ZIP Code, or Radius Targeting?

There is no single best choice. Use the smallest setup that reflects how the business actually works.

Targeting methodUseful whenMain risk
CityThe whole city is serviceableCity borders may include areas you do not want
ZIP codeService boundaries are specificToo many small targets can become hard to manage
RadiusThe business serves a set distance from a shop or officeA circle rarely matches drive time or real service boundaries
State or regionThe business can sell or deliver broadlySpend may flow toward large, weak areas

A radius is easy to set up, but a 25-mile circle does not account for traffic, bridges, mountains, or technician routes. ZIP codes or city groups can be more practical when serviceability is uneven.

A Simple Local Service Example

Suppose an HVAC company serves Dallas and nearby suburbs but does not send technicians to Fort Worth.

A weak setup might target the entire Dallas–Fort Worth area. It produces 1,000 clicks at $8 each:

1,000 clicks × $8 = $8,000 in spend

If 150 clicks came from places the company cannot serve, then:

150 clicks × $8 = $1,200 spent outside the usable service area

The exact fix is not always to remove every low-performing location. First check whether the issue is true serviceability, poor tracking, a weak landing page, or simply too little data. But a click from a place the business refuses to serve has almost no chance of becoming revenue.

How to Set Up Location Targeting

In Google Ads:

  1. Open the campaign.
  2. Go to the campaign's location settings.
  3. Add the cities, regions, ZIP codes, or radius you want to target.
  4. Add exclusions for places you do not serve.
  5. Open the advanced location options.
  6. Choose the option that matches how customers buy from you.
  7. Save the changes.

Google's interface changes over time. The names may move, but the core choices remain the same: where to target, where to exclude, and whether location interest should count.

When to Split Locations Into Separate Campaigns

Do not build a new campaign for every ZIP code. Separate locations when the split gives you a useful control.

Create separate campaigns when locations need different:

For example, a company opening a new market may want a separate campaign so the new area cannot consume the budget needed by the established market. Darlington's guide to service-area expansion explains how to stage that decision.

Match the Ad and Page to the Location

Location targeting decides who may see the ad. The ad and landing page still need to make the location clear.

A useful path looks like this:

Do not add a city name to an ad or page unless the business genuinely serves that city. Use the Google Ads landing page guide to keep the search, ad, and page aligned.

How to Check Whether the Targeting Works

Review geographic performance regularly. Look beyond clicks.

For each meaningful area, compare:

One city may deliver cheap leads that never become customers. Another may have a higher cost per lead but produce larger jobs and more revenue.

Accurate Google Ads conversion tracking is required before these comparisons become trustworthy.

Common Location Targeting Mistakes

Leaving the Default Setting Unchecked

The campaign may reach people interested in the target area, not only people located there.

Targeting a Whole State for Convenience

A broad map is easy to build and expensive to learn from. Match the targeting to the actual service area.

Forgetting Exclusions

Nearby cities, states, or ZIP codes can produce irrelevant clicks. Add clear exclusions where needed.

Making the Area Too Small

Very narrow targets may not produce enough searches for the ads to show consistently. Combine nearby areas when they share the same business rules.

Judging Locations by Leads Alone

Lead counts can hide poor quality. Use customers and revenue whenever possible.

Can Google Ads target ZIP codes?

Yes, in supported countries. Availability and accuracy vary, so review actual location performance after launch.

Can I target a radius around my business?

Yes. Radius targeting is useful when customers are normally served within a set distance, but a circle may not reflect actual travel time or service boundaries.

Why am I getting clicks from outside my target area?

Possible causes include the advanced location setting, Google's imperfect location signals, closely related areas, or a report showing a person's location of interest rather than physical location. Check the campaign setting and geographic report before changing the campaign.

Should every city have its own campaign?

No. Split cities only when you need separate control over budget, services, ads, pages, or performance goals.

Should I use location bid adjustments?

Only when the campaign's bidding method supports them and the data shows a meaningful difference. Do not use a bid adjustment to compensate for a location the business should not target at all.

The Bottom Line

Good location targeting protects the budget from clicks the business cannot turn into customers. Start with the real service area, check the advanced location option, exclude unusable places, and judge each area by customers and revenue.

More map coverage is not automatically more growth. The goal is to show ads where the business can actually win the work.
