You configured your Google Ads to target your city and the surrounding area. You drew a radius on the map or selected your zip codes. You assumed, reasonably, that your ads would only show to people in that area.
That assumption is not accurate, and it is costing you money.
Geographic waste is one of the most consistent problems I find in local service business accounts. For an auto repair shop, it looks like this: a driver 35 miles away clicks your ad, presumably because they saw “auto repair” and your shop appeared in their results. They will not drive 35 miles for an oil change. That click is gone, and so is whatever it cost.
The scale of this problem varies by account. Some shops lose 10 to 15 percent of their ad budget to out-of-area clicks. Others lose more. In a market where clicks cost 10 to 18 dollars each, even a 12 percent geographic waste rate on a 1,500-dollar monthly budget is 180 dollars per month in spend that produces nothing.
The Setting Most Owners Never Check
When you set geographic targeting in Google Ads, there is a second setting, often overlooked, that controls how Google interprets your targeting. It is typically labeled “Location options” in the campaign settings.
This setting presents two choices:
“Presence” or “People in your targeted locations”: shows ads to people who are physically in the area you specified.
“Presence or interest” or “People in, regularly in, or who’ve shown interest in your targeted locations”: shows ads to people who are in the area, but also to people who have shown any kind of interest in that location.
The second option sounds reasonable. In practice, “interest” is interpreted broadly enough to include people who read a news article about your city, people who searched for a business in your area while visiting from elsewhere, and people whose internet service provider routes their traffic through an address in your region even though they are not there.
Most accounts are set to the second option, either because it was the default when the account was created, or because an automated setup process selected it without explanation. Nobody changed it. The shop owner had no idea it existed.
Switching to the first option alone typically reduces geographic waste by 5 to 15 percent. It is a small setting change with a real budget impact.
Why Radius Targeting Is Not a Hard Boundary
A second misconception: setting a 20-mile radius creates a strict wall that no ad impression crosses. This is not how it works.
Google determines a user’s location using signals that include GPS data from mobile devices, IP address geolocation, and behavioral location history. Each of these has imprecision.
IP address geolocation, in particular, is notoriously approximate. A user’s IP address is often mapped to the nearest large city, or to the headquarters of their internet service provider, rather than their actual physical location. A driver who lives 22 miles from your shop, just outside your 20-mile radius, may be geolocated by IP address to a point inside the radius. Their click goes through.
The practical effect is that radius targeting provides a strong filter, not a perfect one. Some spend outside the radius is inevitable. The goal is to minimize it through correct settings and, where possible, additional targeting layers.
ZIP Code Targeting as an Alternative
For shops with irregular service areas, or situations where the convenient driving radius does not match a geographic circle, ZIP code targeting offers more precise control.
Instead of a circle on a map, you specify the exact ZIP codes you serve. Every ZIP code inside the list is targeted. Everything outside is not. This gives clean geographic boundaries that match actual service area decisions.
The trade-off: ZIP code targeting requires more maintenance. If the service area expands, new codes need to be added manually. A radius adjusts automatically with a single number change. For shops with straightforward circular service areas, radius targeting is simpler. For shops where the natural service area has geographic constraints (a river to the north, an interstate to the east), ZIP codes can be more accurate.
Negative Location Targeting
In addition to adjusting the targeting method and presence setting, negative locations provide a third layer of control.
A negative location is a specific place you tell Google to never show your ads in. If a particular city or town consistently appears in your geographic performance report generating clicks without bookings, adding it as a negative location excludes it explicitly, regardless of whether it falls inside your radius or outside it.
This is especially useful for areas immediately adjacent to your radius boundary. The ambiguity zone at the edges of a radius is where geographic waste concentrates. Explicitly excluding known problem locations is a practical way to tighten that zone.
Reading the Geographic Performance Report
Checking whether out-of-area spending is happening is straightforward. Google Ads provides a geographic report in the campaign data that shows click volume, spend, and conversion data broken down by location.
Pulling this report and sorting by clicks or spend reveals immediately whether a significant portion of the budget is going to locations outside the intended service area. For most shops that have never checked this, the first time looking at this report is revealing. Cities and towns appear in the list that the shop owner would never have expected to see.
The report can be sliced at different geographic levels: country, region, metro area, city, and sometimes ZIP code. The most useful view for a local shop is typically city or ZIP code level, which shows specifically where the money is going.
The Call Quality Connection
Geographic waste is not just a budget leak. It also affects call quality. A driver 40 miles away who calls after clicking your ad may have genuinely found you because they are driving through your area or they are planning to have work done while visiting. But most of the time, they are simply too far away and will not book. They may not even realize how far the shop is when they click.
These out-of-area calls consume phone time, produce no revenue, and if the shop is also tracking calls as conversions in Google Ads, they pollute the conversion data with calls that never produce jobs. The algorithm sees a “conversion” from a click that came from outside the service area. It may start showing more ads in that area because it believes that area is producing results.
The feedback loop from geographic waste is self-reinforcing if tracking is not also monitoring where the conversions are actually located.
Getting This Fixed
Fixing geographic targeting for an auto repair shop is a straightforward part of any account audit. Identifying where the budget is going, correcting the targeting settings, and adding negative locations where needed typically takes under an hour once you know what to look for.
