If you run a local business, showing your Google Ads to everyone in a large city or region can waste part of your budget.
You may only serve customers within 10, 20, or 30 kilometers of your business. Or you may want to reach people around a store, event venue, service area, or another specific location.
This is where how to use geofencing for Google Ads becomes an important search topic.
There is one important clarification, though. Google Ads does not offer a separate campaign setting officially called “geofencing.” Instead, Google provides location targeting, radius targeting, location exclusions, and other geographic controls. Radius targeting, also called proximity targeting, lets you choose a distance around a location where your ads can be eligible to show.
Many marketers refer to this type of hyperlocal targeting as geofencing Google Ads.
In this guide, you will learn how to set up geographic targeting, use a radius around a location, choose the right location settings, use geofencing on Google Ads for local campaigns, and avoid common targeting mistakes.
Geofencing usually means creating a virtual geographic boundary around a physical area and using that boundary to control advertising or audience targeting.
In Google Ads, the closest built-in option is radius or proximity targeting.
For example, suppose you own a phone repair shop in Oakville.
Instead of targeting all of Ontario, you could create a radius around your business and focus your ads on people within the distance that makes sense for your service area.
Google Ads allows advertisers to target countries, regions, cities, postal areas where available, business locations, and a radius around a location.
So when someone searches for geofencing Google Ads, they are often referring to this type of location-based campaign setup.
Not exactly.
Traditional geofencing can refer to technology that creates a virtual boundary and triggers an action when a device enters or leaves that area.
Google Ads location targeting works differently. Google uses signals such as device information, user settings, and behavior to determine whether someone meets the campaign’s location criteria. Google states that location targeting is an estimate and is not guaranteed to be 100% accurate.
This distinction matters when planning a campaign.
You should not assume that drawing a radius in Google Ads creates a perfect physical fence around a building.
Location targeting can be useful when your business depends on where customers are located.
For example:
The goal is simple:
Spend more of your advertising budget in locations that can actually produce customers.
Google also recommends reviewing geographic performance so advertisers can allocate advertising and budget toward locations where campaigns perform better.
If you want to use Google Ads for hyperlocal targeting, the process starts with your campaign’s location settings.
Before opening Google Ads, define the geographic area that matters to your business.
Ask:
For example, a local restaurant may only deliver within 8 kilometers.
A plumber may serve a 25-kilometer area.
An ecommerce company may serve an entire country.
There is no universal radius that works for every business.
The targeting should reflect the actual customer journey.
Create or open the campaign where you want to apply location targeting.
Your options can vary depending on the campaign type and country.
Google Ads supports geographic targeting across several campaign types, but the exact location options available can differ.
For example, you may use location targeting for:
The important thing is to check the location options available for the specific campaign you are creating.
In Google Ads, go to the campaign you want to edit.
Then open the location settings.
Google’s current setup path includes:
Campaigns → Audiences, keywords, and content → Locations
From there, you can add locations to the campaign.
The exact interface can change over time, so your account may display slightly different navigation.
If you want to target customers around a specific location, choose the radius option.
Google’s current instructions allow you to:
For example:
Business location: 123 Main Street
Radius: 15 km
Your campaign can then use that geographic target as part of its eligibility for ad delivery.
Google currently requires a minimum radius of 1 kilometer for radius targeting because of privacy thresholds. Very small geographic targets may also receive limited or intermittent ad delivery.
This is one of the most important parts of geofencing on Google Ads.
Google Ads can use different location signals and settings to determine who qualifies for your location targeting.
Depending on the campaign and available settings, you may encounter options involving people who are:
Google explains that location targeting can include both physical presence and location-of-interest signals, while advanced options can allow advertisers to narrow this behavior.
If your business specifically needs customers who are physically in an area, review the available presence-based setting carefully rather than assuming the default is ideal.
This can matter for businesses such as local stores, restaurants, clinics, and event campaigns.
Geographic targeting is only half of the process.
You should also consider where you do not want your ads to appear.
For example, suppose a home service company operates throughout one region but does not serve a particular city.
You can target the wider service area and exclude that city.
Google Ads supports location exclusions to prevent ads from showing in selected geographic areas.
This can help reduce wasted impressions and clicks.
Always look at the map after creating a radius.
Ask:
A 20-kilometer radius may look reasonable on paper but can cover very different markets depending on the location.
Do not choose a radius simply because another business uses the same number.
There is no perfect radius for every Google Ads campaign.
The right distance depends on your business model.
A smaller radius may make sense because customers can visit the physical location.
The appropriate area may depend on whether customers visit the restaurant or use delivery.
A larger radius may make sense if technicians regularly travel to customers.
A smaller geographic area may work if most patients come from nearby communities.
A radius may not make sense at all if you ship throughout a country.
Google recommends choosing location targets based on where your customers are, which is not always the same as where your business is physically located.
If you already have customer information, use it to guide your targeting.
Review:
For example, if most qualified leads come from within 15 kilometers of your business, that information may be more useful than choosing a random 30-kilometer radius.
The phrase geofencing Google Display Ads usually refers to using geographic targeting to show Display ads to audiences in selected areas.
Google’s Display Network includes websites, apps, videos, Gmail, and other inventory. Google explains that location can be used as one of the signals for serving Display ads.
For example, a local furniture store could create a Display campaign targeting its service area.
The campaign could then use:
The key is not to treat location as the entire targeting strategy.
A large radius combined with weak audience targeting can still produce irrelevant traffic.
Imagine a business selling premium gym equipment in Toronto.
Instead of advertising across Canada, the business could target an area around its showroom or selected service locations.
The campaign could use:
Location: Selected geographic area
Audience: Fitness-related audience segments
Creative: Local showroom offer
Landing page: Toronto showroom page
Conversion: Store visit enquiry or lead form
This creates a more focused campaign than simply targeting an entire country.
Search campaigns are especially useful when geographic targeting is combined with search intent.
Suppose a person searches:
phone repair near me
If your repair shop serves that area, geographic targeting can help make your campaign more relevant.
You can combine:
The person provides the search intent, while geographic targeting helps narrow where the campaign can show.
This is often more useful than treating location targeting as a standalone tactic.
Local businesses can use radius targeting in several ways.
Target customers within a practical distance of the restaurant.
You can then use location-focused ad copy and send users to a relevant menu or booking page.
A phone repair shop can target people near its store and advertise services such as:
The radius should reflect how far customers are realistically willing to travel. A Google Ads agency for phone repair can help you in placing the geofencing around your service area.
A dental practice can target the communities that generate its patients.
It can then use location-specific landing pages and ads where appropriate.
Plumbers, electricians, cleaners, HVAC companies, and other service businesses can use geographic targeting to focus on areas they actually serve.
Google specifically identifies businesses that serve a selected radius as a potential use case for radius targeting.
This is where expectations need to be realistic.
Google Ads allows radius targeting around a location, but that does not mean you can create any custom-shaped boundary around an individual building and guarantee that ads will only reach people inside that boundary.
Google’s official location targeting options include geographic areas and radius targeting. Google also notes that its location targeting relies on multiple signals and cannot guarantee 100% geographic accuracy.
So if someone asks:
Can I draw an exact custom fence around one building in Google Ads?
The answer is generally no through standard Google Ads location targeting.
A radius around the location is the closer built-in option.
You can use geographic targeting around an event location when the campaign and available targeting options support it.
For example, suppose a business wants to advertise to people in the area around a conference venue.
A radius around the venue can be used as a geographic target.
However, do not describe this as a guarantee that every person physically inside the venue will see the ad.
Google’s location system uses multiple signals, and location targeting is not 100% precise.
For event marketing, combine location with appropriate campaign targeting, creative, timing, and measurement.
Location alone does not tell you everything about a potential customer.
Two people can be in the same area but have completely different interests and purchase intent.
You can therefore combine geographic targeting with relevant audience signals where the campaign type supports them.
For example:
Location: 10 km around a fitness store
Audience: Fitness-related audience
Creative: Local promotion
Landing page: Store-specific page
This creates a more focused campaign than relying on geographic targeting alone.
Setting up the radius is only the beginning.
You need to measure what happens after people see or click your ads.
Track metrics such as:
For local businesses, also review performance by location.
Google provides geographic performance reporting that can help advertisers understand how different areas perform. Google also provides distance reports for eligible Search and Shopping campaigns.
For example, you might find:
| Distance from business | Clicks | Leads | Cost per lead |
| 0-5 km | 120 | 14 | $18 |
| 5-10 km | 180 | 15 | $24 |
| 10-20 km | 250 | 10 | $42 |
| 20+ km | 300 | 4 | $76 |
This type of data can help you decide whether your current geographic targeting matches actual customer behavior.
The numbers above are only an example, not a benchmark.
After your campaign has collected enough data, review performance by location.
You may find that:
Google recommends using geographic performance information to help allocate advertising effort and budget across locations.
Do not make major changes based on a handful of clicks.
Look for meaningful patterns.
A 10-kilometer radius is not automatically better than a 30-kilometer radius.
Base the distance on customer behavior and your actual service coverage.
Google clearly states that location targeting uses several signals and is not guaranteed to be completely accurate.
Treat the radius as a targeting control, not a perfect physical boundary.
Very small targets may have limited reach.
Google notes that small geographic targets may cause ads to show intermittently or not at all because they may not meet targeting criteria.
If there are areas you cannot serve, consider excluding them.
Otherwise, part of your budget may go toward users who cannot become customers.
Review the available location options carefully.
Someone interested in a location is not necessarily physically there.
The right setting depends on what you are trying to accomplish.
A local business does not always need to target an entire province, state, or country.
Use the smallest practical area that gives the campaign enough useful reach.
A location that produces many clicks is not necessarily your most valuable location.
Look at leads, sales, revenue, and customer quality where possible.
The terms are often used interchangeably, but they can describe different ideas.
Geotargeting is the broader practice of targeting advertising based on geographic location.
Geofencing usually refers to creating a defined geographic boundary around a place and using that boundary for advertising or audience purposes.
In Google Ads, the official terminology focuses on location targeting and radius or proximity targeting.
For practical Google Ads work, the important question is not which term you use.
The important question is:
Which geographic targeting option gives the campaign access to the customers it can actually serve?
Before launching a location-focused campaign, check the following:
A phone repair shop was running Google Ads across a large geographic area.
The campaign generated clicks, but many enquiries came from people who lived too far away to visit the shop.
The problem was not simply the ad copy. The geographic targeting did not match the business’s practical service area.
The campaign was restructured around the shop’s actual customer area using radius targeting. Locations outside the service area were reviewed and excluded where appropriate.
The campaign also used service-specific ads and conversion tracking to measure repair enquiries.
The result was a clearer connection between the advertising area and the customers the business could realistically serve.
The example illustrates the main purpose of location targeting: aligning ad reach with the geographic area where your business can actually deliver its product or service.
Geographic targeting can be useful when location has a direct relationship with your customers.
It can make sense for:
It may be less useful for businesses that sell nationally or globally without geographic restrictions.
Before creating a small radius, ask whether location actually influences the customer’s decision.
Location targeting is Google’s official advertising terminology for selecting geographic areas where ads can be eligible to show. Geofencing is a broader marketing term often used for advertising based on a defined geographic boundary. In Google Ads, radius targeting is the closest standard feature to this concept.
Learning how to use geofencing for Google Ads starts with understanding what Google Ads actually offers.
Google Ads provides location targeting and radius or proximity targeting rather than a separate geofencing product. These tools allow advertisers to focus campaigns on selected geographic areas and exclude locations that do not make sense for the business.
The best approach is to start with your real service area, choose a practical radius, review location settings, track conversions, and use performance data to refine your targeting.
Do not assume a smaller radius automatically produces better results. The right geographic setup is the one that gives your campaigns access to enough relevant customers while keeping your advertising aligned with the areas your business can serve.
For businesses that need help with local Google Ads campaigns, Web Market Solution provides Google Ads and digital marketing services for businesses in Canada. Geographic targeting can be reviewed as part of a broader campaign strategy that includes keywords, ad copy, landing pages, conversion tracking, and budget management.
Google Ads does not use “geofencing” as a separate standard campaign product. Its location targeting features include geographic locations and radius or proximity targeting, which are commonly used for what marketers describe as geofencing.
Google currently does not allow radius targets below 1 kilometer. Very small geographic targets can also have limited or intermittent ad delivery because of Google’s targeting and privacy requirements.
Yes. Google Ads supports radius targeting around a selected location. You can enter a location, choose the radius and unit of measurement, review the map, and save the target.
Yes. Google Ads supports location exclusions, which can help prevent ads from showing in selected geographic areas.
No. Location targeting uses multiple signals, and Google states that geographic accuracy is not guaranteed at 100%. Other campaign factors also affect whether an ad is shown.
You can use geographic location targeting with supported Display campaigns. Google states that location information can be used as a signal for serving ads across the Display Network.
