Geofencing Ads: How They Work and What Local Businesses Need

Geofencing ads show your message to people on their phones when they are inside, or have recently been inside, a map area you choose. That area might be a two-block radius around your restaurant, a competitor’s parking lot, a hospital campus or a downtown festival. For a local business in Metro Vancouver, they can be a precise way to reach nearby customers. They can also waste money fast when the area, the offer and the measurement are not planned together.

This guide covers what geofencing advertising is, where you can run it, which businesses it suits, how to set up and measure a campaign, and the Canadian privacy rules that apply to location data.

TL;DR

• A geofence is a virtual boundary around a real place. Ads are shown to mobile devices that enter it, using GPS, Wi-Fi or mobile network signals to estimate location.
• You do not need special software to start. Google and Meta both let you target ads to a radius or a set of places, and that covers most small business needs.
• Judge a campaign on visits, calls and orders, not clicks. Where the tools allow it, compare people who saw the ads with a similar group who did not.
• Canadian privacy law treats precise location as sensitive. Collect only what you need, be open about it, and use a platform or partner that is clear about how data is handled.
• The tightest geofence is not always the best one. Offer, timing and the page people land on usually decide the result.

What geofencing ads are

A geofence is a virtual boundary drawn around a physical location. Geofenced ads are location-based advertisements that can appear on a mobile device when its user enters that boundary, with GPS, Wi-Fi or mobile networks helping identify where the device is.

In practice, people use the term loosely. It covers three things:

1. True geofencing: ads triggered by a device being inside a tight boundary around a specific building or site.
2. Radius targeting: ads shown to people in a circle around an address, which is how most small businesses actually run it.
3. Place or area targeting: ads shown to people in a neighbourhood, a postal area or a list of selected locations.

The differences matter because they change cost, precision and the privacy questions you have to answer. A restaurant in Burnaby that wants lunchtime orders from nearby offices does not need a polygon traced around a single tower. A radius that matches how far people will actually walk or drive for lunch does the job.

How geofencing advertising works

The sequence is simple. You define a location and an audience. The ad platform estimates where users’ devices are, using signals such as GPS, Wi-Fi and mobile networks. When a device matches your location rule, it becomes eligible to see your ad, subject to the auction, your budget and your targeting settings.

Two details are worth knowing.

First, location is an estimate. Accuracy varies with the signal, the device and the setting. Dense areas like downtown Vancouver, where towers are close together and buildings block signals, are harder to pin down than a suburban strip mall in Langley.

Second, platforms distinguish between where someone is and where someone has shown interest. Google Ads, for example, lets you choose countries, cities, a radius around a location, or your own Business Profile locations. Some campaign types also offer a choice between people physically present and people who have shown interest in an area. Read that setting carefully. If you want the person standing on Granville Street and not the person who searched for it from Toronto, choose accordingly.

Where you can run geofencing ads

You have three practical routes.

Google Ads

Google lets you target by radius, by city or area, or by your Business Profile locations. This works well for people who are actively searching, such as someone typing “sushi near me” or “emergency plumber” from a specific part of town. If you have a connected Business Profile, our Google Business Profile management work and your ad locations should be kept consistent, because the same address and hours show up in both places.

Meta (Facebook and Instagram)

Meta lets you target people in or near a location, with a radius you set. It suits visual, impulse-driven offers: a new menu item, a seasonal promotion, a grand opening, a limited-time package. Because people are scrolling rather than searching, the creative has to do more of the work.

Specialist mobile advertising providers

Some providers sell tighter, event-based or competitor-site geofencing across mobile apps and websites. These can suit larger budgets or specific goals, such as reaching attendees at a trade show. For most local businesses, the built-in tools on Google and Meta are enough to start. Small and medium-sized businesses can run location-based ads through Google or social media without building a custom app.

If you want a team to set up and run Google and Meta campaigns for you, that is what our Google and Meta ads management covers.

Which local businesses benefit most

Geofencing works best when a short trip is part of the buying decision and the customer is near the location at the moment of choice.

Restaurants and online orders

For a restaurant, the goal is usually to move customers toward ordering. The choice is whether they order through a delivery marketplace or directly from you. Geofenced ads can send nearby people to either. If margin matters, a direct ordering page avoids marketplace commissions, which is why we build commission-free Clover online ordering for restaurants. If you also sell through DoorDash, Uber Eats or SkipTheDishes, our guide on ranking higher on delivery platforms explains how to keep those listings working for you.

Ads are only half of local visibility. People who see your ad will often check your Google Maps listing before they act, so it is worth reading how to rank your restaurant higher on Google Maps alongside any ad plan.

Multi-location brands

If you run several locations across Vancouver, Burnaby, Richmond or Surrey, define a separate geofence for each one, with its own address, hours, offer and landing page. A shopper in Coquitlam should not see a promotion for a store in Delta. Keep the radii from overlapping unless you want the locations to share the same audience, and review each location’s results on its own before you judge the whole brand.

How to set up a geofencing campaign

1. Pick one outcome

Decide what a good result looks like before you open an ad account. Phone calls, direction requests, online orders, bookings and in-store redemptions each need different ads and different tracking. Choosing several at once makes the results hard to read.

2. Draw the area from real behaviour

Look at where your current customers come from. A coffee shop might draw most of its trade from a ten-minute walk, while a furniture showroom might draw from across the Lower Mainland. Start with the distance people really travel, not the largest radius your budget can afford. Then add exclusions for areas you cannot serve, such as places outside your delivery range.

3. Choose the audience and timing

Location is only one filter. Combine it with the hours your business is open, the days that matter, and, where it is useful, language or interest signals. A lunch offer shown at 9 p.m. is wasted spend.

4. Write the ad for the place

Ads that mention the neighbourhood, the street or a nearby landmark tend to feel relevant. Keep the offer specific and the next step obvious: order now, call, get directions, book.

5. Build a landing path that matches

Sending a geofenced ad to a generic home page loses people. Send it to the page that finishes the job: the ordering page, the booking form, the location page with a map. Make sure the page loads fast on a phone and that your hours and address are right. Our web design and development work handles this link between ad and site, including ordering and POS integration.

6. Launch small, then adjust

Run a modest budget for a few weeks, look at what the data says, and then change one thing at a time: radius, offer, creative or hours.

How to measure whether geofencing is working

Clicks are the easiest number to read and the least useful. A better measurement plan looks at what happened in the real world:

• Orders and bookings tracked to the ad, through your ordering system or booking tool.
• Calls and direction requests, which both Google and Meta can report.
• Visits, where the platform’s tools provide them and the volume is large enough to report.
• Redemptions, using a code, a phrase to mention or a distinct offer for each campaign.

The harder question is whether the ad caused the visit or the person was coming anyway. Geofencing targets people who are already nearby, so some of them would have bought regardless. The cleanest check is to compare a group exposed to the ads with a similar group that was not, then look at the difference in visits or orders. That is the idea behind incremental lift. Few small businesses can run a formal test, but you can approximate one: pause the ads in one comparable area, keep them running in another, and compare orders over the same weeks.

Keep a simple monthly record of spend, orders, calls and cost per order. If an area produces no extra orders after a fair test period, reduce it or change the offer before spending more.

Privacy rules in Canada: what to know before you launch

Location data is among the most sensitive information an advertiser touches, and Canadian regulators have said so clearly. This is general information, not legal advice. If you collect location data yourself, or work with a provider that does, ask a privacy lawyer to review your setup.

Precise location is sensitive

In a joint investigation of Tim Hortons’ mobile app, the Office of the Privacy Commissioner of Canada (OPC) and provincial regulators found that collecting vast amounts of sensitive location data for targeted advertising was inappropriate and disproportionate to the benefits. The same findings stress that consent must be meaningful and understandable, and that consent cannot make an otherwise unreasonable tracking purpose lawful.

For businesses, the OPC’s follow-up guidance says that granular geolocation is sensitive personal information. It advises that you collect only what you legitimately need, explain what is collected, why, and who receives it, and generally obtain express opt-in consent where the purpose is unexpected or the data is sensitive. It also raised concern about vague contract wording that could let a third-party provider use customer data for its own purposes.

What that means in practice:

• If you only use the location targeting built into Google or Meta, the platform handles the location signal and you do not receive individual device data. Use that route when you can.
• If you run your own app or work with a provider that collects location data on your behalf, you need clear consent, a clear purpose and a written contract that limits how the provider may use the data.
• Ask whether a less invasive approach would meet your goal. A neighbourhood-level target is often enough.
• Avoid building audiences around sensitive places or topics, such as health conditions, where inference could cause harm.

Messages that reach a phone: CASL

Canada’s Anti-Spam Legislation applies to commercial electronic messages. The CRTC says these require consent, sender identification and an unsubscribe mechanism. It also notes that CASL may apply to commercial push notifications shown outside an app, and that an exemption may be unavailable when third-party ads make the sender hard to identify and the messages hard to disable.

Plain display ads on Google or Meta are a different thing from texts, emails or push notifications you send yourself. If your plan involves messages sent directly to people’s phones, confirm consent and unsubscribe handling first.

Perspective: where geofencing fits in a local marketing plan

We see geofencing ads as a tactic, not a strategy. Businesses come to us after paying for a tight radius and getting clicks that go nowhere, and the cause is rarely the geofence. It is usually one of three things: the Google Business Profile is out of date, the landing page is slow or confusing on a phone, or nobody can tell which orders came from the ad.

Our view is that the ad is the last step of a chain. Someone nearby sees your offer, checks your listing, reads a few reviews, opens your site and then orders or calls. If any link is weak, a precise audience just means you pay more to disappoint the right people. That is why we prefer to work on the listing, the site, the ordering path and the ads together, with one team accountable for the result, and report in plain language so you can see what each piece did.

For most local businesses we would start with a modest radius on Google and Meta, a clear offer and proper tracking, and only consider more specialized geofencing once those basics produce results worth scaling.

Common mistakes to avoid

• Radius too small. A tiny circle may reach very few people, so the platform has little room to find buyers and the cost per result climbs.
• Radius too large. A wide circle turns geofencing into ordinary local advertising at a higher cost than necessary.
• Ignoring where people live and work. Daytime and evening populations differ. A business district empties after 6 p.m.
• Overlapping zones. Multi-location brands that overlap zones end up bidding against themselves.
• No landing path. An ad that drops people on a generic home page throws away the benefit of knowing they are close.
• Counting clicks as success. Measure orders, calls and visits.
• Treating privacy as an afterthought. Decide what data is involved before launch, not after a complaint.

FAQ

What are geofenced ads?

Geofenced ads are location-based ads shown to mobile devices when their users enter, or are in, a boundary you define. Location is estimated from signals such as GPS, Wi-Fi and mobile networks. Most small businesses run them as radius targeting on Google or Meta.

Can I run my own geofencing campaign?

Yes. Google Ads and Meta both let you target a radius or selected areas without custom software, and a small budget is enough to test. The harder parts are choosing a sensible area, writing a relevant offer, building a landing page that works on a phone, and tracking results. If you do not have time for those, an agency can run it for you.

Are geofencing ads legal in Canada?

Location-based advertising is lawful, but it is subject to Canadian privacy law and, for direct messages, CASL. The Privacy Commissioner treats precise location as sensitive information, so collect only what you need, be transparent and get meaningful consent where you collect data yourself. For a specific setup, ask a privacy lawyer.

How can I tell if geofencing ads are working?

Look at orders, calls, bookings and redemptions rather than clicks. Where you can, compare an area with ads to a similar area without them, so you see the extra business the ads created. Give a test a few weeks before you decide.

Can people avoid geofencing ads?

Yes. Users can turn off location services for apps, limit ad personalization in their device and account settings, or reset their advertising ID. Because of that, no geofenced audience is complete, and results should be judged on actual outcomes.
