Google Ads geotargeting is the ability to restrict where your ads appear — by country, province, city, postal code, or a radius around your business address — so that your budget reaches only the people who can actually become your customers. For South African businesses, getting this right is the difference between a campaign that pays for itself and one that haemorrhages spend on searchers hundreds of kilometres away. If you are building or auditing a Google Ads account, the complete Google Ads South Africa guide covers the full strategic picture; the Google Ads costs guide for South Africa puts the spend context around it.
The mechanics of location targeting look simple on screen — a search box, a map, a few radius sliders. What they hide is a default setting that ships with every new Google Ads campaign, one that most SA advertisers never change, and one that quietly routes budget to users who are merely interested in your location rather than actually in it. A Durban plumbing company, for example, can spend on someone in Johannesburg who Googled "Durban plumber" while planning a building project there. That person cannot call you out on a weekend emergency. The default setting makes that spend legitimate by design.
This guide works through every layer of location targeting available for South African campaigns — from national coverage down to a 5 km ring around your shopfront — with a decision table to match your business type to the right setting and a workflow for using Google's own geographic report to find the wasted spend already in your account.
Quick Answer
Google Ads geotargeting lets you show paid ads only in specific geographic areas — from all of South Africa down to a 1 km radius around a single address. The five available targeting levels are country, province/region, city, postal code, and radius. The most important setup decision for SA local businesses is switching the advanced location option from the default "Presence or interest" to "Presence only," which stops ads serving to out-of-area users who merely searched for your location. Layer location bid adjustments (-90% to +900%) on top of your chosen area to push more budget toward the suburbs that actually convert.

Request a Free Location AuditWhat Is Google Ads Geotargeting?
Google Ads geotargeting is the mechanism that connects your campaigns to physical geography — ensuring your ads appear (or don't appear) based on where Google believes the searcher is located or what location they are searching about. Without it, a Search campaign set to "South Africa" will show ads to every Google user Google classifies as present in or interested in South Africa, a pool that can run to tens of millions of people far beyond any useful commercial radius for most businesses.
Location targeting draws on multiple signals: device GPS data, IP address, Google account settings, and search query content. Because none of these signals is perfectly reliable in isolation, Google's 2026 location targeting documentation acknowledges that 100% accuracy is not guaranteed — a good reason to review the geographic report regularly rather than assume the settings you chose are the ones producing every impression. The minimum targetable radius is 1 km, below which Google may not serve ads at all due to privacy thresholds and minimum user-count requirements.
For the 51.7 million South Africans online (79.6% internet penetration, according to DataReportal's Digital 2026 South Africa report), the overwhelming majority access the internet via mobile — 98.7% of SA mobile connections are mobile broadband. That means location signals from smartphones dominate, and Google's geotargeting is generally more accurate for mobile users than for desktop sessions over shared or VPN connections. A search on a mobile device in Sandton will almost always resolve to Sandton.
Five Targeting Levels for South African Campaigns
Google Ads geotargeting South Africa campaigns can use five distinct geographic granularities, each suited to a different business type. Choosing the wrong level is the most common setup mistake — typically either too broad (province when city would do) or too narrow (a single suburb when the suburb is not individually targetable in Google's system). The table below maps each level to the SA business type it fits.
| Targeting Level | SA Examples | Best For | Watch Out For |
|---|---|---|---|
| Country | South Africa (whole country) | E-commerce shipping nationally; national brand awareness; software/SaaS with no service area | Extremely broad — rural areas with low purchase intent eat budget if no exclusions are set |
| Province/Region | Gauteng, Western Cape, KwaZulu-Natal, Eastern Cape, Limpopo | Regional service businesses (security companies, logistics firms, commercial cleaners covering a whole province) | Gauteng is SA's most populous province and still very broad for most SMEs — layer city bid adjustments on top to concentrate spend in the right metro |
| City/Metro | Johannesburg, Cape Town, Durban, Pretoria, Gqeberha, Bloemfontein | Most local service businesses; retailers with multiple metro-area locations; professional services | Google's "Johannesburg" target includes greater metro, not just the CBD — check geographic report to see actual spread |
| Postal Code | 2196 (Sandton), 8001 (Cape Town CBD), 4051 (Durban CBD) | Businesses with a precise service zone that maps to a postal district; delivery businesses with strict zone rules | SA postal codes can cover large or oddly shaped areas — confirm coverage on a map before relying on this level |
| Radius | 5 km around Rosebank; 15 km around the Umhlanga Ridge; 2 km around a Centurion clinic | Walk-in businesses; tradespeople with a defined service area; any business where drive time matters | Set distance in km, not miles — some account configurations default to miles, turning a 10 km target into a 16 km one |
A practical note on suburbs: many SA suburbs are not individually addressable in Google Ads as named location targets. Google's geo database recognises Johannesburg, Sandton, and Pretoria, but may not surface Parkhurst, Linden, or Houghton as separate selectable targets. If the suburb you need is not appearing in the location search, switch to radius targeting centred on that suburb's main street, or use the postal code if you know it.
Choosing the Right Level
Walk-in business or local tradesperson: start with radius, set in km. Metro service business: target the city, add bid adjustments for your highest-converting suburbs. Provincial or national coverage: start broad, then use location exclusions to cut areas you don't service.
Presence vs. Presence or Interest — the Setting That Leaks Budget
The most consequential setting in Google Ads location targeting is also the least visible: the advanced location option that controls who Google includes in your targeted area. This setting determines whether "target Cape Town" means people physically in Cape Town, or everyone who has expressed digital interest in Cape Town from anywhere in South Africa — or the world.
Google ships every new campaign with "Presence or interest" as the default. This setting reaches users who are likely to be in, regularly present in, or have shown interest in your targeted locations. The interest component is driven by search queries and browsing behaviour: someone in Johannesburg who searches "Cape Town dentist" while planning a holiday qualifies as interested in Cape Town — and your Cape Town dentist campaign will bid for them.
For most SA local service businesses, this is the wrong setting.
| Business Type | Recommended Setting | Why |
|---|---|---|
| Walk-in businesses (salon, clinic, gym, restaurant) | Presence only | Only users physically near you can become customers; interest-based reach is pure waste |
| Local tradespeople (plumber, electrician, painter) | Presence only | You dispatch to a physical address — someone in another province cannot use your service |
| Professional services (accountant, attorney, financial advisor) | Presence only | Most SA clients still want in-person or at least same-city — remote interest rarely converts to retained work |
| Tourism and hospitality (guesthouse, tour operator, hotel) | Presence or interest | The person planning a Cape Town holiday from Johannesburg is exactly who you want to reach before they book |
| Event businesses and destinations | Presence or interest | Advance research from outside the area drives bookings; exclude the interest component and you miss the planning phase |
| National e-commerce (ships anywhere in SA) | Presence or interest | You can fulfil anywhere, so wider reach is a feature, not a bug — but still exclude areas you cannot ship to |
To change this setting: go to your campaign, click Settings → Locations → Location options. The toggle is labelled "People in or who show interest in your targeted locations (recommended)" for Presence or interest, and "People in or regularly in your targeted locations" for Presence. Google marks the first as recommended — which is accurate for travel and e-commerce, and wrong for most local SA service businesses.
Note on exclusions: Location exclusions default to "Presence" — meaning Google will block the exclusion from showing to people physically in the excluded area, but still serve to people interested in it. If you want to fully block an area (say, you service Gauteng but not Soweto for a specific campaign), set the exclusion and verify using the geographic report.
Setting Up Radius Targeting for a South African Business
The radius targeting Google Ads provides anchors your ads to a circular area around a specific address or map point — the most precise native option for businesses where physical proximity to the customer determines whether a lead is useful. Here is the step-by-step for a South African campaign.
- Open your campaign and go to Settings → Locations. Click "Enter another location" to open the location search.
- Type your full street address, suburb, or city. If the suburb does not appear as a selectable target, type the broader city name and proceed to the radius step.
- Click the "Radius" option in the drop-down next to the search result. A distance field and unit selector will appear.
- Set the unit to kilometres. Practitioner experience with SA accounts suggests some configurations may default to miles — a 10-mile radius covers approximately 16 km, which is likely larger than you intend for a suburb-level business. Always confirm the unit before saving.
- Enter your radius distance. As a working starting point: walk-in businesses in a dense suburb (Sandton, Sea Point, Umhlanga Ridge) typically start at 5–8 km; tradespeople covering a larger service area often start at 15–20 km; clinics and professional practices in lower-density areas like Fourways or Tyger Valley may extend to 10–12 km. These are starting heuristics — the geographic report will tell you where your actual conversions cluster within a few weeks.
- Save and switch to "Presence only" in Location options unless your business is a tourism or destination type.
Practical approach: A Bryanston veterinary practice targets a 7 km radius around the clinic in Presence mode. After four weeks, the geographic report reveals that conversions are clustering in a much tighter band around the clinic — the outer ring is generating clicks but no bookings. The practice tightens the radius to match the actual conversion footprint and layers a location bid adjustment on the innermost zone. Budget stays the same; a larger share goes to the users most likely to book.
What to avoid: A Bellville attorney targets all of Western Cape in "Presence or interest" mode. The geographic report shows spend in Mossel Bay, George, and Knysna — all users who searched for Cape Town attorneys while travelling the Garden Route. Realistic conversion rate for those users: very low. Fix: switch to Cape Town city target + Presence only, and exclude the Garden Route districts if needed.
Location Bid Adjustments — Making Geography Work Harder
The location bid adjustments Google Ads provides let you increase or decrease your bid for a specific geographic area within your broader target, without needing to restructure your campaign. The permitted range runs from -90% (bid nearly zeroed out) to +900% (bid multiplied tenfold). The practical use is more modest: a meaningful positive uplift on high-converting suburbs, or a reduction on outlying areas where spend is happening but leads are not.
The arithmetic is straightforward: if your ad group default bid is R8 and you set a +25% adjustment for Sandton, Google bids R10 for a user located in Sandton and R8 for a user in the rest of your Johannesburg target. You stay competitive where it matters most without raising every bid across the board.
To layer bid adjustments: go to Campaigns → Settings → Locations, select the location you have already added, and click the bid adjustment column. Enter the percentage. You can add adjustments at multiple geographic levels — a province-level campaign might set a positive adjustment for Johannesburg city and a separate, lower uplift for Cape Town city within the national target, concentrating budget where commercial density is highest.
When to Use Bid Adjustments
Add bid adjustments after at least three to four weeks of geographic data. Before that, you are adjusting without signal. Pull the geographic report, identify your top two or three converting locations, and apply a modest positive adjustment there before making aggressive changes. Negative adjustments are useful for areas generating clicks but zero conversions over a meaningful period — a sustained pattern, not a single week of noise.

Get a Budget Efficiency ReviewReading the Geographic Report
The geographic report in Google Ads shows you where your ads actually served — by user physical location, not just the location you targeted. It is the primary tool for validating that your google ads geotargeting settings are working as intended, and the first place to look when a campaign's click-to-conversion rate is worse than expected.
Find it under Campaigns → Insights and Reports → Predefined reports → Geographic (the exact path may vary by interface version). The report offers two views: User locations (where the user physically was) and Location of interest (the location referenced in their search query). For a local SA business on Presence only, the two should broadly align. If user locations show impressions far outside your radius, check that your advanced location option was saved correctly — a common oversight after account-level or campaign-level changes.
Actionable steps from the geographic report:
- Sort by cost. Identify the towns, cities, or districts spending budget with zero or near-zero conversions over a 30-day window. These are exclusion candidates.
- Sort by conversion rate. Identify the areas where your cost per conversion is lowest. These are bid-adjustment candidates — add them as named locations within your campaign and apply a positive adjustment.
- Cross-reference with payday timing. SA campaigns can show geographic skews tied to payday cycles — certain suburbs show higher conversion rates in the last week of the month. This is a scheduling and budgeting insight as much as a geographic one.
For guidance on which keywords bring the wrong traffic into those locations, the Google Ads negative keywords guide for South Africa works alongside geotargeting to refine what triggers your ads and where. Location exclusions and negative keywords solve related but different parts of the same problem: where your ads show, and what queries trigger them.
Why South African Businesses Choose Growth Pulse Media for Google Ads
Dirk van Greuning built and scaled a large South African ecommerce business before founding Growth Pulse Media — which means the geotargeting decisions described in this guide are ones he made with real Rand on the line, not theoretical recommendations from an account template. The agency's Google Ads management service covers initial geotargeting setup through to ongoing geographic report review and bid adjustment optimisation.
All campaign work is executed in-house, by senior practitioners who understand the SA market nuances that matter here: the difference in commercial intent between a Sandton search and a Soweto search for the same keyword, the load-shedding effect on search timing in different provinces, and the postal-code quirks that make Cape Town suburb targeting less precise than it looks on the map. Growth Pulse Media works with a limited client load — no account handed to a junior while the senior presents the pitch. Every location setting gets checked at setup and re-checked when the geographic data accumulates enough signal to act on.
Who This Is NOT For
Businesses with no physical service area. If you sell a digital product or service globally and have no reason to restrict where your customers are, location targeting adds complexity with no benefit. A South African software company selling internationally should start broad and use performance data to decide whether to apply positive adjustments by region, not carve up geography before the data exists.
Very early-stage campaigns with under-minimum traffic. Google needs user volume in your targeted area to serve ads reliably. A brand-new local campaign targeting a 1–2 km radius around a business in a low-density suburb may produce erratic serving because the area does not meet Google's minimum user-count thresholds for consistent delivery. Widen the initial target, gather data, then tighten it.
Businesses that rely entirely on Smart campaigns or Performance Max with no manual oversight. Google's automated campaigns have their own location logic and may override or reinterpret your settings. If you are running Performance Max, geotargeting is one of the few levers you retain — but it requires active monitoring. Set-and-forget is not a geotargeting strategy.
Advertisers expecting suburb-level targeting by suburb name alone. Many SA suburbs that feel like distinct places — Parkhurst, Bryanston, Plumstead, Westville — are not individually selectable in Google's location database. If your suburb is not appearing as a target, you need radius targeting, postal code targeting, or a combination. Expecting named-suburb targeting and not finding it is not a Google Ads bug; it is a database gap that radius solves.

Get Your Location Structure ReviewedFrequently Asked Questions
Can I target individual suburbs like Sandton or Umhlanga in Google Ads?
Some SA suburbs do appear as individually selectable location targets in Google Ads — Sandton, for example, is recognisable in Google's geographic database. Others — particularly smaller residential suburbs or newer developments — are not. If the suburb you need does not appear in the location search, use radius targeting anchored to the suburb's main intersection, or target by postal code if the postal district maps to your intended area. The geographic report will show you the actual distribution of impressions regardless of how you set the target.
Should I use "Presence" or "Presence or interest" for a South African local business?
For the overwhelming majority of SA local service businesses — trades, clinics, salons, professional practices, restaurants — use "Presence only." This restricts your ads to users Google believes are physically in or regularly present in your targeted area. "Presence or interest" is the right setting for tourism businesses, event venues, and any business whose customers meaningfully plan and book from outside the service area. Google defaults to "Presence or interest," so switching this manually is a standard first-week optimisation task.
What radius should I start with for Google Ads in South Africa?
There is no universal answer, but a working starting point is 5–8 km for walk-in businesses in dense SA suburbs, 10–15 km for tradespeople or service businesses covering a larger area, and 20–30 km for businesses in lower-density regions like the Winelands or Garden Route where clients travel further. Set the unit to kilometres — some account configurations may default to miles — and treat the first radius as a hypothesis. After three to four weeks, the geographic report will show where your conversions are actually clustering, and you can tighten or widen from there.
Can I exclude specific areas from my Google Ads campaigns?
Yes. Location exclusions work at the same geographic levels as positive targets — country, province, city, postal code, or radius. The exclusion default is "Presence," which blocks the excluded area from users physically there but may still serve to users who searched about it. Apply exclusions to the areas showing consistent spend with no corresponding conversions over a meaningful window — at least 30 days of data, long enough to distinguish a pattern from noise.
How do location bid adjustments work alongside geotargeting?
Location bid adjustments multiply your campaign bid up or down for a specific area within your broader target — the permitted range is -90% to +900%. Apply them after at least three to four weeks of geographic data: identify the areas where your qualified leads cluster in the geographic report, then set a positive adjustment for those locations. According to Google's documentation, the multiplier is applied to the base bid for any user located in that zone — so the platform bids more aggressively in that area without any campaign restructuring required.
