Geo-targeting in Google Ads - getting location right for every campaign type
Most advertisers set geo-targeting once at campaign setup and never revisit it. That single decision shapes where your entire budget goes. Done incorrectly, it generates impressive-looking click volumes from locations that will never convert into customers.
Geo-targeting determines which users see your ads based on their physical location or the location they have searched for. The distinction between these two modes matters more than most guides acknowledge. "People in or regularly in my targeted location" and "people searching for my targeted location" are different audiences that require different targeting decisions depending on your business type.
Presence vs interest targeting
Google Ads offers three geographic targeting options: people in your targeted locations, people searching for your targeted locations, or both. For local service businesses - a plumber, a solicitor, a restaurant - you want people physically present in your service area. Select "people in your targeted locations" only. If you also include people searching for your location, you capture users physically elsewhere who are researching your area - useful for tourism businesses, not useful for a local service provider who can only serve people actually within their coverage radius.
For ecommerce businesses that ship nationally or internationally, the interest targeting is often appropriate alongside presence targeting - someone searching for "London-based wine merchant" from Manchester may be a legitimate customer who wants to order delivery.
Location bid adjustments
Within your targeted area, conversion rates vary by sub-region. A solicitor in central Manchester may find that traffic from certain postcodes converts significantly better than others - perhaps because those areas have higher concentrations of business owners who are their target client type. Reviewing conversion data by location at city, region, and postcode level reveals these patterns. Applying positive bid adjustments to high-converting areas and negative adjustments to low-converting ones improves overall campaign efficiency without reducing reach.
Location exclusions
Excluding locations is as important as targeting them. If you do not serve certain areas - whether geographic constraints for local services or competitive reasons for specialist offerings - exclude those areas explicitly. Relying on your targeting radius alone is not sufficient when Google's location interpretation can extend beyond your defined radius for users whose location signals are ambiguous. Explicit exclusions provide a hard boundary that targeting radius does not.
The radius targeting trap
Radius targeting - targeting users within X miles of a specific point - sounds precise but relies on Google's determination of user location, which is not always accurate. A user whose device reports a location at the edge of your radius may or may not actually be within your service area. For businesses with strict geographic boundaries, combining radius targeting with postcode list targeting provides better control than radius alone.
