How To Use Location Targeting In Google Ads Properly

Location targeting in Google Ads is one of those settings that looks straightforward on the surface but can quietly drain your budget if you get it wrong. Many advertisers set a location, tick a box, and assume the work is done. In reality, how you configure location targeting has a direct impact on who actually sees your adverts, how relevant those impressions are, and ultimately, whether your campaigns deliver a return worth talking about. If you want to use location targeting in Google Ads properly, it requires more thought than most people give it.

Understanding How Google Interprets Location

Before you adjust a single setting, it is worth understanding what Google actually does with location data. When someone searches on Google, the platform attempts to determine where that person is, or where they are showing interest in. This is an important distinction. A user based in Manchester could be searching for services in London, and Google may serve your London-targeted advert to them because of that expressed interest.

This is handled through what Google calls location options, specifically the difference between "Presence or interest" and "Presence only". By default, Google sets campaigns to target people who are in your chosen location or who have shown interest in it. For most local businesses, this default is not what you want. If you are a plumber in Birmingham, you do not want your adverts appearing to someone in Edinburgh who once Googled Birmingham city centre hotels. Switching to "Presence" only means your adverts are shown to people who are physically located in your target area, which is almost always the more sensible choice for service-based businesses.

Choosing the Right Location Layers

Google Ads gives you several ways to define a location. You can target entire countries, regions, cities, postcodes, or set a radius around a specific point on a map. Each of these has its place depending on what you are trying to achieve.

For a national e-commerce brand, targeting the United Kingdom as a whole might make complete sense. But for a local restaurant, a dental practice, or a trades business, that level of targeting is far too broad and will result in wasted spend. Using radius targeting, often called proximity targeting, allows you to draw a circle around your premises or service area and only show adverts to people within that zone. This is particularly effective for businesses where physical proximity matters, such as emergency tradespeople, clinics, or hospitality venues.

Postcode targeting is another layer worth considering, especially when you know your best-performing customer areas from your own data. If you have a history of strong conversions from specific postcode districts, you can focus budget there while reducing spend in areas that historically convert less well.

Using Location Bid Adjustments Strategically

One of the most underused features within location targeting is bid adjustments. Rather than simply switching areas on or off, bid adjustments let you increase or decrease how aggressively you bid in specific locations. This gives you a much more nuanced level of control over where your budget goes.

For example, if you operate across a broad region but your strongest customer base consistently comes from one particular city or area, you can apply a positive bid adjustment to that location. This tells Google to compete more aggressively for clicks from users in that zone without abandoning the wider region entirely. Conversely, if certain areas within your targeting produce poor quality traffic or rarely convert, a negative bid adjustment reduces what you are willing to spend there rather than excluding it completely.

To apply these adjustments intelligently, you need data. Spend time in the Location reports section within Google Ads, found under the campaign or ad group level, and analyse performance by location over a meaningful period. Look at cost per conversion, conversion rate, and click-through rate across different areas. The patterns you find here should directly inform your bid adjustment decisions.

Targeting Locations You Do Not Service

This is one of the most common and costly mistakes in location targeting. Businesses often target a city or region because it sounds like a sensible audience, without truly considering whether they can realistically serve customers there. If someone clicks your advert, lands on your site, and then discovers you do not cover their area, that click was wasted money and a poor user experience.

Before setting any location targets, map out your genuine service area honestly. Be specific about where you can and cannot take on work. If your delivery radius only extends to 30 miles from your depot, there is no commercial sense in targeting postcodes 60 miles away. Tightening your location targeting to reflect your actual service capability will almost always improve your campaign efficiency.

Excluding Locations Correctly

Location exclusions are just as important as the locations you choose to target. Within any campaign, you can add locations as negative targets, which prevents your adverts from showing to people in those areas. This is particularly useful when you are targeting a broad region but need to carve out specific towns, cities, or postcodes that fall outside your service area or have historically shown poor performance.

If you are targeting a county-wide area but one particular town regularly produces irrelevant clicks or zero conversions, excluding it is a straightforward way to stop spending money there. It is a simple action but one that many advertisers overlook, leaving budget to leak into areas that serve no useful purpose for the campaign.

Location Targeting for Multi-Location Businesses

If you operate from multiple locations or service areas, the way you structure your campaigns becomes especially important. Rather than lumping all locations into a single campaign, consider building separate campaigns or ad groups for each key area. This allows you to tailor ad copy to local audiences, apply location-specific bid adjustments, and analyse performance cleanly without one area masking the performance of another.

A business with premises in three cities, for instance, can create three separate campaigns with location-specific headlines referencing each city. This level of relevance tends to improve quality scores and click-through rates, because the advert speaks directly to the person's location rather than relying on generic messaging. Google Ads supports location insertion in ad copy, which can further automate this localisation at scale.

Reviewing Location Data Regularly

Location targeting is not a set-and-forget element of campaign management. Consumer behaviour shifts, business circumstances change, and the data you accumulate over time will reveal patterns that are worth acting on. Make location performance analysis a regular part of your campaign review process, not something you glance at once and move on from.

Look at performance trends by location across different time periods. Seasonal shifts can affect which areas perform best. A coastal area might perform well in summer and poorly in winter. A commuter town might show stronger performance on weekday mornings. The more granular your analysis, the more precisely you can allocate budget to the areas that genuinely drive results for your business.

Getting Location Targeting Right

Location targeting in Google Ads is not complicated in principle, but it does require deliberate attention. Choosing the right targeting method, setting the correct presence options, applying thoughtful bid adjustments, excluding irrelevant areas, and reviewing performance regularly are the foundations of a well-managed location strategy. These are not advanced tactics reserved for large agencies or enterprise budgets. They are the fundamentals that any advertiser should be applying from day one. Get them right, and your campaigns will work harder, reach more relevant audiences, and deliver far better value for every pound you spend.
