Google Ads geotargeting allows search advertisers to specify a location, or a set of locations, as the only area(s) in which they want their ads to show. This is an essential tactic for businesses that depend on foot traffic and/or home deliveries, such as restaurants, brick-and-mortar stores, and ecommerce sites.
Why? Because showing ads to consumers outside of the relevant area(s) drives wasted impressions and clicks, thus cutting into a business’ marketing budget without offering any kind of return. So, for a lot of advertisers, geo-targeting is key to an efficient use of marketing funds.
