Which strategy allows advertisers to adjust bids by geography?

• A. Radius Targeting
• B. Device Targeting
• C. Demographic Targeting
• D. Date Range Targeting

Answer: (A)

Geography-based bid adjustments come from radius targeting. By defining a specific location and a radius around it, you can apply different bid modifiers for users at varying distances from that location, which lets you optimize bids based on how close someone is to a store or point of interest. This is ideal when proximity impacts conversion likelihood or foot traffic, such as bidding higher for people within a 5-mile radius of a shop. The other strategies target non-geographic dimensions: device targeting adjusts by the user’s device type; demographic targeting uses attributes like age or gender; and date range targeting controls when ads run, not where they are. Radius targeting is the clear fit for adjusting bids by geography.
