What are three signals that broad match uses to match search ads with queries?

Broad match in Google Ads leverages several signals to connect user queries with relevant ads, even if the exact keywords aren't present. Smart Bidding is a crucial signal because it helps broad match understand the value of different conversions, optimizing which queries to match based on the likelihood of a desired outcome. Language is essential as it ensures ads are shown to users searching in the correct language, improving relevance. Geographic location is another key signal, allowing broad match to prioritize queries from specific regions, which is vital for local businesses or region-specific campaigns. Device (e.g., mobile, desktop) and Interests are not primary signals broad match uses for query matching itself, though they influence other aspects of ad serving and targeting.
