What's a benefit of using Smart Bidding with broad match?

The selection is correct because combining broad match with Smart Bidding creates a powerful synergy where the wide reach of broad keywords is precisely tempered by the real-time decision-making of AI. While broad match identifies a vast range of potential search queries related to your business, it is the Smart Bidding component that evaluates the unique contextual signals present at auction time—such as a user's location, device, time of day, and past browsing intent—to determine the likelihood of a conversion. This ensures that the system is not simply bidding on every related term, but is instead picking up on these signals to make sure you’re only competing in the right auctions, at the right bid, for the right user. This automated filtering process allows advertisers to discover new, high-performing search terms that they might have missed with restrictive match types, while maintaining efficiency by avoiding low-potential traffic that does not align with their specific performance goals.
