To compete in the right auctions with the most data and flexibility, what keyword match type does Smart Bidding need?

Smart Bidding algorithms perform best with broad match keywords because they provide the most data and flexibility. Broad match allows Google Ads to show your ads for a wider range of relevant searches, including misspellings, synonyms, and related queries. This expanded reach gives Smart Bidding more auction opportunities to learn from and optimize bids for conversions. Exact match and phrase match are more restrictive, limiting the search queries that can trigger your ads and thus providing less data for optimization. Negative match prevents your ads from showing for specific irrelevant terms, which is important for refining targeting but doesn't contribute to data volume for Smart Bidding in the same way broad match does.
