About keyword match types - Google Ads Help
Keywords are words or phrases used to match your ads with what people are searching for.
By using signals that are not available with other match types, broad match is thought to be more likely to display ads that are more suited to the user's intent and situation.

Use with Smart Bidding
It is recommended that you use broad match in conjunction with conversion-focused Smart Bidding .
Smart Bidding
Machine learning can optimize bids for each auction with an emphasis on conversion numbers and conversion values.
Only highly relevant search terms are eligible for bidding, making it easier to achieve high relevance even with partial matches.
Combined with these characteristics, we believe that expansion in directions that are likely to lead to poorer results will be limited, increasing the likelihood of performance improvement.
