• Phrase match
• Exact match
• Negative match
• Broad match

The correct answer is: Broad match

Explanation: Broad match is the default match type given to all keywords in Google Ads due to its comprehensive nature. As it’s the most inclusive of all match types, you don’t need to assign any other match type, such as exact match, phrase match, or a negative match type. To utilize broad match, you just need to enter the keyword without any additional syntax.
