These three match types control how closely a search has to match your keyword before your ad shows. Broad match is the loosest, meaning your ad can show for searches that are only loosely related to your keyword. Phrase match is more controlled, and exact match means the search has to be very close to what you typed. Beginners often start with exact and phrase match to keep control over who sees their ads, then expand once they have data. Broad match can waste budget fast if you are not watching it closely.
