Exact match means your ad only shows when someone searches for that specific term, while phrase match allows some extra words around your keyword. Marketers use exact match when they know precisely what their buyers search for and want tight control over spending. Phrase match is useful when you want to reach a slightly broader audience without going too wide. Most campaigns use a mix of both, depending on how much data they already have. So what do you think, is there a clear rule for choosing between exact match and phrase match?
