Keyword match types determine how closely someone's actual search has to match your chosen keyword before your ad is eligible to show. Getting this wrong is one of the most common sources of wasted ad spend in Google Ads.
Exact Match: Precision Over Reach
Exact match shows your ad only for searches that closely match the specific meaning of your keyword. It offers the most control and typically the highest relevance, but also the smallest reach — you'll miss searches you didn't anticipate, even closely related ones.
Broad Match: Reach Over Precision
Broad match lets Google show your ad for a much wider range of related searches, using signals like landing page content and account history to judge relevance. This can surface valuable searches you'd never have thought to add manually — but it can also waste budget on loosely related, lower-intent searches if not carefully monitored.
Where Most Advertisers Get This Wrong
Using broad match without diligent negative keyword management is one of the fastest ways to burn through budget on irrelevant traffic. Using only exact match, on the other hand, can leave an account starved of the volume needed for automated bidding to optimize well.
A Practical Approach
Many accounts benefit from a mix: exact match on proven, high-intent keywords paired with broad match (closely monitored, with strong negative keyword lists) to discover new converting search terms over time.
The Bottom Line
Neither match type is universally better — the right mix depends on how much manual control you want versus how much you're willing to let Google's automated systems explore on your behalf.
