Which match type should I start with?

Exact match on your proven money terms for control, plus one broad-match campaign under Smart Bidding with solid negatives for discovery. Phrase match covers the middle. Let the search terms report, not theory, decide how the mix evolves.

Why is broad match showing my ads for weird searches?

Broad match trusts the bidding system to judge relevance from signals beyond the words, and without conversion data or negatives it explores loosely. Tighten with negatives weekly, and if the account lacks conversion volume, keep broad match on a short budget leash.

Match Types

Match types are settings in Google Ads that control how closely a search must match your keyword for your ad to show, ranging from broad to phrase to exact.

Broader types reach more searches but risk irrelevance, while exact match is tightly controlled. For example, exact match for "seo audit" shows only for very close variants, while broad match shows for loosely related queries. Choosing the right mix balances reach and precision.

Match type choice is really a division of labour with the bidding system. Exact match is control: you decide the queries, predictable but capped. Broad match is delegation: the system explores related queries, and with smart bidding plus honest conversion data, exploration is disciplined by outcomes; without them it is spend leakage at scale. The modern failure is running broad match the old way, manual bids, thin negatives, then blaming the match type for the waste. Whatever the mix, the search-terms report stays the arbiter of whether the theory matches the queries.

Example

One keyword three ways. Exact [seo audit] catches that phrase and close variants: 90 impressions a day, 7% CTR. Phrase "seo audit" adds longer queries containing it: 300 impressions, 4%. Broad seo audit reaches related searches like "check website health": 1,900 impressions, 1.2%, plus discoveries the other types never see. The account uses all three: exact for control, broad with smart bidding for reach.
