Match Types and Negatives: Steering Broad Without Bleeding

Match type debates usually get framed as control versus reach. That framing is a decade out of date. Modern matching is semantic, exact is no longer literal, and broad match behaves less like a wildcard and more like a recommendation engine that reads your conversion data. The practical question is not which match type is safest, but whether your account has the signal quality to steer a loose one.

What each type is for

Broad match has a precondition

Broad match with manual bidding and weak conversion tracking is how accounts burn money on irrelevant queries. Broad match with clean conversion data and a value-based target is how accounts find demand no keyword researcher would have listed. The difference is entirely in the signal, not the match type.

Give the system a loose target and a clear objective, or a tight target and a vague objective - never both loose.

The weekly search terms ritual

Set aside thirty minutes a week. Sort the search terms report by cost, read the top hundred, and sort each into three buckets: irrelevant becomes a negative, relevant but off-theme becomes a candidate for its own ad group, and relevant and converting stays. This single habit does more for account efficiency than most structural rebuilds.

Accounts that skip search term review for a quarter typically find 10-20% of spend on queries nobody would have approved.

Negative lists as shared infrastructure

Negatives added campaign by campaign drift out of sync. Maintain shared lists instead: a universal list for things you never sell, a competitor list, a jobs and careers list, a free-and-cheap list for products with no free tier. Apply them at account level and add to them centrally, so a lesson learned in one campaign protects every other.

Keep brand separate

Brand queries convert cheaply because the person already decided. Mixed into the same campaign as non-brand, they drag the blended cost per acquisition down and hide whether prospecting is working at all. Isolate brand, report it separately, and judge non-brand on its own numbers - that is the only view that tells you whether paid search is growing the business or billing you for demand you already had.
