Google Ads match types

Match types tell Google how closely a search must match your keyword for your ad to show. Broad is the widest; exact is the narrowest. Picking wrong either starves you of volume or wastes spend on irrelevant clicks.

The match types

Exact match

Search must match your keyword or a close variant. Most control, least volume.

Keyword: [red running shoes] → matches "red running shoes", "running shoes red", similar intent.

Phrase match

Search must include your phrase (or close variant) as a subset. Medium control.

Keyword: "red running shoes" → matches "buy red running shoes", "red running shoes for marathon", phrase in there.

Broad match

Search includes anything Google thinks is related. Widest reach, least control. Modern broad match uses AI to find related intent.

Keyword: red running shoes → matches "running gear", "jogging footwear", "athletic shoes red", loosely related.

When to use each

• Exact: tightly-proven high-intent keywords. Scales slowly but predictably.
• Phrase: extended reach with some control. Often the sweet spot.
• Broad: exploration; finding new queries. Always pair with smart bidding (Target CPA or ROAS), without it, broad is chaos.

The modern recommendation

Google has nudged advertisers toward broad match + smart bidding. Works when:

• Your conversion tracking is solid
• You have enough conversion volume for the algorithm to optimize
• You have negative keywords in place

Without those, broad match burns budget.

Negative keywords with broad

Broad match discovers irrelevant queries constantly. Weekly: review the search terms report, add negatives for queries that don't fit.

The hybrid approach

Run exact match for your proven high-ROI keywords (tight control) + broad match with smart bidding for discovery (find new queries). Exact match gets priority when both could trigger.

What to do with this

• Run exact match for proven high-ROI terms (tight control), broad match + smart bidding for discovery (find new queries the algorithm finds profitable)
• Never run broad match without active negative-keyword management, weekly search terms review is the price of broad's discovery upside
• Match the bid strategy to the match type, smart bidding compensates for broad's noise, manual doesn't, the combination matters
• Structure ad groups by match type + theme so your exact terms don't compete with your own broad terms in the auction
• When broad produces a winning query, promote it to phrase or exact in a separate ad group, that locks in the win at tighter control
