If you bid the same keyword across different campaigns in the same account, what happens?

• A. They will compete against each other
• B. They will not compete against each other
• C. They will be disqualified
• D. They will appear twice

Answer: (B)

Bidding the same keyword in multiple campaigns is treated as writing separate bids in separate bidding contexts. Each campaign has its own budget, bid settings, and targeting goals, so impressions for that keyword are allocated within the campaign rather than across campaigns. Because of this separation, the campaigns don’t directly bid against one another in a single shared auction. If an impression could come from more than one campaign, the platform chooses the winning ad based on the campaign’s bid and relevance signals, but it doesn’t mean the campaigns are fighting each other in one inter-campaign auction. This is why using the same keyword across campaigns won’t cause cross-campaign competition.
