After implementing Smart Bidding and broad match, what are three campaign best practices you should follow?

The selection is correct because using responsive search ads, monitoring Quality Score, and being mindful of negative keyword targeting are the essential pillars for managing the increased reach provided by broad match and Smart Bidding. Since broad match expands your reach to a wider variety of queries, responsive search ads are necessary to automatically assemble the most relevant creative for each unique search, while monitoring Quality Score ensures your ads remain high-quality and competitive in those new auctions. Simultaneously, because broad match interprets intent broadly, being mindful of negative keyword targeting is a critical safeguard to prevent your ads from appearing for irrelevant or low-value searches that do not align with your business goals. Together, these practices allow the AI to explore new opportunities while maintaining the precision and cost-efficiency required for a healthy, high-performing Search campaign.
