Note: Smart Bidding Exploration is available only for Search campaigns that use Target ROAS bid strategy.
Smart Bidding Exploration is a new opt-in feature that uses Google’s AI to bid on potentially high-performing search queries. Google AI and flexible ROAS targets work hand-in-hand to fuel an advanced algorithm that captures new searches and secures additional conversions from the traffic you’re already eligible for. The result is scaled performance and traffic diversity, meaning your impressions, clicks and conversions will be driven by more unique search term categories.
Benefits
- A Search category refers to a unique subset of queries grouped together based on user intent, with meaningful differentiation, compared to raw queries which would include incorrect spellings, plurals, and other variations.
- Traffic diversity should be the key metric to evaluate success for this beta feature.
- You might already know about Search categories from the "Insights" page in Google Ads. Learn more About search terms insights .
When to use Smart Bidding Exploration
Example:
A mortgage lender already bids successfully on high-performing, reliable queries like "mortgage" or "home loan” when advertising on Search. Google's systems know these queries will generally help them achieve their ROAS targets. It’s possible that the lender may be missing out on other leads.
