Responsive Search Ads
RSA (Responsive Search Ads)
The standard Google Ads text ad format accepting up to 15 headlines and 4 description lines. Google's machine learning tests combinations and learns which pairings perform best for different queries, audiences, and devices. Providing at least 8–10 distinct, non-repetitive headlines maximises the system's ability to optimise.
How Responsive Search Ads works in practice
RSAs replaced the legacy Expanded Text Ad format as the default in June 2022. The system uses machine learning to identify which of the 15 headline and 4 description combinations generate the best CTR and conversion rate for each query-audience-device combination, effectively running hundreds of A/B tests simultaneously. "Ad strength" (Poor, Average, Good, Excellent) measures creative diversity — but it is a proxy for variety, not actual performance; an Excellent-rated RSA can underperform a Poor-rated one with more specific messaging. Pinning specific headlines to specific positions (Pin Headline 1) reduces Google's ability to optimise but is useful when brand messaging or compliance requirements demand fixed placement.
