What are the character limits for Google Responsive Search Ads (RSAs)?

Google Responsive Search Ads allow up to 15 headlines with a maximum of 30 characters each, and up to 4 descriptions with a maximum of 90 characters each. Display paths allow 2 sub-paths of up to 15 characters each.

How many headlines and descriptions are required in a Google RSA?

Google Ads requires a minimum of 3 headlines and 2 descriptions. However, providing all 15 headlines and 4 descriptions significantly improves Ad Strength and impression share.

Does pinning headlines hurt Google Ad Strength?

Pinning reduces Google's machine learning flexibility to test headline combinations. If you must pin for brand or compliance requirements, pin 2 to 3 varied headlines to the same position to preserve algorithmic testing.

FREQUENTLY ASKED QUESTIONS

Google Responsive Search Ads Best Practices

Headlines

How to maximize headline quality?

Include your top keyword in at least 2–3 headlines. Add 2–3 headlines highlighting unique selling propositions (e.g. Free Shipping, Private In-Browser), and 2 headlines with clear calls to action.

Pinning

Does pinning hurt ad performance?

Pinning to Position 1, 2, or 3 forces Google to only show that headline in that slot, limiting algorithm combinations. If you pin, pin 2 or 3 distinct variations to the same position.

Display Paths

Do display paths need to match the landing page?

No. The display path is cosmetic and gives searchers a clear idea of where the ad leads (e.g., example.com/tools/free-trial). The final URL determines the actual destination.

Ad Strength

What makes an ad 'Excellent'?

Providing at least 10 headlines with varied lengths (some short 15-char, some full 30-char), distinct benefits, and minimal redundant keywords.
