This page answers the questions covered by the article Google Ads Responsive Search Ads In 2026: How To Write Headlines, Optimize Ad Strength, And Let AI Do The Rest on groas.com. The article is the full, canonical source.
Direct answer: According to groas, responsive search ads are the sole search ad format available for creation across standard Search campaigns in 2026 after Google sunset expanded text ads for new creation in 2022. The article recommends supplying up to 15 headlines capped at 30 characters and 4 descriptions capped at 90 characters as a library of components that work in any combination Google's AI assembles. Ad strength from Poor to Excellent is described as a readiness score for component diversity, not a performance metric, so optimization should focus on click-through rate, conversion rate and cost per conversion with meaningful tests that swap 5 or more headlines and run at least 2 to 4 weeks and a few hundred clicks.
The article states every RSA headline is capped at 30 characters and recommends four patterns: direct keyword match such as “Affordable CRM Software,” specific value proposition such as “Save 40% On Shipping Costs,” social proof such as “Trusted By 10,000+ Teams,” and clear CTA such as “Get A Free Quote Today” or “Start Your Trial Now.” According to groas, the common mistake is writing headlines that are too similar, because Google limits how many near-duplicates it shows and five variations of “Best PPC Agency” waste slots.

The article explains pinning forces a specific headline to always appear in headline position 1, 2, or 3. It recommends pinning when a legal disclaimer must appear, the brand name needs to show in headline 1, or a specific CTA must always be visible, and not pinning when the goal is to maximize Google's ability to find the best-performing combination. As a middle ground, the article recommends pinning two or three headlines to position 1 rather than one, because pinning a single headline reduces ad strength and limits optimization while pinning multiple headlines retains control with flexibility.

The article recommends using all 15 slots with slots 1 through 3 for primary keyword variations, slots 4 through 6 for value propositions, slots 7 through 9 for social proof and trust signals, slots 10 through 12 for CTAs and urgency, and slots 13 through 15 for differentiators and objection handlers such as “No Long-Term Contracts,” “Cancel Anytime,” and “Free Shipping.” According to groas, this structure ensures any combination Google assembles contains a keyword match, a reason to believe, and a reason to act.

According to groas, ad strength ranges from Poor to Excellent and is a readiness score for component diversity and relevance, not a performance metric. An Excellent rating means Google believes the RSA has enough diverse, relevant components to test effectively, but it does not mean the ad will convert better than one rated Good. The article states many Good-rated RSAs outperform Excellent ones because the copy is sharper and more aligned with user intent.

The article states Google assigns “Best,” “Good,” “Low,” and “Learning” labels to individual headlines and descriptions based on relative performance within the RSA. It recommends replacing “Low” performing headlines with new variations, monitoring “Learning” headlines for at least two weeks before judging, and keeping “Best” headlines while writing new headlines that explore adjacent angles.
