Setting Up Responsive Search Ads That Actually Perform in a Grant Account

Responsive Search Ads (RSAs) are the standard (and only) ad format available in Google Ad Grant accounts. Google retired the older Expanded Text Ad format in 2022, so RSAs are what you're working with.

The concept: you provide up to 15 headlines and 4 descriptions. Google's AI tests different combinations and learns which pairings perform best for different search queries. The more variations you provide, the more combinations Google can test, and the better your results.

The challenge for Grant accounts: every RSA must balance relevance (to maintain Quality Score and CTR compliance) with breadth (enough variations for Google to optimize). This guide shows you how.

Key Takeaways - Fill ALL 15 headline slots and ALL 4 description slots for best results - Mix headline types: keyword-focused, mission, CTA, credibility, location - Pin only when absolutely necessary; excessive pinning limits Google's optimization - Each ad group should have its own RSA tailored to its keyword theme - One RSA can satisfy the "2 ads per ad group" compliance requirement

RSA Basics for Grant Accounts

Each RSA consists of:

• Up to 15 headlines (30 characters each): Google shows 2-3 at a time
• Up to 4 descriptions (90 characters each): Google shows 1-2 at a time
• Final URL: The landing page for this ad
• Display path: Two optional 15-character fields that appear in the URL display

Google dynamically combines your headlines and descriptions to create ads tailored to each search query. From 15 headlines and 4 descriptions, the system can generate thousands of unique combinations.

Compliance Note

Google's account structure requirements state: at least 2 active ads per ad group. However, a single RSA satisfies this requirement because RSAs dynamically generate multiple ad variations. You can have just one RSA per ad group and be compliant.

That said, having 2 RSAs per ad group allows you to test distinctly different messaging approaches (e.g., emotional vs. practical) and see which resonates better.

How to Write Headlines That Drive Clicks

The 5 Headline Types

Fill your 15 headline slots with a mix of these types:

Type 1: Keyword-focused (4-5 headlines) Include the ad group's target keywords directly. These boost ad relevance (a Quality Score factor).

• "Adopt a Rescue Dog Today"
• "Pet Adoption in Portland"
• "Find Your Perfect Rescue Pet"

Type 2: Mission and impact (3-4 headlines) Communicate what your organization does and the difference it makes.

• "Saving Animals Since 2005"
• "10,000 Pets Adopted This Year"
• "Every Animal Deserves a Home"

Type 3: Call-to-action (3-4 headlines) Tell the searcher what to do next.

• "Visit Our Shelter Today"
• "Browse Adoptable Pets Online"
• "Schedule a Meet and Greet"

Type 4: Credibility (2-3 headlines) Build trust with numbers, ratings, or authority signals.

• "Rated 4.9 Stars on Google"
• "Trusted by 5,000 Families"
• "#1 Shelter in [City]"

Type 5: Location or specifics (1-2 headlines) Include geographic or logistical information.

• "Open 7 Days a Week"
• "Free Parking Available"
• "[City]'s Largest No-Kill Shelter"

Headlines That Hurt CTR (Avoid These)

• Generic organizational descriptions: "We Are a Nonprofit Organization"
• Vague value propositions: "Making a Difference"
• Internal jargon: "Our 501(c)(3) Programs"
• Repetitive variations: Don't use 5 headlines that all say the same thing differently

How to Write Descriptions

You have 4 description slots at 90 characters each. Each description should be able to stand alone (Google may show 1 or 2) and complement any headline combination.

Description 1: Mission + specifics "We've helped over 10,000 pets find loving homes since 2005. Browse our adoptable animals online or visit us in [City] today."

Description 2: Services + CTA "From puppies to seniors, all our animals are vaccinated, microchipped, and ready for adoption. Low fees include all vet care. Visit us today."

Description 3: Social proof + emotion "Join thousands of families who found their best friend through [Shelter Name]. Every adoption saves a life. Start your search now."

Description 4: Logistics + CTA "Open 7 days a week with free parking. No appointment needed. Walk in, meet our animals, and take home a new family member today."

Pinning: When to Use It (Sparingly)

Pinning forces a specific headline or description to always appear in a specific position (Headline 1, 2, or 3; Description 1 or 2).

When to pin:

• Your organization name to Headline 1 position (for brand campaigns only)
• A legal disclaimer if required by your industry or country

When NOT to pin:

• Don't pin keywords to positions. Google already prioritizes relevant headlines.
• Don't pin CTAs. Google tests which CTA works best in each position.
• Don't pin more than 2-3 headlines total. Every pin reduces the number of combinations Google can test.

Best practice: If you must pin, pin 2-3 headlines to the same position (e.g., pin three different keyword headlines to Position 1). This gives Google options within the pinned position.

Keyword Insertion

Google Ads supports dynamic keyword insertion, which automatically replaces a placeholder with the keyword that triggered the ad.

Syntax: {KeyWord:Default Text}

Example headline: {KeyWord:Pet Adoption} displays "Pet Adoption" by default, but if the keyword "adopt a rescue dog" triggers the ad, it displays "Adopt A Rescue Dog" instead.

When it works well: In ad groups with tightly themed keywords where any keyword would make a good headline. "Adopt a rescue dog" and "rescue dog adoption" both work as headlines.

When to avoid it: In ad groups where keywords vary significantly in meaning or length. A keyword that's too long gets truncated, and one that's too short looks awkward.

RSA Setup Checklist

Before publishing any RSA:

• All 15 headline slots filled
• All 4 description slots filled
• Keyword from the ad group appears in at least 3-4 headlines
• At least one clear CTA headline (e.g., "Donate Now," "Volunteer Today," "Learn More")
• At least one credibility headline with a number or specific claim
• Descriptions can each stand alone and make sense with any headline combination
• Final URL points to the most relevant page for this ad group's keywords
• No more than 2-3 pins (if any)
• Display path fields filled with relevant terms

Ad Strength Indicator

Google shows an "Ad Strength" rating (Poor, Average, Good, Excellent) when you create RSAs. While not a direct compliance metric, it's a useful guide:

• Excellent: All slots filled, diverse headlines, strong relevance
• Good: Most slots filled, reasonable variety
• Average: Some slots empty, limited variety
• Poor: Too few assets, repetitive headlines, missing descriptions

Aim for "Good" or "Excellent." If your Ad Strength is "Poor," add more headlines, diversify your messaging, and fill all description slots.

Frequently Asked Questions

Does one RSA count as "2 ads" for compliance? Yes. Google has confirmed that a single RSA satisfies the minimum 2 ads per ad group requirement because RSAs dynamically generate multiple ad variations.

How often should I update my RSAs? Review monthly. Check which headlines and descriptions have the most impressions and best CTR (use the "Assets" report). Replace underperforming assets with new variations. Major updates quarterly.

Can I use the same RSA across multiple ad groups? You can, but you shouldn't. Each ad group should have RSAs tailored to its specific keyword theme. Generic RSAs that work across all ad groups are, by definition, not specific enough for any of them.

Do RSAs work the same in every country and language? The format and character limits are the same globally. Write your RSAs in the language your target audience speaks. Character limits apply per character, not per word, so languages with longer words may need more concise messaging.
