Responsive Search Ads: Write Google Ad Copy That Books More Jobs

Responsive Search Ads replaced expanded text ads in Google Ads in 2022. Instead of writing one fixed ad, you supply up to 15 headlines and 4 descriptions, and Google tests combinations automatically to find what converts best for each search. Most contractors set them up once, hit save, and forget them. The result is an ad rated “Poor” or “Average” by Google’s Ad Strength score, which earns fewer impressions and costs more per click than an ad rated “Good” or “Excellent.”

The performance gap is measurable. Ads with an Excellent Ad Strength score achieve a click-through rate of around 7.2%, compared to 2.1% for ads rated Poor. Improving from Poor to Excellent yields roughly 15% more clicks and conversions at the same budget, according to Google’s own benchmarks. A contractor spending $2,000 per month on search ads and running Poor-rated RSAs is effectively giving $300 worth of clicks to competitors every month. The fix costs nothing: it is rewriting the ad.

What Google Does With Your Headlines

Each RSA gives you 15 headline slots (30 characters each) and 4 description slots (90 characters each). Google tests combinations automatically and allocates more impressions to the pairings that drive the most clicks. You do not control which headlines appear together: Google makes that call based on the searcher’s query and your historical performance data.

Most contractors fill in three to five headlines and leave the rest blank. Google then has almost no variation to test, serves the same combinations repeatedly, learns little, and your Ad Strength stays Poor. The more unique headlines you supply, and the more distinct they are from each other, the more material Google has to optimize. Filling all 15 slots with varied, specific headlines is the single highest-impact change most contractor ad accounts can make without spending another dollar.

The Four Headline Categories to Fill

For home service contractors, organize your 15 headlines across four categories. Aim for three to four headlines in each:

Service plus location. This is the most important category. Include the specific service and your primary city or service area in each headline. Google uses these to match your ad to local searches with geographic intent.

• AC Repair in Columbus OH
• Emergency Plumber Columbus Ohio
• Roofing Contractors Columbus Ohio
• HVAC Service Columbus and Suburbs

Differentiator. What separates you from the three other contractors appearing on the same page. Be specific. A claim like “Quality Work” is meaningless. A claim like “NATE-Certified Technicians” or “Family Owned Since 1987” is specific and verifiable.

• Licensed and Insured Since 1987
• NATE-Certified HVAC Technicians
• No-Trip-Charge Guarantee
• Upfront Pricing, No Surprises

Urgency and availability. Home service searches often happen in moments of stress. A homeowner whose furnace stopped working at 8pm is not researching options. They want someone who can come now. Headlines that communicate speed and availability convert at higher rates for emergency and same-day services.

• Same-Day Appointments Available
• 24/7 Emergency Service
• Call Now: We Answer Live
• Appointments as Early as Today

Social proof. Reviews, ratings, and tenure give hesitant homeowners a reason to click over an unfamiliar competitor.

• 500+ Five-Star Google Reviews
• BBB A+ Accredited Contractor
• Serving Columbus for 25 Years

Write 15 unique headlines across these four categories. Never repeat the same word or claim in two separate headlines. Repetition wastes slots and confuses the algorithm.

How to Write Descriptions That Work

Google shows two descriptions simultaneously, selected from your four description slots. Write all four. Each description should be a complete sentence that makes sense regardless of which headlines appear above it: the algorithm may pair any description with any headline combination.

The formula that works for contractors: state the service type, geographic coverage, one credential, and a clear next step. Example: “We repair and replace HVAC systems throughout Columbus and surrounding counties. Licensed, insured, upfront pricing. Call for a free same-day estimate.” That description works alongside any of your headlines and tells the homeowner exactly what to do next.

Avoid descriptions that could apply to any business in any industry: “We provide excellent service to all our customers.” These are skipped over by homeowners scanning results and treated as low-signal by Google’s relevance algorithm. Specific beats vague in every slot.

Pinning: Use It Sparingly or Not at All

Google’s pinning feature locks a specific headline to position 1, 2, or 3 in every ad combination. Many advertisers pin their brand name or primary keyword to position 1 so it always appears first. The tradeoff is significant: every pinned position reduces the number of combinations Google can test, which directly lowers your Ad Strength and your impression volume.

For most contractors, letting Google freely test all 15 headlines produces better results than locking any of them. If you must pin, pin only one headline to position 1 for a legal or compliance reason, and leave positions 2 and 3 unpinned. Pinning every position converts an RSA into a static ad and eliminates the entire value of the format.

Ad Strength: Check It on Every Active Ad

Google rates each RSA as Poor, Average, Good, or Excellent. The rating appears in the Ads column of any campaign view. A Poor rating typically means fewer than five unique headlines, repeated phrases across headlines, or description slots left blank. An Excellent rating requires 15 unique headlines across multiple themes, four complete descriptions, and no repeated phrases.

Check every active RSA in your account today. Open each ad and look for the Ad Strength label in the top right corner of the editor. Any ad rated Poor or Average is underperforming. The path to Excellent is mechanical: add headlines until all 15 slots are filled, eliminate repeated words and phrases, and fill all four description slots with specific sentences.

Match the Landing Page to the Ad

A well-written RSA loses value the moment someone clicks through to a generic homepage. If your headline says “AC Repair in Columbus OH” and the landing page opens to a banner that reads “Full-Service Home Contractor Since 1987,” the homeowner has to do additional work to confirm they reached the right place. Many do not bother and leave.

Each service category in your Google Ads campaign should link to the specific service page that matches the search intent. AC repair ads go to your AC repair page. Emergency plumbing ads go to a page with your emergency phone number in the first visible section. If you are running a single ad group for all your services and sending traffic to your homepage, your conversion rate is lower than it should be regardless of how well-written the ads are.

Three Actions for This Week

1. Open Google Ads and check Ad Strength on every active RSA. Navigate to the Campaigns menu, click into each ad group, and view the Ad Strength rating for each ad. Write down every ad rated Poor or Average. These are where your performance losses are concentrated. A contractor with three ad groups each running a Poor-rated RSA is losing 30 to 50 percent of potential clicks compared to the same spend with Excellent-rated ads.
2. Rebuild each Poor or Average RSA using the four-category headline framework. Open the ad editor and add headlines until all 15 slots are filled. Use the four categories: service plus location, differentiator, urgency and availability, and social proof. Write three to four headlines per category and verify that no two headlines share the same opening word or core claim. Fill all four description slots with specific, complete sentences that work independently of the headlines. Save and let Google begin testing within 24 to 48 hours.
3. Audit the Final URL for each ad group. If any ad group sends traffic to your homepage, update the Final URL to the service-specific page that matches the ad keywords. For an ad group targeting AC repair, the URL should point to your AC repair service page. This single change improves conversion rate for every click those ads generate, because a page that immediately confirms the specific service the homeowner searched for converts at two to three times the rate of a generic homepage.

RSAs do not require a bigger budget. They require better inputs. Most contractor Google Ads accounts are running four or five headlines per ad group and leaving the rest of the platform’s optimization capability unused. An afternoon of headline writing turns Poor-rated ads into Excellent-rated ads and puts 15 to 30 percent more leads through the same monthly spend. The contractors at the top of your local search results are almost certainly running fully built RSAs. The gap between their ad quality and yours is fixable this week.
