Quick answer: Great Google Ads copy matches what the searcher expects to find, makes a specific promise, and gives them a reason to click now rather than later. Generic copy (“Quality Service”, “Experts in Our Field”) kills CTR. Specific, benefit-driven copy (“50+ Sydney Websites Launched in 2025”) wins auctions and attracts the right clicks.
Introduction
A Google Ad gets about 0.5 seconds of attention. You have three headlines of 30 characters each and two descriptions of 90 characters each to convince someone to choose you over the 3-4 other ads on the same page.
Most advertisers waste this space on vague platitudes. “Experienced Professionals.” “Quality You Can Trust.” “Call Us Today.” These headlines say everything and nothing. They don’t give the searcher any specific reason to click.
The ads that win are specific, relevant, and direct.

RSA Structure — What Google Actually Uses
Responsive Search Ads (RSAs) are Google’s current standard ad format. You provide up to 15 headlines and 4 descriptions. Google tests combinations and learns which perform best for each search query and user context.
Key facts about RSAs:
– Google shows 2-3 headlines at a time (you don’t control which, unless you pin)
– Google shows 1-2 descriptions at a time
– You need at least 5 headlines to publish; 12+ for “Excellent” strength
– Duplicate or near-duplicate headlines reduce your strength score
– Each headline must stand alone meaningfully (Google may show only one from your set)
The Headline Hierarchy
Not all 15 headlines are equal. Write them in priority order:
Tier 1 — Must include (highest value):
– Service/Product + Location (if local)
– Your main differentiator (price, speed, quality guarantee)
– Primary CTA
Tier 2 — Should include:
– Social proof (number of clients, years, awards)
– Specific benefit or outcome
– Trust signal (licensed, certified, award-winning)
Tier 3 — Nice to have:
– Promotional offer
– Secondary benefit
– Problem acknowledgment
– Question format (“Looking for Web Design?”)
– Urgency signal
Write at least 2 headlines in each tier. The diversity helps Google find winning combinations.
10 Proven Headline Formulas
Formula 1: [Service] + [Location] + [Qualifier]
“Web Design Sydney CBD” / “Emergency Plumber North Sydney”
Works because it matches the most common search format. High expected CTR.
Formula 2: [Number] + [Proof Unit] + [Timeframe]
“150+ Websites Launched in 2025” / “500 Leads Generated This Year”
Specific numbers are credible. Generic claims (“Hundreds of Clients”) are not.
Formula 3: [Pricing Signal] + [Outcome]
“From $1,499 — Sites That Convert” / “Fixed-Price Packages From $99/mo”
Price signals pre-qualify clicks. If your price is competitive, show it. If not, use “Premium” instead.
Formula 4: [Problem] → [Solution]
“Low Traffic? We Fix That” / “Wasting Budget on Google Ads? Stop.”
Problem-awareness headlines connect emotionally. Works especially well for pain-point-driven searches.
Formula 5: [Speed/Simplicity Promise]
“Live in 14 Days. Zero Jargon.” / “Setup Today. Leads This Week.”
Fast delivery and simplicity are underrated benefits. Buyers are time-poor.
Formula 6: [Guarantee]
“Results in 90 Days or We Work Free” / “7-Day Satisfaction Guarantee”
Guarantees remove purchase risk. Use them if you genuinely offer one — never bluff.
Formula 7: [Social Proof Format]
“Rated 4.9★ by 200+ Clients” / “Google Partner Agency — Verified”
Third-party validation beats self-promotion.
Formula 8: [Exclusive / Scarcity]
“Only 3 Client Spots Available” / “Limited to 10 Projects This Month”
Use carefully and only if true. Scarcity fatigue is real.
Formula 9: [Question That Mirrors Their Thought]
“Need a Web Designer in Sydney?” / “Tired of Leads Who Don’t Convert?”
Questions feel conversational and can increase CTR when they match the searcher’s mental state.
Formula 10: [Feature + Benefit Stack]
“Custom Code. Fast Load. More Leads.” / “SEO-Ready. Mobile-First. Converts.”
Three-point structure packs density into 30 characters. Works when features matter to the searcher.
Writing Descriptions That Convert
Descriptions (90 characters each) are where you elaborate. Most advertisers use generic copy here — wasted opportunity.
Structure a strong description:
– Lead with the primary benefit or outcome
– Add a secondary proof point or feature
– End with a CTA or urgency element
Weak description: “We are a professional web design company with years of experience. Contact us today for a quote.”
Strong description: “Websites built to rank on Google and convert visitors — not just look good. Request your free 45-min strategy call.”
The difference: specificity (“rank on Google and convert”), honesty (“not just look good”), and a specific CTA (“45-min strategy call” vs vague “contact us”).
Description rules:
– Don’t repeat what’s already in the headlines
– Each description should be able to stand alone with any 2 headlines
– Avoid exclamation marks in descriptions (policy violations for excessive punctuation)
– Don’t capitalise words that aren’t proper nouns
Display Paths
The display URL is what users see in the ad — not where they actually land. Format: yourdomain.com/Path1/Path2.
Each path can be up to 15 characters. Use keywords in paths:
– /web-design/sydney (better than /services/contact)
– /google-ads/audit (better than /landing-page-3)
– /plumber/emergency (better than /home)
The display path signals relevance. A searcher looking for “web design sydney” sees /web-design/sydney and immediately knows they’re in the right place.
Ad Copy Testing
For RSAs, use Campaign Experiments in Google Ads to A/B test headline sets. Run tests for at least 2-3 weeks with 100+ impressions each before declaring a winner.
What to test:
– Pricing signals vs no pricing (does showing price improve conversion quality?)
– Guarantee vs social proof (which drives more conversions?)
– Problem-focused vs benefit-focused headlines
– Specific CTA (“Book Free Call”) vs generic (“Get in Touch”)
FAQ
Q: Should I pin headlines in RSAs?
A: Pin sparingly. Pinning removes Google’s ability to test combinations. Only pin a headline to Position 1 if it must always show (e.g., a critical disclaimer or offer). Over-pinning reduces Performance Strength to “Limited.”
Q: How many RSAs should I have per ad group?
A: 2-3 RSAs per ad group. With 2 RSAs, Google can still rotate and learn. Having too many RSAs dilutes data — Google can’t learn which performs best if each ad gets only a handful of impressions.
Q: Can I reuse the same headlines across multiple ad groups?
A: Yes, but differentiate where possible. Ad groups targeting different keywords should have headlines that mention those keywords. Generic headlines that work for any ad group will underperform vs tailored copy.
Q: What’s the “Ad Strength” score and does it affect performance?
A: Ad Strength (Poor → Good → Excellent) measures creative diversity and adherence to RSA best practices. “Excellent” correlates with better performance, but it’s a guideline, not a guarantee. Focus on actual metrics (CTR, CVR, CPA) over strength scores.
Q: My CTR is high but conversion rate is low. Is the ad copy the problem?
A: Not necessarily — but possibly. High CTR with low CVR often means your ad is attracting the wrong kind of click (misleading promise, wrong audience). Check if your ad promises something your landing page doesn’t deliver. Also check if irrelevant searches are triggering clicks (Search Terms report).
Conclusion
Ad copy is where your entire Google Ads strategy becomes visible to the searcher. All the structural work — ad groups, keywords, bidding — exists to get the right person to see your ad. The ad itself determines whether they click.
Write with specificity. Use real numbers. Make a direct promise. And always test. The gap between a good ad and a great ad is often one specific headline that turns a browser into a buyer.
