On a crowded Google results page, your ad has one job: sound more useful than the nine other blue links around it. That’s not about shouting louder; it’s about speaking directly to what the searcher is trying to solve.
Most Google ads are written by people who know what they want to say. The best Google ads are written by people who know what the searcher needs to hear.
That’s a different exercise entirely — and it produces dramatically different results.
Headlines: Matching Search Intent In 30 Characters Or Less
You have 15 headline slots and 30 characters each. Google tests combinations to find what works. Your job is to give it strong options across three categories:
Intent-Match Headlines — Mirror the search term. ‘Sydney Plumber — Book Today’. ‘Melbourne Dental Clinic Open Now’.
Proof Headlines — Social proof in 30 characters. ‘500+ 5-Star Reviews’. ‘Licensed & Insured Tradies’. ‘Award-Winning Service’.
Action Headlines — What you want them to do. ‘Call For A Free Quote’. ‘Book Your Consult Today’. ‘Get A Same-Day Response’.
Pin your most important headline (usually the intent-match or USP) to position 1. Let Google test the rest. The data will tell you what resonates.
Descriptions That Earn The Click (Without Hype)
Descriptions give you 90 characters × 4 slots. Most advertisers use one or two. Write all four — Google will rotate and you’ll learn which messaging converts.
What earns a click in a service business description:
- Specificity: ‘licensed gas fitter with 15 years in Sydney plumbing’ beats ‘experienced professional’
- Reassurance: remove the perceived risk of the next step (‘free consult, no obligation’)
- Urgency that’s true: ‘next available appointment is Thursday’ beats ‘limited spots available’
- Local proof: ‘trusted by homeowners across [City] since [Year]’
What kills a description:
- Generic adjectives: ‘quality’, ‘professional’, ‘reliable’, ‘affordable’
- Superlatives: ‘the best’, ‘number one’, ‘#1 rated’
- Passive voice: ‘solutions are provided’ — write actively
Test a description that talks about your customer’s problem. Then test one that talks about your solution. The winner isn’t always what you’d expect.
Using Sitelinks, Callouts And Structured Snippets
These ad extensions (now called ‘Assets’) are often the difference between an ad that fills a small space and one that dominates the search results page.
Sitelinks — Additional links below your ad. Use them to direct people to specific service pages: ‘Emergency Callouts’, ‘Get A Quote’, ‘Our Reviews’, ‘Service Areas’.
Callout Assets — Short benefit phrases (25 characters). ‘No Hidden Fees’. ‘Same-Day Service’. ‘Fixed Price Quotes’. ‘Free Consultation’.
Structured Snippets — Lists of services or types. Under ‘Services’: ‘Leak Detection, Hot Water, Blocked Drains, Gas Fitting, Emergency Plumbing’.
Ads with all extensions enabled take up significantly more screen real estate — particularly on mobile, where above-the-fold space is limited. More space = more visibility = more clicks.
Location And Call Extensions For Local Lead Gen
For any service business that operates in a physical location or serves a specific geography, these two assets are non-negotiable:
Location Assets — Links your Google Business Profile to your ad. Shows your address, suburb, and map integration. Builds local trust instantly.
Call Assets — Adds your phone number directly to the ad. On mobile, it becomes a tap-to-call button. For businesses where phone calls are the primary lead source, this is one of the highest-impact additions you can make.
Track call conversions. Set a minimum duration (60 seconds) for a call to count. This data feeds directly into your campaign optimisation.
A/B Testing: How To Continuously Improve Your Ads
The best Google Ads accounts are never ‘done.’ They’re constantly testing.
A simple testing framework:
- Change one element at a time (headline theme, description angle, CTA)
- Let tests run until you have statistical significance — at minimum 100 clicks per variant
- Declare a winner and make the new control
- Immediately start the next test
Within 6 months of consistent testing, your ad creative will be dramatically different from where it started — and dramatically better.
Most agencies don’t test because testing takes time and discipline. It’s one of the clearest differentiators between agencies that drive results and those that maintain the status quo.
Frequently Asked Questions
Q: How many headlines should I write for a Responsive Search Ad?
Write all 15. The more variants you provide, the more combinations Google can test, and the better data you’ll collect on what resonates. Treat each headline slot as an independent test — don’t assume you know which combination will perform best.
Q: Should I pin headlines in my Responsive Search Ads?
Pin sparingly. Pinning a headline to a position (1, 2, or 3) reduces Google’s ability to test combinations. Pin only when a specific message absolutely must appear — such as a legally required disclosure or a core USP that defines your positioning. Everything else is better left for Google to test.
Q: How do I know if my ad copy is performing well?
Look at CTR (click-through rate) relative to industry benchmarks. For service businesses, a CTR above 5% on Brand campaigns and above 3% on non-brand campaigns is generally strong. Below 2% usually signals a mismatch between your ad and the search intent. Also check conversion rate — high CTR with low conversion rate means the ad is promising something the landing page doesn’t deliver.
Q: Should I use different ad copy for different keywords?
Yes. Create separate ad groups for distinct service categories, each with its own tailored ad copy. A plumber shouldn’t use the same ad for ‘blocked drain’ and ‘hot water system installation’ — the intent, urgency, and customer situation are completely different.
Q: How often should I update my ad copy?
Review ad performance monthly. Test a new creative variant every 30–60 days. Update seasonal messaging as needed (summer specials, end-of-year offers). Never set and forget — your competitors are testing, and they’ll outperform you if you don’t.
