Ad Copy Template: Write Headlines and Descriptions That Convert

The difference between a Google Ads campaign that delivers strong returns and one that drains your budget often comes down to the copy. Your ad headlines and descriptions are the first interaction potential customers have with your business, and you have just a few words to convince them to click. A reliable ad copy template gives you a structured starting point that you can adapt for any campaign, product, or audience.

For Singapore businesses competing in tight markets — from property and education to F&B and professional services — well-written ad copy is a competitive advantage. When your competitors are bidding on the same keywords, the quality of your headlines and descriptions determines who earns the click and who gets ignored.

This guide provides ready-to-use ad copy templates for Google Ads, including headline formulas, description frameworks, call-to-action examples, and a structured approach to A/B testing. Whether you manage campaigns in-house or work with our Google Ads team, these templates will help you write copy that converts consistently.

Google Ads Character Limits

Before writing any ad copy, you need to know exactly how much space you have to work with. Google Ads enforces strict character limits, and exceeding them means your copy gets truncated or rejected. Here are the current limits for 2026:

Ad Component	Character Limit	Quantity Allowed
Headline	30 characters	Up to 15 headlines
Penerangan	90 characters	Up to 4 descriptions
Display path	15 characters each	2 paths
Final URL	2,048 characters	1 URL
Callout extension	25 characters	Up to 10
Sitelink title	25 characters	Up to 8
Sitelink description	35 characters per line	2 lines per sitelink
Structured snippet value	25 characters	Up to 10 values

With Responsive Search Ads (RSAs), Google mixes and matches your headlines and descriptions automatically. This means each headline must make sense on its own and in combination with any other headline. Write self-contained headlines that do not depend on appearing alongside a specific partner headline.

Count characters carefully. Use a character counter tool or spreadsheet formula to verify every headline and description before entering it into your campaign. One character over the limit means your copy will not run.

Headline Formulas That Work

Writing headlines within 30 characters is a discipline. Every word must earn its place. Use these proven formulas as starting points, then adapt them with your specific keywords, brand name, and value propositions.

Formula 1: Keyword + Benefit

“SEO Services — Rank Page 1” (27 chars)
“Web Design — Fast & Affordable” (30 chars)
“Accounting — Save 30% on Tax” (28 chars)

Formula 2: Action + Keyword

“Get Expert SEO Services” (24 chars)
“Book Your Free Consultation” (28 chars)
“Grow Your Business Online” (26 chars)

Formula 3: Number + Keyword

“500+ 5-Star Google Reviews” (27 chars)
“15 Years of SEO Experience” (27 chars)
“Prices from $299/Month” (22 chars)

Formula 4: Question Format

“Need More Website Traffic?” (27 chars)
“Looking for a Web Designer?” (28 chars)
“Want More Leads in 2026?” (25 chars)

Formula 5: Location + Service

“SEO Agency in Singapore” (24 chars)
“Singapore Web Design Pros” (26 chars)
“Digital Marketing — SG” (22 chars)

Formula 6: Urgency or Scarcity

“Limited Slots Available” (24 chars)
“Offer Ends This Friday” (23 chars)
“Only 3 Spots Left in March” (27 chars)

For RSAs, provide a mix of headline types. Include at least two keyword-focused headlines, two benefit-focused headlines, one brand headline, and one with a call to action. This gives Google enough variety to find high-performing combinations.

Description Formulas and Frameworks

Descriptions have 90 characters — enough for one or two substantive sentences. Use this space to expand on the promise made in your headline, address a potential objection, or provide specific details that build credibility.

Framework 1: Benefit + Proof + CTA

“Increase your organic traffic by 200%. Trusted by 300+ Singapore businesses. Get a free audit today.” (Note: this would need to be trimmed to fit 90 characters per description line.)

Framework 2: Problem + Solution

“Struggling with low website traffic? Our SEO experts deliver measurable results. Call now.” (90 chars)
“Wasting money on ads that don’t convert? We optimise campaigns for maximum ROI. Learn more.” (90+ — trim as needed)

Framework 3: Feature + Benefit

“Custom web design with SEO built in. Launch a site that ranks and converts. Free quote.” (87 chars)
“Data-driven Google Ads management. Lower your cost per lead and scale profitably. Call us.” (90 chars)

Framework 4: Social Proof + CTA

“Rated 4.9/5 by 400+ clients across Singapore. See why businesses trust us. Get started.” (89 chars)
“Award-winning digital marketing agency in Singapore. Proven results since 2010. Contact us.” (90+ — trim)

Write at least four descriptions for each RSA. Pin your strongest description to position one to ensure it appears most frequently. Test different angles — some descriptions should focus on benefits, others on credibility, and others on urgency.

Call-to-Action Examples

A clear call to action tells the user exactly what to do next. The CTA should match the intent of the keyword and the action available on your landing page. Here are CTAs categorised by intent:

Intent	CTA Examples	Yang terbaik untuk
Lead generation	“Get a Free Quote”, “Book a Consultation”, “Request a Proposal”	Service businesses, B2B
E-commerce	“Shop Now”, “Buy Online”, “Order Today”, “Add to Cart”	Product retailers, online stores
Information	“Learn More”, “See How It Works”, “Read the Guide”	Awareness campaigns, complex products
Urgency	“Claim Your Offer”, “Reserve Your Spot”, “Limited Time Only”	Promotions, events, seasonal sales
Trust-building	“See Our Reviews”, “View Case Studies”, “Compare Plans”	High-consideration purchases
Trial or demo	“Start Free Trial”, “Try It Free”, “Book a Demo”	SaaS, software, subscription services

Match your CTA to the user’s stage in the buyer journey. Someone searching “best SEO agency Singapore” is further along than someone searching “what is SEO.” The first searcher is ready for “Get a Free Quote” while the second needs “Learn More.”

A/B Testing Your Ad Copy

Writing great ad copy is an iterative process. Even experienced copywriters cannot predict with certainty which headlines and descriptions will perform best. Systematic A/B testing removes guesswork and lets data guide your decisions.

Follow this testing framework:

Step 1: Identify what to test. Test one variable at a time. Good variables to test include headline angle (benefit vs. feature), CTA wording, inclusion of numbers or statistics, urgency language, and brand name placement.

Step 2: Create your test variants. For RSAs, Google handles much of the testing automatically by rotating headline and description combinations. However, you can create two RSAs within the same ad group with deliberately different messaging angles to compare approaches.

Step 3: Set success metrics. Define what “winning” means before you start testing. Common metrics include click-through rate (CTR), conversion rate, cost per conversion, and return on ad spend (ROAS). Choose the metric most aligned with your campaign objective.

Step 4: Allow sufficient data. Do not make decisions based on small sample sizes. Each ad variant needs at least 1,000 impressions and ideally 100+ clicks before the results are statistically meaningful. For lower-volume campaigns, you may need to run tests for two to four weeks.

Step 5: Implement and iterate. Pause the losing variant, apply the winning approach, and move on to testing the next variable. Over time, these incremental improvements compound into significantly better campaign performance.

For Singapore-based campaigns with moderate budgets, focus your testing on the elements with the greatest potential impact: headlines (which determine CTR) and landing page alignment (which determines conversion rate). Our team covers both dimensions through integrated Iklan Google and web design services.

Singapore-Specific Ad Copy Tips

Writing ad copy for Singapore audiences requires understanding local nuances that generic templates miss. Here are actionable tips for Singapore campaigns:

Use SGD pricing when relevant: If your ad mentions pricing, use the dollar sign with SGD context. “From $99/mth” is clearer than “From $99/month” when space is limited, and Singapore users assume SGD by default.
Reference local trust signals: Mention Singapore-specific credibility markers like “ACRA registered,” “MAS regulated,” “Trusted by 200+ SG businesses,” or awards from local organisations.
Include location when it matters: For local services, include “Singapore” or specific area references in headlines. Users searching from Singapore respond to local relevance.
Consider bilingual keywords: Depending on your audience, you may want to test ads with Mandarin or Malay keywords for specific segments, though English typically dominates Google search in Singapore.
Align with local events: Reference National Day promotions, GSS (Great Singapore Sale), Chinese New Year offers, or Hari Raya specials when timing aligns with your campaigns.
Respect cultural sensitivity: Singapore’s multicultural audience means your ad copy should be inclusive and avoid assumptions about any single cultural group.
Optimise for mobile: Over 80% of Google searches in Singapore happen on mobile devices. Ensure your headlines make sense in the truncated mobile ad format, where only two headlines may display.

How many headlines should I write for a Responsive Search Ad?

Provide at least eight to ten headlines out of the fifteen available slots. More headlines give Google more combinations to test, improving your chances of finding high-performing pairs. Ensure each headline is distinct — avoid repeating the same message in slightly different words.

Should I include my brand name in ad headlines?

Yes, include your brand name in at least one headline, but do not pin it to position one unless you have strong brand recognition. For most Singapore SMEs, leading with a benefit or keyword performs better than leading with the brand name.

What is a good click-through rate for Google Ads in Singapore?

Average CTRs vary by industry, but a general benchmark for search ads in Singapore is 3% to 6%. Highly targeted campaigns with strong ad copy and keyword alignment can achieve 8% or higher. If your CTR is below 2%, your ad copy likely needs improvement.

How often should I update my ad copy?

Review ad copy performance monthly and refresh underperforming ads quarterly. Even well-performing ads can experience ad fatigue over time. Seasonal changes, new offers, and competitive shifts also warrant copy updates.

Can I use emojis or special characters in Google Ads?

Google Ads generally prohibits emojis and most special characters in ad copy. You can use standard punctuation, ampersands, and percentage signs. Excessive use of capitalisation (all caps) and exclamation marks will also lead to ad disapproval.

What is the difference between ad copy and landing page copy?

Ad copy is the text that appears in the ad itself — headlines, descriptions, and extensions. Landing page copy is the text on the page users arrive at after clicking the ad. Both must be aligned in messaging and offer for optimal conversion rates. Mismatched expectations between ad and landing page are a leading cause of poor campaign performance.
