How to Write Google Ads Copy That Converts
Jakub Nikodym · July 13, 2026

If your Google Ads aren't converting, your ad copy is likely the culprit. Refining your ad text can increase engagement and drive conversions, essential for small businesses looking to maximize limited budgets.
Key takeaways
- Use Responsive Search Ads to find the best-performing copy variations.
- Headline space is limited; focus on the most important messages.
- Call to Action (CTA) is crucial for guiding user actions.
- Use Negative Keywords to optimize the audience targeting.
What should I focus on in my Google Ads headlines?
Your headline is the first thing users see in your Google Ads, making it crucial for grabbing attention immediately. Google allows for 15 headlines, each up to 30 characters in Responsive Search Ads (RSAs). Here's a formula that works:
- Value Proposition: Open with what makes your service stand out. Consider, “24/7 Emergency Plumber” or "Free Quote Within 24 Hours."
- Target Keywords: Incorporate keywords for relevance. Use "Affordable Plumber Near You" or "Experienced Springfield Plumbers." This ensures your ad ranks better and resonates with the search intent.
- Call to Action (CTA): End with action-oriented language like "Book Now" or "Get a Free Quote!"
For instance, if you're a local bakery, you might structure your headlines as follows:
- "Order Freshly Baked Bread"
- "Get Baked Goods Delivered"
- "Visit Our Artisan Bakery"
Insight: Many small businesses underestimate the power of A/B testing different headlines. By continuously measuring and tweaking, you can achieve significantly better results.
How do descriptions impact my ad performance?
Descriptions add context and detail to your ads, each allowing up to 90 characters. Here’s how to make them compelling:
- Add Details: Flesh out the value proposition. “Family-owned bakery offering the best artisan breads in town.”
- Include Reviews or Testimonials: "Rated 5 Stars by Local Foodies!"
- Reiterate Offerings: "Order Now and Enjoy Free Same-day Delivery!"
An effective description for a local plumbing service could be:
- "No call-out fees. Trusted by 10,000+ locals. Book your service today!"
How can I choose an effective Call to Action (CTA)?
Never underestimate the power of a clear, strong CTA. A well-crafted CTA tells potential customers exactly what you want them to do, reducing decision paralysis.
Examples:
- “Order Now”: Direct and succinct, ideal for businesses like restaurants.
- “Get a Free Consultation”: Works well for service-oriented businesses like law firms or consulting agencies.
- “Claim Your 10% Discount”: Enticing if you're running a special promotion.

How do I use negative keywords effectively?
Negative keywords help ensure your ads aren't shown to people who aren't your target audience, thus saving you money on irrelevant clicks.
- Identify Non-Converting Search Terms: Use Google Ads' search terms report to identify which terms are bringing irrelevant traffic.
- Add These as Negative Keywords: For example, if you're a high-end shoe retailer, you might use keywords like "cheap," "discount," or "bargain" as negatives.
- Monitor and Update: Regularly check which terms are triggering your ads and adjust your negative keyword list accordingly to refine targeting further.
What budgets should I set for Google Ads as a small business?
Your budget can significantly impact how you format and refine your ads. Keep these tips in mind:
- Average CPC: If your average CPC is around $2, and you want 100 clicks, budget at least $200 monthly. Adjust based on conversion rates.
- Split Testing Budget: Allocate funds for A/B testing, as this will inform what copy truly converts.
- Use Responsive Search Ads: These allow Google to test multiple headlines and descriptions automatically with the same budget, enhancing cost-effectiveness.

How often should I review and update my ad copy?
Consistent monitoring and adjusting are essential:
- Weekly Reviews: Check the performance dashboard to identify high/low-performing ads.
- Monthly Updates: Implement changes to underperforming ads based on data. This could include headlines, descriptions, CTAs, or targeting adjustments.
- Quarterly Audits: Conduct a thorough review of overall campaign performance, focusing on trends and adjusting the strategic direction accordingly.
Knowing how to read Google Ads reports is foundational for these updates, ensuring you know what actions to take based on your findings.
