How to Write High-Converting Google Ads Copy

A Google Search ad consists of up to 3 headlines (30 characters each), 2 descriptions (90 characters each), display URL with optional paths (15 characters each), and the final URL (your landing page).

Google assembles different combinations of your headlines and descriptions to find the best-performing mix. This means each headline should work independently and in combination with any other headline.

### Formula 1: Keyword + Benefit

Include the search keyword and state what the user gets. Example: "Emergency Plumber — 30-Min Response"

Formula 2: Number + Outcome

Use a specific number to add credibility. Example: "500+ 5-Star Reviews in Dubai"

Formula 3: Urgency + Action

Create time pressure. Example: "Book Today — Same Day Service"

Formula 4: Question That Resonates

Ask a question the searcher is thinking. Example: "Need a Plumber Right Now?"

Formula 5: Social Proof

Leverage trust signals. Example: "Dubai's #1 Rated Plumber"

Formula 6: Price or Offer

Lead with value. Example: "Free Inspection — No Call-Out Fee"

Formula 7: Differentiator

What makes you different. Example: "Licensed & Insured Since 2008"

Formula 8: Location-Specific

Reinforce local relevance. Example: "Serving All Dubai Communities"

When writing for Responsive Search Ads, you provide up to 15 headlines. Google tests different combinations of 2-3 at a time. Each headline should offer a unique angle so Google has meaningful variety to test.

Start with your keyword in at least 2-3 headlines, then write headlines covering benefits, offers/pricing, social proof, urgency, CTAs, location, and differentiators. Ensure no two headlines say the same thing in different words.

Descriptions have 90 characters — use them to expand on what headlines cannot cover. Include a detailed value proposition that supports the headlines. Add specific details (service hours, coverage area, guarantee terms). Include a call to action (Call now, Book online, Get a free quote). Mention trust signals if not covered in headlines (years in business, certifications, guarantees).

Pinning forces a specific headline to always appear in a certain position (1, 2, or 3). Use pinning sparingly because it reduces Google's ability to test combinations.

When to pin: Your business name or brand must appear (pin to Position 1). A legal disclaimer is required. A specific offer headline must always show.

When not to pin: In most other cases. Let Google test freely for the best results.

Google rates your RSA as Poor, Average, Good, or Excellent based on the number and diversity of headlines/descriptions, keyword inclusion, and uniqueness. Aim for "Good" or "Excellent" but do not sacrifice quality for score — a tightly written "Good" ad can outperform a padded "Excellent" one.

Run at least 2 RSAs per ad group at any time. After 2-4 weeks of data, review asset performance (go to Ads > click an RSA > View asset details). Replace headlines and descriptions rated "Low" with new variations. Keep assets rated "Best" and "Good."

Do not test too many things simultaneously. Change 2-3 assets at a time so you can attribute performance changes.

Using all caps (violates policy and looks spammy), making exaggerated claims without evidence, writing generic copy that could apply to any business, not including the keyword (hurts ad relevance and Quality Score), identical headlines with minor wording differences (wastes testing capacity), ignoring the mobile experience (most users see ads on mobile — front-load key information).
