Text Ad Structure
A Google responsive search ad consists of three main components: headlines, descriptions, and the display URL.
Headlines
Headlines are the most visible part of your ad. Users are most likely to notice the headline text first.
- Fields: Up to 15 headline fields, each max 30 characters. Google rotates and tests combinations automatically.
- Display: Up to 3 headlines show at once, separated by a pipe ("|")
- Tip: Include at least one keyword in your headline — this demonstrates relevance to the user's search query
Consider how longer headlines wrap on mobile devices. Test different headline lengths to optimize for both desktop and mobile.
Descriptions
Descriptions provide detailed information about your product or service's unique value proposition.
- Fields: Up to 4 description fields, each max 90 characters
- Display: Up to 2 descriptions show at once
- Tip: Highlight your unique advantages — free shipping? Wide selection? Promote what makes you competitive
Include pricing, promotions, and exclusive offers. Users frequently search Google to find information and complete tasks — provide the information they need to make decisions.
Display URL
The display URL shows your website address, giving users an idea of where they'll land after clicking.
- Final URL: The actual landing page URL
- Path fields: Two optional path fields, each max 15 characters, that customize the display URL
- Tip: Ensure ad-to-landing page consistency — verify the landing page contains the promotions or products advertised
Best Practices
- Use keyword insertion: Dynamically insert the user's search term into your headline
- Add clear CTAs: "Buy," "Call Now," "Order," "Browse," "Sign Up" — tell users what to do next
- Test multiple variations: With responsive search ads, Google automatically tests combinations
- Pin headlines: Pin critical headlines to position 1, 2, or 3 to control messaging
- Monitor ad strength: Aim for "Excellent" ad strength by providing diverse, relevant headlines
