Structured Snippet Extensions

Structured Snippet Extensions (now called Structured Snippet Assets) are Google Ads assets that display a category header followed by a list of specific values, such as “Services: SEO, PPC, Social Media, Content Marketing.” They provide structured, scannable information about what you offer and are non-clickable.

Key Takeaways

• Structured snippets use predefined headers (Brands, Services, Types, etc.) followed by your custom values
• Non-clickable — they inform rather than drive clicks to specific pages
• Minimum of 3 values required per header; Google recommends 4 or more
• Each value has a 25-character limit
• Multiple headers can be created, and Google selects the most relevant per auction

What Are Structured Snippets

Structured Snippets give users a quick, organized overview of specific aspects of your business. Unlike Callout Extensions (which are freeform text), structured snippets follow a header:value format that creates a consistent, scannable presentation.

Available headers in the 2026 Google Ads interface:

Header	Best For	Example Values
Amenities	Hotels, venues	Pool, Spa, Gym, Free WiFi
Brands	Retailers, distributors	Nike, Adidas, New Balance
Courses	Education, training	Data Science, Machine Learning, Python
Degree programs	Universities	MBA, Computer Science, Engineering
Destinations	Travel, airlines	London, Paris, Tokyo, Dubai
Featured hotels	Travel agencies	Hilton, Marriott, Hyatt
Insurance coverage	Insurance	Auto, Home, Life, Business
Models	Auto, technology	Model X, Model Y, Model 3
Neighborhoods	Real estate, local services	Downtown, Midtown, Westside
Service catalog	Professional services	Consulting, Implementation, Support
Shows	Entertainment, venues	Hamilton, Wicked, Lion King
Styles	Fashion, design	Modern, Contemporary, Minimalist
Types	General category listing	Residential, Commercial, Industrial

How It Works

Setting up structured snippets:

1. Navigate to Ads & assets > Assets and select Structured Snippets
2. Choose a header that matches an aspect of your business you want to highlight
3. Enter at least 3 values (4+ recommended) that fall under that header
4. Create multiple headers — Google will pick the most relevant one per auction
5. Assign to account, campaign, or ad group level as appropriate

Google displays structured snippets as a single line below your ad text: Header: Value 1, Value 2, Value 3, Value 4

The system selects which header to show based on:

• Relevance to the search query
• Space available on the results page
• Performance history of each header
• Compatibility with other assets being shown

Structured snippets are distinct from Callout Extensions in both format and purpose:

Dimension	Structured Snippets	Callouts
Format	Header: list of values	Standalone phrases
Purpose	Categorize offerings	Highlight benefits
Example	”Types: Sedan, SUV, Truck"	"Free Oil Change With Purchase”
Flexibility	Must use predefined headers	Freeform text

Practical Example

A commercial cleaning company creates structured snippets at the campaign level:

Header 1 — Service catalog: Values: Office Cleaning, Floor Care, Window Washing, Carpet Cleaning, Post-Construction, Sanitization

Header 2 — Types: Values: Daily Service, Weekly Service, Monthly Service, One-Time Deep Clean

The ad appears as:

Commercial Cleaning Services | Get a Free Quote Professional cleaning for offices and commercial spaces. Licensed, insured, and trusted since 2005. Service catalog: Office Cleaning, Floor Care, Window Washing, Carpet Cleaning, Post-Construction Free Estimates — 24/7 Availability — Licensed & Insured — Eco-Friendly Products

Performance over 45 days comparing ads with and without structured snippets:

Metric	Without Snippets	With Snippets	Impact
Impressions	18,000	18,000	—
CTR	5.4%	6.1%	+13%
Clicks	972	1,098	+126
Conversions	58	72	+24%
CPA	$84	$76	-10%

The “Service catalog” header was shown in 72% of impressions, while “Types” appeared in 28%. The service listing helped users immediately understand the company’s capabilities, pre-qualifying clicks from businesses that needed those specific services.

Why It Matters

Structured snippets serve a distinct role in the ad asset ecosystem: they tell users exactly what you offer in a scannable format. While headlines and descriptions persuade, and Sitelinks provide navigation, structured snippets provide at-a-glance inventory of your products, services, or categories.

This pre-qualification effect is their primary value. When a user sees “Services: SEO, PPC, Social Media, Content Marketing” they can instantly determine whether you offer what they need. Users whose needs align are more likely to click; users whose needs do not match are less likely to waste your budget with an irrelevant click. The result is higher-quality traffic and lower cost per acquisition.
