Google Ads Extensions: Every Type Explained (With Examples)

From Extensions to Assets: What Changed

If you've been running Google Ads for more than a couple of years, you know the feature formerly called "ad extensions" — those extra lines of text, links, and images that show beneath your standard ad. In 2022 Google quietly renamed them "assets" across the platform. Same feature, new label, slightly different reporting interface.

The renaming wasn't cosmetic. Assets now sit at the heart of how Google assembles search ads, especially in Responsive Search Ads (RSAs) and Performance Max. Google's algorithm decides in real time which combination of headlines, descriptions, and assets to display for any given auction. Your job is to give it enough material to work with — and to make sure the material is good.

Why Assets Matter More Than Ever

According to Google's own asset documentation, ads with relevant assets consistently see higher click-through rates. The Think with Google team has cited 10-15% CTR lifts as typical when accounts move from minimal assets to full coverage. That's free performance — assets cost nothing extra to run.

They also feed Ad Rank. Google factors expected asset impact into the auction calculation, which means a competitor running the same bid as you but with weaker assets will lose. We covered Ad Rank and Quality Score in depth in this companion article.

The Three Categories

Assets break into three groups: text-based (sitelinks, callouts, structured snippets), action-oriented (call, lead form, location, price, promotion, app), and visual (image, logo, business name). Most accounts should be running every text-based asset and at least one or two from each of the other groups.

Sitelink Assets

Sitelinks are additional clickable links that appear beneath your main ad, each pointing to a different page on your site. They're the workhorse asset — present on virtually every well-built campaign — because they expand your ad footprint and let users self-select the page most relevant to them.

What a Good Sitelink Looks Like

A useful sitelink has a short, action-oriented title (under 25 characters) and two short description lines that reinforce value. Here's a passable example for a software company:

Sitelink Levels and Targeting

You can attach sitelinks at the account, campaign, or ad group level. More specific levels override broader ones. For most accounts, that means a baseline of 8-10 evergreen sitelinks at the account level, with campaign-specific sitelinks for top campaigns and seasonal promotions.

Common Mistakes

• Pointing all sitelinks at the same page defeats the purpose. Each link should land on a distinct, relevant URL.
• Using vague titles like "Learn More" or "About Us" wastes the asset slot. Be specific.
• Too few sitelinks. Google recommends 8 or more. Fewer than 4 and the asset won't show in many auctions.
• Skipping descriptions. Sitelinks with descriptions take more visual space and earn higher CTR.

Callout and Structured Snippet Assets

Callouts and structured snippets are the unsung heroes of asset strategy. They don't link anywhere — they exist purely to add credibility lines to your ad — and they're easy to implement, easy to test, and easy to forget.

Callout Assets

Callouts are short text snippets (up to 25 characters) that highlight selling points: "Free Shipping," "24/7 Support," "30-Day Returns," "Family-Owned Since 1987." Add at least 6-10 per campaign and let Google rotate them. Avoid duplicates with your headlines — callouts should add information, not repeat it.

Structured Snippet Assets

Structured snippets are list-format assets organized under predefined headers like "Brands," "Models," "Services," "Types," or "Destinations." For example, a hotel chain might add a Destinations snippet listing "London, Paris, Rome, Tokyo, Sydney." The header tells Google what category of information you're providing, which helps it decide when to show the asset.

When to Use Each

Per Search Engine Journal, accounts running both callouts and structured snippets together see higher CTR than those running either in isolation. They reinforce each other rather than compete for ad real estate.

Call and Location Assets

For local businesses, call and location assets are arguably more important than sitelinks. They turn search ads into direct funnels for the actions you actually want — phone calls and store visits.

Call Assets

Call assets attach a phone number to your ad. On mobile, the number becomes a tap-to-call button; on desktop, it displays as a clickable number. You can use a Google forwarding number to track call duration and outcomes through conversion tracking.

Schedule call assets to appear only during business hours so you don't pay for clicks that lead to voicemail. Use call-only ads for service-based businesses where the phone call is the conversion: emergency plumbers, tow trucks, lawyers, dental offices.

Location Assets

Location assets pull from your linked Google Business Profile and display your business address, hours, and a map pin. They make your ad eligible for the Google Maps placement and dramatically improve relevance for "near me" queries.

Affiliate location assets work similarly but for businesses sold through retailers. A consumer brand can show which nearby stores stock its products without managing those locations directly.

Real-World Impact

I've seen multi-location service businesses double their lead volume just by enabling location and call assets they had previously ignored. The combination signals trust ("they have a real address"), proximity ("they're near me"), and immediacy ("I can call right now"). All three matter to local searchers.

Image, Lead Form, and Price Assets

The newer asset types — image, lead form, and price — represent Google's ongoing push to make search ads richer and more interactive. They take more setup effort, but the payoff is usually worth it.

Image Assets

Image assets attach a photo to your search ad on mobile, dramatically increasing visual prominence. Use product photos, store interiors, or service-in-action shots — never stock photos. Google requires images to be at least 600x314 pixels and bans text overlays, logos, and excessive whitespace.

Image assets work best for visual-first businesses: home services, retail, hospitality, automotive. Less effective for abstract services like SaaS or insurance, though even there they can lift CTR when paired with a compelling product screenshot.

Lead Form Assets

Lead form assets let users submit their contact info without leaving the search results page. Google pre-fills name and email from the user's Google account, so the form is effectively two taps away. For top-of-funnel offers (newsletter, free guide, demo request), lead form assets often outperform standard landing page funnels because they remove every step except submission.

Price Assets

Price assets display a list of products or services with prices directly in the ad. They're especially powerful for businesses competing on price or transparency — and they help filter out price-sensitive clickers who would have bounced anyway. That makes them a quiet weapon for click quality.

App, Promotion, and Affiliate Assets

The remaining asset types are situational but high-leverage when they fit your business model. Skipping them when they apply is leaving free performance on the table.

App Assets

App assets prompt mobile users to download your iOS or Android app directly from the search ad. They're essential for app-driven businesses (banking, food delivery, ride-share) and a useful complement for any business with a mobile app, even if web is the primary channel.

Promotion Assets

Promotion assets highlight discounts and special offers with structured fields for occasion ("Black Friday"), discount type ("15% off"), and applicable products. They display with a distinctive tag-style icon that draws the eye, and they let you schedule promotions so they switch on and off automatically.

The discipline trick: set a clear expiration date, even on evergreen offers. Promotions that look perpetually available stop feeling like promotions.

Affiliate Location Assets

If you're a manufacturer selling through retailers — appliances, consumer electronics, packaged goods — affiliate location assets show shoppers where to buy your product nearby. They convert search interest into in-store visits without you having to operate retail locations.

Business Logo and Name Assets

These show your brand logo and name alongside your ad on mobile and feed Google's brand recognition signals. Verifying these assets through Google's advertiser identity program is increasingly required for top placements. If you haven't enabled them, do it this week.

Asset Strategy and Best Practices

Knowing what each asset does is the easy part. Using them well across a real account takes a bit of system thinking.

Coverage Targets

• Sitelinks: 8-10 at the account level, plus campaign-specific where possible
• Callouts: 8-10 at the account level, refreshed quarterly
• Structured snippets: 2-3 different headers, each with 4-6 values
• Images: 5+ per campaign, varied subjects
• Calls: One per campaign with business-hours scheduling
• Locations: Linked Google Business Profile
• Lead forms: One per campaign for top-of-funnel offers

Test Variants Continuously

Asset rotation is the simplest A/B test in Google Ads — just upload multiple variants and let Google's auction-time selection do the work. Add new sitelink and callout variants every 4-6 weeks, then check the asset reporting tab to see which earned the most clicks. Pause the bottom 20% and add fresh variants to take their place.

Campaign-Level vs Account-Level

Use account-level assets for evergreen messaging that applies everywhere ("Free Shipping," "24/7 Support"). Use campaign-level assets for offers and angles specific to a particular product line or audience. Avoid duplicating an account-level asset at the campaign level — it will override but not stack.

Pair Assets With Negative Keywords

Even the best assets won't save your CTR if your campaigns are showing on irrelevant queries. Pair your asset overhaul with a negative keyword cleanup using our negative keywords guide. The two together compound.

Measuring Asset Impact

Asset reporting in Google Ads is decent but easy to misread. Here's how to extract real signal from it.

Where to Find Asset Data

Inside any campaign, click the Assets tab. You'll see each asset listed with impressions, clicks, CTR, and a performance label: Best, Good, Low, Pending, or Learning. Google assigns these labels by comparing variants within the same asset type — so a "Low" callout in your account might still outperform a "Best" callout in another account.

What to Act On

• Pause "Low" performers after they've accumulated at least 2,000 impressions.
• Duplicate "Best" performers with small variations to find your next winner.
• Ignore "Learning" labels until enough data accumulates — usually 4-6 weeks for new variants.

The Hidden Metrics

Don't stop at CTR. Pull conversion data for assets where you have enough volume — sometimes the asset with the highest CTR has the lowest conversion rate, attracting curious clickers but not buyers. Optmyzr's research blog documents repeated cases where pausing a "Best" asset because of poor downstream conversion lifted account-level ROAS.

Tying Asset Health to Account Health

Run a monthly asset audit alongside your standard performance review. Ask: Are all asset types active? Are coverage targets being met? Have I added new variants this month? Have I paused poor performers? An hour a month of asset hygiene typically returns 5-15% in account-level performance over time.
