Ad assets (formerly called ad extensions) are additional pieces of information attached to Google Ads — including sitelinks, callouts, call buttons, structured snippets, image assets, and lead forms — that expand ad real estate and improve click-through rates.
Quick Answer
Ad assets (formerly called ad extensions) are additional pieces of information attached to Google Ads — including sitelinks, callouts, call buttons, structured snippets, image assets, and lead forms — that expand ad real estate and improve click-through rates.
Ad assets are now automatically selected by Google's systems — providing 8–10 of each asset type gives the algorithm more combinations to optimize across different queries and audiences.
Ad Rank incorporates the expected impact of assets, meaning strong asset configuration can improve position against competitors with higher bids but weaker assets.
Lead form assets reduce friction by capturing leads directly from the SERP — particularly effective for B2B campaigns where landing page load time and form complexity reduce conversion rates.

How Ad Assets Works
Google renamed "ad extensions" to "ad assets" in 2022 to better reflect how they function: as modular content components that Google's systems automatically select and combine with your core ad based on predicted performance. Assets include sitelink assets (additional destination links), callout assets (short highlight phrases like "Free Consultation" or "No Contracts"), structured snippets (lists of services, products, or features), call assets (phone numbers), location assets, image assets, lead form assets, price assets, and promotion assets.
Why Ad Assets Matters for B2B Marketing
Ad assets improve performance by increasing the physical size of your ad on the SERP, which lifts click-through rates, and by providing additional relevance signals that contribute to Ad Rank. Google's Ad Rank formula incorporates "expected impact of ad extensions" — meaning a well-configured asset setup can improve your position relative to competitors bidding higher CPCs but with fewer or less relevant assets. Adding sitelinks alone has been shown in Google studies to increase CTR by an average of 10–20% versus ads without sitelinks.
Ad Assets: Best Practices & Strategic Application
Not all assets appear with every ad impression. Google selects asset combinations based on the search query, user context, and predicted click-through rate. This means you should provide more asset content than will ever appear simultaneously — typically 8–10 sitelinks, 8+ callout assets, and 3–4 structured snippet headers. Higher asset quantity gives Google more combinations to test and increases the likelihood that the right message appears for each query. Asset performance is visible at the asset level in your Google Ads account under the "Assets" tab.
Agency Perspective: Ad Assets in Practice
For B2B lead generation campaigns, the highest-impact assets include: sitelinks pointing to specific service pages, case studies, and pricing; callout assets highlighting proof points and differentiators; structured snippets listing service types or industry verticals; and lead form assets that capture contact information directly within the ad without requiring a landing page click. Image assets add visual differentiation in search results and should include high-quality product or team images. Review assets, where eligible, display star ratings and improve credibility for branded and competitor keywords.
Frequently Asked Questions: Ad Assets
Ad assets (formerly called ad extensions) are additional pieces of information attached to Google Ads — including sitelinks, callouts, call buttons, structured snippets, image assets, and lead forms — that expand ad real estate and improve click-through rates.
Yes — there is no additional cost to add assets to your ads. You pay only when users click on your ad or interact with specific asset types. Some asset types like call assets charge per call click, and lead form asset submissions are counted as conversions. Adding assets increases CTR (and therefore total spend) but does not add cost per click for the core asset types.
Google recommends adding at least 4 sitelink assets at the campaign level; adding 8–10 gives the system more options to test and rotate. Each sitelink should point to a distinct, relevant destination with a unique 25-character headline and two 35-character description lines. Avoid duplicating your main ad's landing page as a sitelink — each link should offer genuine additional value like a specific service, case study, or pricing page.
Callout assets are short (25 characters max) freeform phrases that highlight key selling points — "No Setup Fees," "Certified Google Partners," "24/7 Support." Structured snippets follow a predefined format with a header (e.g., "Services:") followed by a list of values (e.g., "SEO, PPC, Web Design, Content Marketing"). Use callouts for unique differentiators and structured snippets for organized lists of offerings, industries, or features.
