Ad Extensions

Definition — Ad Extensions

Ad extensions (now called assets in Google Ads) are additional pieces of information added to Google Ads that expand your ad with links, phone numbers, addresses, callouts, prices, and other details, increasing ad real estate and click-through rates. For SaaS companies, using all relevant extension types is a quality signal and a free way to improve ad visibility and qualified click rates.

What are Ad Extensions (Assets)?

Ad extensions (renamed Assets by Google Ads in 2022) are additional pieces of information attached to standard search ads that expand the ad and provide more context to potential clickers: sitelink extensions (additional navigation links), callout extensions (brief product highlights), call extensions (phone numbers), lead form extensions (native in-search lead capture), price extensions (pricing information), image extensions, and more. Extensions do not increase your cost-per-click (you pay the same whether or not extensions show), but they typically improve CTR by 10-15% by making your ad more informative and visually prominent.

Most Valuable Extensions for SaaS Companies

Priority extensions for SaaS Google Ads: (1) Sitelink extensions: direct links to key pages (Pricing, Free Trial, Case Studies, Features): 15-20% CTR improvement on average. (2) Callout extensions: short benefit highlights (No contracts, SOC 2 certified, 24/7 support): strengthen the ad value proposition without adding links. (3) Lead Form extensions: collect trial signup or demo request information directly in the search results: effective for mobile where landing page friction is higher. (4) Image extensions: appear alongside ads on eligible queries, significantly increasing visual prominence. (5) Structured snippet extensions: highlight specific features, integrations, or product categories in a formatted snippet.

Frequently Asked Questions

Do ad extensions automatically show with every ad?

No. Google Ads shows extensions when its algorithms predict they will improve the ad performance given the specific auction: the query, the user, the device, and the competition. An ad may have 10 extensions configured but Google may show only 2-3 per impression based on space availability and predicted CTR improvement. Google prioritizes showing extensions that increase the probability of clicks and conversions for each specific query. Ensure all extensions are enabled and well-written; the algorithm selects which ones to show dynamically per auction.

How should sitelink extensions be written for SaaS ads?

Effective SaaS sitelink copy: short (25 characters max), specific (avoid generic Learn More or Click Here), benefit or destination-focused (Start Free Trial, See Pricing, Watch Demo, View Case Studies), and differentiated from each other (do not use four variations of the same offer). The best sitelinks for SaaS map to the natural next steps in the buyer journey: a user seeing an awareness ad might see Blog, Guides, and Case Studies sitelinks; a user seeing a comparison keyword ad might see Pricing, Free Trial, and Competitor Comparison sitelinks. Configure different sitelink sets at ad group level for different keyword intent groups.
