- Definition: Call extensions are advertisers features that display a phone number or call button within search ads, display ads, or video ads, allowing users to initiate a phone call directly from the advertisement without navigating to a landing page. They appear as clickable elements on mobile devices and desktop, often accompanied by a headline or description text.
- Purpose: The primary goal is to capture high-intent leads who prefer speaking to a representative over filling out a form. Call extensions reduce friction in the conversion process by enabling immediate connection, which typically leads to higher conversion rates for services like insurance, healthcare, and automotive repair.
- Types: Two main types exist: click-to-call extensions, which display a phone number that users can tap to call, and call-only ads, which are exclusively designed for phone calls with no option to visit a website. Call-only ads are ideal for businesses where phone calls are the primary conversion action.
- How they appear: On mobile search results, call extensions show as a phone icon or clickable number under the ad headline. On desktop, they may appear as a phone link or a small call button. Ad platforms like Google Ads and Microsoft Advertising automatically optimize the format based on user device and context.
- Eligibility: To use call extensions, advertisers must have a verified business phone number, a website that is mobile-friendly, and must comply with local telemarketing regulations. The ad account must also have conversion tracking set up to measure call performance.
- Reporting: Platforms provide metrics such as call clicks, call duration, and conversion tracking via Google Forwarding Numbers (Google Ads) or third-party call tracking services. These reports help advertisers assess the effectiveness of phone leads and make data-driven decisions.
- Differences from sitelinks: While sitelinks direct users to specific pages on a website, call extensions are unique because they bypass the landing page entirely. This makes them suitable for urgent needs like roadside assistance or same-day appointments where speed is critical.
- User experience: Call extensions improve user experience by offering a one-tap option for mobile users, reducing typing and navigation. They also build trust by providing a direct line of communication, which can increase click-through rates for local service businesses.
