Why does Google offer so many ad types?
Google is not just a search engine — it's an ecosystem that includes a video platform, a maps app, a shopping interface, and millions of partner websites. Each surface reaches a user at a different moment of intent. Someone watching YouTube over morning coffee and someone searching "dentist near me" at night are in completely different mindsets. That's why Google has built a separate ad type for each stage of the customer journey.
The six main ad types and what each one does
- Search Ads — Text-based ads that appear when someone actively searches on Google; this is the highest-intent audience you can reach.
- Performance Max — A single campaign type powered by Google's AI that covers Search, YouTube, Gmail, Maps, and the Display Network simultaneously.
- YouTube Ads — Video ads used for brand awareness and product discovery; available in skippable, non-skippable, and bumper formats.
- Shopping Ads — Show your product photo, price, and store name directly in search results; built for e-commerce businesses.
- Demand Gen — Visual ads designed to spark interest when people are not actively searching, shown in YouTube feeds, Gmail, and Discover; this replaced Discovery campaigns.
- Display Network (GDN) — Banner, image, or animated ads placed across millions of Google partner websites and apps; widely used for retargeting.
starts with a Google search — according to Google's own data, the vast majority of shoppers search before buying. That makes Search Ads the logical first step for most small businesses.
What changed in 2026: formats no longer available
Expanded text ads (ETAs) have been retired by Google and replaced by Responsive Search Ads (RSAs). Discovery campaigns have been rebranded and rebuilt as Demand Gen. Universal Analytics is gone, with measurement now built on GA4. If an agency or resource still presents these older formats as current, their knowledge is at least a year or two out of date.
