Google Ads is Google’s advertising platform and the largest in digital advertising. It gives advertisers access to Google Search, YouTube, Gmail, Discover, Maps, and the Google Display Network from one platform. Together these properties reach users across nearly every online touchpoint.
Search advertising
Search campaigns place text ads in Google Search results when users actively look for products or services. Ads appear at the top and bottom of the results page. Keywords trigger which ads show. Smart Bidding adjusts bids in real time using auction-time signals — device, location, time of day, and more. In 2025, Google introduced AI Max for Search. It’s a suite of AI features that layers onto existing campaigns to expand keyword coverage and improve match quality.
Performance Max
Performance Max (PMax) runs a single campaign across Search, Shopping, YouTube, Display, Gmail, Discover, and Maps. Advertisers provide creative assets and audience signals. Google’s AI handles placement, bidding, and optimisation across all channels. PMax reports results by channel, so advertisers can see where budget works across the full mix.
Shopping and video
Shopping campaigns display product listings with images, prices, and store names directly in search results. They run from a product feed rather than manual keywords. Video campaigns run on YouTube and Google‘s video partner network. Formats include skippable in-stream ads and bumper ads. Demand Gen campaigns reach over 3 billion monthly active users across YouTube, YouTube Shorts, Discover, and Gmail.
Audience targeting
Google Ads targeting covers demographics, in-market audiences, affinity segments, and custom intent. Customer Match lets advertisers upload CRM data to target existing customers directly. Lookalike segments find new users who share characteristics with existing customers. Remarketing lists re-engage users who visited a site or app. Smart Bidding Exploration (introduced in 2025) expands beyond core keyword targets. It finds converting queries advertisers haven’t explicitly bid on, widening reach without manual keyword research.
Measurement
Google Ads integrates with Google Analytics 4, Google Tag Manager, and the full GMP stack. Conversion tracking covers web, app, phone calls, and store visits. Data-driven attribution distributes credit across touchpoints based on actual contribution to conversion.
