01 Overview
Google Ads in brief.
Google Ads places ads where people search, watch and browse across Google's properties and partner sites. Search campaigns show text ads for the keywords you bid on, at the moment someone types a related query. Performance Max runs one campaign across all of Google's inventory from a single set of assets, and Demand Gen and video campaigns reach people on YouTube, Discover and Gmail.
The core skill is matching intent: choosing the searches worth paying for, writing ads that answer them, and sending the click to a page that delivers what the ad promised. Automated bidding now does most of the bid math, so clean conversion tracking matters more than manual bid changes.
A good fit
- Products and services people already look for by name or by problem
- Local and B2B services where a single lead is worth a lot
- Online stores with a product feed for Shopping and Performance Max
- Brands that want YouTube video alongside search
Think twice if
- Hardly anyone searches for your category yet; you'll need to create demand first, often on social or video
- Your category needs a Google certification (for example gambling, some healthcare or financial services) and you don't have it
- Your conversion tracking isn't in place; automated bidding depends on it
