Perhaps when we talk about the content network or the Google Display Network, we don't know exactly what the person talking to us about these topics is referring to. We must keep in mind that to fully understand everything we can learn about Google AdWords, we must be able to understand the tool's enormous potential.
When we refer to the Google search network, we're not just referring to the Google search engine. We could give many figures about it, such as the fact that 100 billion search queries are made on the search engine, which means 3.333 billion queries per day, or more than 38,576 queries per second! But this figure has most likely increased since this post was written. We want to emphasize that when we refer to the search network, we're not just talking about the search engine itself, but also Shopping, Maps, Images, and Groups, as well as search partner sites like AOL. The Display Network was previously called the Content Network, so we'll refer to it as the Display Network, even though the term "Content Network" sometimes escapes the more nostalgic among us. This network is made up of more than a million web pages , videos, and mobile apps where Google ads can appear in the form of graphic ads, text, videos, and so on. This figure, of course, is constantly growing. But it's undoubtedly of an unparalleled size. It's very important to differentiate between the two main networks, as it will be very useful to know how to differentiate them in order to implement a correct strategy in our Google AdWords campaigns.
