You can access Google Ads Networks in the campaign settings tab, right below the campaign name.
Search Network – this allows your ads to show on Google’s partner websites.
This option is not recommended for beginners or advertisers who have limited budgets, even if it’s for a search campaign. The reason is that people who use other websites within Google network don’t have the same intent. Those who search on Google are more likely to convert as compared to those who search for the same keywords on other websites such as Youtube.
Display Network – it takes the information that we put in the ad and put them on different websites that are a part of the network. This option is not recommended for search campaigns. The chances of people clicking and buying is very low. There’s no search intent in the Display Network.
