Unlike the search network, the Display Network allows you to display both text ads as well as image ads. So you can create ads in jpeg, png, flash, HTML 5, GIF or using the Ads Ad Builder tool, in the form of banners to promote a brand, a product or a message. These ads must adhere to a specific format in order to be published, the specifications for each format are available on Google Ads support.
Flash ads are automatically converted to HTML 5 when uploaded to Ads for display on as many platforms as possible. The display network ads are not only displayed on search pages or those of its partners, they are displayed in specific locations on sites participating in the Ad Network or Toronto advertising agencies program.
Specific locations are defined on these sites in the form of squares or rectangles corresponding to the different ad formats.
