Currently ads in CSE results are shown in a separate section from organic search results labeled “Ads by Google”. With this latest change, the ads section will also have a distinct background color, in keeping with the visual style of ads on the google.com search results page.
Because CSE allows you to choose from one of several built-in styles, the ads background color is different for each style to contrast in a visually appealing way with the default background color. (Note that if you customize the main background color, the ads background color will automatically match it to avoid clashing.)
The following screenshots illustrate what a user performing a custom search on a website might see, for two of the built-in CSE styles.
This change in design provides users another way to distinguish ads in CSE search result pages.
CSE publishers will see these changes effective immediately. As always, please let us know any questions or feedback in our discussion forum.
