Beginning in April 2016, Custom Search Engine will no longer show any right-hand side ads and will no longer offer an option to remove ads above the search results.
Google will show up to four ads above the search results. Search Results will expand to fill the area previously occupied by right-hand side ads. This change improves the aesthetic of the search results and ads across a variety of screen sizes and devices, providing a more consistent and enhanced user experience.
The option to remove ads above the results has been removed from Custom Search Engine. Custom Search Engines that were previously configured to remove these ads will now begin showing ads above the results.
