Google has removed all PPC ads from the right-hand side of the search engine results page with immediate global effect. The change has already happened.
Why did Google remove the ads? – Google is ‘mobile first’ due to mobile searches beginning to overtake desktop searches, and this move makes for a similar user experience across both. With fewer sponsored links, the overall quality should improve. The lowest position links (9,10,11) are the ones Google has deemed least likely to appeal to the user, and so removing them means that the quality of the remaining links is improved. When there are fewer positions advertisers will have to bid more to get on the first page, and there’s much more incentive to hike bids to achieve position four.
