Will Google's Sidebar Ads Ever Return?

Digital advertisers did a double-take at Google AdWords announcement they are removing ads from the right hand sidebar of its search results page. 


The change impacts SEO professionals and advertisers alike. Instead of seeing AdWords PPC listings in the sidebar, users will either be presented a blank space, Product Listing Ads or the Knowledge Graph results. 


Those same users will also see more at the top of the actual search results from three links to four. SEOs will see their coveted first position bumped down from the initial field of view (when a sufficient amount of ads are in play) and advertisers will have fewer spots to bid for (which will drive up the cost per click over time).
