When Google recently removed all text ads from the right rail of search engine results pages (SERPs), it caused quite a stir among both advertisers and webmasters who rely on organic traffic for their business. The change in design and the number of ads on SERPs pushes even more organic results below the fold and makes the competition even fiercer for both top ad spots and top organic listings.

Google has been overall fairly tight-lipped about the changes, only confirming that it has occurred and implying the change was largely aimed at bringing the desktop search experience more in line with the mobile search experience.

While it’s not an official statement, Google employee Matt Lawson recently went into depth on why Google decided to cut text ads from the right side of search results and how it could affect your pages and advertising account.

It largely confirms what was already suspected: Right side ads performed poorly and they wanted to bring mobile and desktop search closer together. However, Lawson provides data to show exactly how they expect the change to affect advertisers and steps you can take right not to mitigate any changes in your CPCs and ad performance.
