Google still plans to remove featured snippets from the right rail on desktop and move the feature into the main listings. URLs shown in featured snippets that appear in the right rail of Google desktop results will continue to be included in the main organic listings, for the time being, anyway.
More on the news Deduplication only occurs for the exact URL in the featured snippet, and only on the first results page; it does not occur for other rich results, such as video featured snippets, Top Stories or Interesting Finds. Main column featured snippet deduplication rolled out globally on January, 22, 2020. During the initial featured snippet deduplication, many featured snippet URLs were also appearing as the first listing on the second results page. Google has clarified that this was not by design. URLs used in main column featured snippets are no longer appearing within organic results at all, according to search analytics company Rank Ranger.
