TL;DR: Featured snippets are an organic search feature that now take significant search traffic from the search results below them. Featured snippets run on a separate algorithm than Google's traditional 200 ranking signals. To understand these signals, HubSpot’s SEO team ran a series of experiments and, together with the blog and web teams, developed a process for featured snippet optimization. The result: a clean code that allows you to capture featured snippets and a guide with best practices for optimizing your content for Google's featured snippet.
