During Gary Illyes’ keynote at State of Search in Dallas, he talked quite a bit about featured snippets and gave some advice for those who are looking to get into the featured snippets.

He said pages should either implicitly or explicitly state the question on the page, then answer the question.

While he didn’t go into further detail, we know from the search quality guidelines that Google likes to show featured snippets that can be answered in 1-2 sentences.   And this is definitely the type of results we see in featured snippets.

But anytime content is involved, it does bring up the role of Panda, especially when creating new content.  If your answer is quality, you shouldn’t worry about it.  That said, you will probably want to provide more detail below your 1-2 sentences, but again ensuring it is quality content and not just filler to fluff up the word count, ala college essay style.

You can also use your Search Analytics in Google Search Console to discover any featured snippets you currently have but might not be aware of.
