Google’s John Mueller said there is no rule that a page has to rank in the top ten search result positions for it to be considered eligible for a featured snippet position.
The question was asked by Shubham Davey who wrote “if a page isn’t ranking in the top 10 on SERPs, are those pages eligible for featured snippets?”
John Mueller replied on Twitter, “I don’t think there’s any hard rule like that; that would be weird.”
Here are those tweets:
Pete Meyers from Moz also added his thoughts:
While it doesn’t have to be the case where a featured snippet must be from a page that would rank well, it probably is mostly the case.
