The folks at RankRanger came out with a study around Google’s featured snippets that shows that on average a featured snippet from a specific site will only be swapped out with a different site but it is rare for it to be swapped out to a third site. Even more, the dominant URL will show 77% of the time, as opposed to the second URL.

This all means to me that featured snippets and their placements are more consistent than I thought.

I covered this yesterday at Search Engine Land with the title Coveted featured snippet space is more exclusive than you think, study shows.

Here is Mordy’s tweet on the study:

Now, don’t get me wrong, a 3rd URL can show, the featured snippet in its entirety can disappear also. But this study is pretty interesting.
