Over the past few months I've been seeing blog post of the type 100 Best Widgets rank in the top 3 results where collections e.g. category style pages used to rank. In most cases these blog posts are at the same time being used for Featured Snippets Lists. They don't always rank #1 but they grab position #0. It seems clear that their sudden appearance at the top of the SERPS is related to their being used as featured snippets.
I've been trying all sorts of changes to HTML structure and content of the items listed on the category pages to make them more like lists, but have seen success for only a day at most. Even though my category pages are still ranking in the top 3 I can't grab position 0.
My questions are:
1. Are category pages ranking for Featured Snippets Lists?
2. Have blog posts seen a boost over Category pages lately?
Does Google prefers blog posts for Featured Snippets Lists over collection style groups of pages such as taxonomy style pages. e.g. categories, tags, products
2. Is it possible that the preference is due to pagination? i.e. Google doesn't use Paginated content for Featured Snippets Lists AND If so is this a feature or a bug?
