  In this paper authors analyzed 50 000 keywords results collected from
localized Polish Google search engine. We proposed a taxonomy for snippets
displayed in search results as regular, rich, news, featured and entity types
snippets. We observed some correlations between overlapping snippets in the
same keywords. Results show that commercial keywords do not cause results
having rich or entity types snippets, whereas keywords resulting with snippets
are not commercial nature. We found that significant number of snippets are
scholarly articles and rich cards carousel. We conclude our findings with
conclusion and research limitations.
