Google Clarifies That the Passage Indexing Has More to Do with Ranking than Indexing
https://www.seroundtable.comGoogle clarifies that the Passage Indexing announcement has more to do with ranking than indexing. Google has not changed how it indexes when it comes to this, it still indexes the full page.
Google’s systems will consider the content and meaning of passages when determining what is most relevant versus previously they were largely looking at the page overall. So indexing really has not changed here. It is more of a ranking change, how Google ranks content, based on what it finds on your web page.
