Yes, Dilan, “This “Diversity update” is designed to make it so that one site will rarely have more than two listings on the first page of the organic search results.”https://twitter.com/searchliaison/status/1136739062843432960
Yeah, In 2010 Google launched the changing algorithm on the search results and it will make it much easier for users to find a large number of results in a single site. Again 2012 & 2013 Google showed fewer results from the same domain name. After that, in 2019 June they have done this change for the users. But it only impacts the core results, not the additional search features such as top stories, video snippets, image carousels or other vertical search features listed among the other web results.
