The document discusses trends in universal search as identified in a Searchmetrics study. It finds that the number of organic search results has decreased from 10 to 8.5 on average, as Google integrates more knowledge boxes and other elements into search engine results pages. These elements include direct answers, related questions, images, videos and maps. The study also found differences between search results on smartphones versus desktops. Optimizing content to answer specific questions can help sites appear in direct answer boxes, while markup can also help with knowledge graph and image search results.
