How to Read Search Engine Results Pages
Stay current with News results.
Another significant search-result component is the news results. If the search engines think News results might be useful to you, based on your search — search for obama or just about any country name, for instance — then you’ll see News results embedded into the results page.
Again, these are from a completely different source; in fact, publishers have to apply to be included in the News results. (Google has an established process and takes many sites. Yahoo! and Bing are far more restrictive.)
