Today when I searched a site with Google, then it showed some results and many of them were with:Show more results from www.google.com. What's the function on SEO? and is it useful for our site?
Google has been done some changes to this function from the last years. Initially it has the simple HTML link to a site command feature and then changed it to showing more results withing the same page and now again it is showing a mix of the two by sometimes redirecting to the site command feature when clicked on More results or displaying the more results within the same page. However, you will see this option with the most famous sites that are been regularly crawled by Google bots.
