Now Google will show more sitelinks in the search results, so that the visitors can go directly to the useful pages of that top site. Google announced that it is becoming very popular to the visitors and for this reason they have decided to show eight sitelinks instead or four. They have changed their algorithms to fulfill this purpose. According to Google, eight sitelinks will give a good overview of that particular top site’s content and will also help the visitors to access more topic or areas of the top site.
