I am trying to understand how does Google search for content within a page. When we search a page, it displays relevant results with keywords in the title or other important places. The thing that astonishes me is that how do they grab the starting area of the text? They show a small text with the search results. How do they manage to have it as there is nothing special in a webpage that makes a Google bot understand from where does the actual content start. Please help me out. Thanks
