When planning your website, divide the website into pages where each page reflects a specific topic. When a web page focuses on a specific topic, it is weighted more heavily by most search engines for that topic (or keyword/keyword phrase).
Other factors that weight the pages SEO success include content length, depth, breadth, backlinks, placement of keywords in the copy and within the XHTML and META tags to name just a few. Make sure the specific page topic is the primary part of the META page title, XHTML header title and page content (first and last paragraph).
