Search Engines (Week 4)


How do search engines rank the stuff they find on the internet? The location and frequency of keywords. Terms appearing in HTML title tag are often assumed to be more relevant than others. 
Link Analysis: Can analyze how pages link to eachother. Search engine can determine what a page is. It is "important". Some webmasters build "artificial" links to boost rankings.
who, or what, makes one page (that you might get in your search results) more useful than another one, so that it is put at the top of your search results?what are some of your favourite search engines? why do you like one more than others?   A webpage is useful if it has the information you are after. Basic facts are given, these facts are elaborated on and sometimes links are provided to other websites based on specific information you might be after.  The information has more credibility if it is found on a professional site, without bias. Google is the best. You can find anything and I believe it finds the most relevant websites.
