[Homework]【整理】2011-10-23&10-29 搜索引擎优化

this is search engine optimization explained by common craft. imagine for a minute about you are a librarian. but not a normal one, you are a librarian for every book in the world. people depend on you everyday to find the exact book they need. how do you do it? you need a system, you need to know what is inside every book and how book related to each other. you system needs to take in a lot of information and spell out the best answer for the patient's question. it is not an easy job. search engine like google and bing are the librarian of the internet. they are systems collecting information about every page on the web. so they can help people find exactly  what they are looking for. and every search engine has a secret retherpy, calling algorithm  turning all the information into useful search result. now if you own a website, search result matter. when your pages have high ranking, they help more people find you. the key to high rankings is making sure your websites has the ingredients search engine needs for their rethepies. this is called search engine optimization or SEO. as it turns out, most of the big ingredients know. let's take a look, first, word matters. search engines account for every word on the web. this way, when someone search for shoerapair, the search engine can narrow the result to only pages that is about those words. second, title matters, each page on the web has an official title. you may not ever see it, because it is in the code, search engine pays a lot of attention to page titles because they often summarize a page like a book title. third, links between websites matters, when one web pages links to another, it is usually a recommendation. telling readers, this site has good information. a website that has a lot of links coming to it can look good to search engine. but some people try to fool the search engine by creating all buying bogus links all over the web that point to their own web site. usually search engine can detect when a site has a lot of them, and account for it by giving link from the trustful site more weight in the rethepy. fourth, the words that used in links matter too. if you page says amazone has a lot of books, the word book is linked, the search engine can establish that amazone.com is related to the word books. this way, when someone search for books, that site would rank well. lastly, search engine cares about reputation, site with consistent record of fresh and engaging content including numbers of quality links, maybe considered as rising stars and do well in search engine. these are just the basics, the rethepies are refined and changed all the time. good as you, is about to making sure your website has great content that support by the ingredients the search engine needs for their rethepies.
