Titanium Media Note: This generation of people can be said to be accompanied by the growth of China's internet grew. How have they experienced the development of the Internet industry? What do they think? Titanium media writer White Rat Nest launched "The Internet Growth" series of articles in the Titanium Media Exclusive (link address: HTTP://WWW.TMTPOST.COM/AUTHOR/BAISHUWO), this article is the nineth: The last one talked about the hospital enthusiasm seo this thing, And this is related to the existence of search engines, this article on the Peace search engine related to some things. When I start to get online, how to find the information you need is a big problem. You know there are a lot of things online, but you don't know where it is. Then the great search engine can save you in dire straits. As I said before, when I first started surfing the internet, I browsed the internet mainly through hyperlinks on the portal site (that is, clicking on a text or picture that would jump to another page). Hyperlinks are really simple but incredibly useful inventions on the internet. Thousands of pages are interconnected via hyperlinks. Through different organizations, people can better browse content, find relevant content, link ads can also be used to realize and so on. However, hyperlinks also have a lot of limitations, if you are only in a relatively centralized site browsing, then hyperlinks can give you good guidance. But if you want to find the relevant content on the vast internet, simple hyperlinks seem to be powerless. When you've made 10 jumps from a page and haven't found the relevant content, you're not going to have the patience to keep looking. The emergence of search engines help people solve the problem of positioning on the Internet. Through the search engine, only the corresponding keywords, you can easily early related to the content, and do not need to go through seemingly endless hyperlinks to navigate the first layer of the walk. Of course, search engine is not isolated existence, can make search engine existence Foundation is the existence of hyperlink. Search engines can complete the most important two core elements-information capture and information sequencing, are inseparable from hyperlinks. Search engines rely on a program called "Reptiles" (spider) to get information on the Internet. It is called a "reptile" because the program will "crawl" along the hyperlinks it obtains, it is because of the interoperability of Internet hyperlinks, from some large sites or some important navigation station (directory station), the crawler may through these thousands of links throughout the Internet. Search engine crawler When "crawl" to the corresponding site, it will save the site to its own database in order to search for sorting. In other words, to achieve real search, search engine manufacturers need to put almost the entire Internet into their own servers. To store this data, search engine companies need to have a large number of servers. Zhou, a former Google technology director at a meeting in 2008, had revealed the level of servers GOOGL owned, saying that "the number of Google servicesAbout the equivalent of America's third-largest PC maker. "Although we do not know the specific data, we can look at Google's data center on the other side of the size, according to Google released data show that Google's global energy consumption reaches 260 million watts, which is equivalent to all the electricity consumed by home users in the Virginia State capital, Richmond, or Irvine, Calif., or equivalent to a standard nuclear power station's 1/4 output power. Most data reports suggest that Google is the world's largest enterprise with servers. Of course, just storing the data is far from enough, and the purpose of the search is to find the page that best fits the user's needs. The search engine then needs to sort the different pages, and the basis of this sort is calculated by hyperlinks. In simple terms, the search engine's sort base algorithm is this: most pages have hyperlinks to it, or it links to others, and this link can be considered a vote for the quality of each page on other pages. Search engines believe that if there is a large number of links to a page, the page is popular, it should be in front of the search. Conversely, sites that are not linked are unwelcome. Of course, the search engine will also consider the keyword matching degree, linked to the quality of the page itself, and many other factors, but in general its work is the above mentioned. It is because the work of search engines is implemented through hyperlinks, you can understand why most websites like to exchange links. Because the increase in the link between each other can improve the site in search engine rankings. Of course, if you do not have so many "friends", you can also find a lot of people on the internet to sell "friend Chain", they will be very "friendly" to tell you the price of each link. Direct selling links is a relatively rudimentary approach. Because even if there is a link, but how the effect is difficult to measure. After the search engine dominates the internet, there is a special type of work--seo (search engine optimization). SEO responsibility is to let the site rankings in search engines as far as possible, so that your site may be with many people to visit. As mentioned in the previous article, many websites will have special SEO staff to optimize their site rankings. Around search engines, there are a number of related upstream and downstream industries. It's not going to be the same here. When you know the general workings of a search engine, you can probably understand what these professions are all about. Back to the search engine itself, as mentioned above, to the thousands of billions of data to quickly find the required pages and complete the sorting, this is not an easy thing to do, the scheduling of tens of thousands of machines resources is not easy, including Microsoft, Yahoo and other companies have been in the search engine has been tumbling. Search engines in infrastructure investment and technology barriers can be said to be a very high threshold, but at the same time the search engine has a fascinating profit model, which allows many companies are flocking to the engine business.
