The history of search engine optimization
Search engine optimization (SEO) is not a sudden a technical, but the simultaneous development and search engine up, although the relationship between the two can not be said to be "spear and shield" of the relationship, but be sure because it makes SEO search engine technology to become more perfect.
Birth and the birth of SEO Yahoo
A 1994-1997: Yahoo the birth and the birth of SEO, in July 1994, Lucos launched a search robot based on data discovery technology, and to support the amount of search results relevance ranking, it can be the first to use the Web search engine automatically Abstract.
The end of 1995, Alta Vista launch, because it has a lot of new search capabilities, by the public praise, Alta Vista is the first to support natural language search, with a web-based content analysis, intelligent processing capacity, the first realization of advanced search syntax search engine (such as AND, OR, NOR, etc.), while searching the contents of a newsgroup, but also search for images.
This stage is also the yahoo early stages of development, most people are not familiar with the search this time, it is not aware of the search engine thing, but for yahoo, most of you have some understanding on the Yahoo search site . So, will your site to Yahoo is necessary at this stage, if your site has a basic look, there are certain to be seen, general as long as the submission to the Yahoo address, within 72 hours will be able to appear in the Yahoo Directory on. Yahoo's Web site for all artificial classification, the general site in alphabetical order, the natural starting with "A" site routed to the beginning of the "B" in front, and there are two A's website, came in with A and B site in front of, for example, American Airlines Web site not only ranked in front of Bank of America, but also came in front of American Basketball Association. Therefore, a large number of sites to be named to the pursuit of A-. This is the prototype of the search engine optimization. The logic and the Yellow Pages telephone number as the ranking logic.
At this stage, Yahoo's editor of the Internet are also actively search for new sites, to enrich their databases, and their searches are artificial, the most typical way is to link from one site to visit another site. Encounter a good site, they give the main station e-mail, please stop the main registry, and are free of charge.
Yahoo editors visit these acts and we see today is the search engine spiders and robots in the form of the same tireless. There is so concerned about your Yahoo web site editor, anxious than you login to your site, and do not accept the article, this can not be imagined today. Your website Once logged in, you can always change your login information, generally 72 hours to get updated.
It is worth mentioning that, although very few Chinese Web site during this period, and most of the United States and in Taiwan, the Chinese web sites, but Yahoo is clearly noted that the future of the Chinese Web site, and quickly have a Chinese translation of "Yahoo", and This not only because of its founders, Jerry Yang.
SEO is the prototype of this phase period. Online and offline there are some papers to discuss the corresponding text, data mining and search engine programmer interviews. Web content that people initially have to comply with the principle of the search engine database, fuzzy consciousness. Similarly, the sites included into the search engine is also very easy and you use the page as long as a certain density of keywords on the search engines easily arranged on the.
It is worth mentioning that the first search engine InfoSeek be updated daily. Eight in the morning to submit your site to be included in the afternoon the next day being able to appear in the search. Because so fast and so easy to update your submission to the large number of stations was another way the Lord began to change frequently log on a different site, in English the word to describe the emergence Spam is not responsible for the main stations to manufacture the proliferation of spam, and soon these search engine too much.
So, SEO from the start Heibailiangdao began. White, the English language is a white-hat, is able to realize the search engine in accordance with the principle to rationalize their own websites, so that your search engine and get good exposure. Underworld, the English called black-hat, as if such optimization were hackers, looking for weaknesses in the search engine, trying to confuse the message strongly upon their search engine, so as to increase the real site exposure.
During this period, because of the powerful lure of profit, adult sites can be said to lead to "black" search engine. So SEO and search engine from the beginning the relationship between love and hate, this time, charges of website optimization services also began to appear in the United States.
In the Chinese search engine field, China is not late to start. August 1996 is the earliest established in Sohu's management information to do a similar classification of Yahoo's site navigation, once a "go out looking for maps, surf the Internet and Sohu" in the world.
This time, no one is in a Stanford University dorm room, the two brightest students are attracted worldwide attention gradually nurture a new search engine. They invented a new theory called PageRank, to re-create the search engine. The new search engine is now Google.
Google SEO theory of emergence and the emergence of
II ,1998-1999 Year: this stage, the U.S. Internet Conference started having some articles published on the website optimization. These articles began to pay attention to the link popularity (Link Popularity), List Web Links (Directory Listing) significance. During this time, search engines also know the need to limit people to submit sites to prevent the proliferation of spam, then began to fight back.
Start with a large-scale discounting Alta Vista "to optimize our" or "Let's promote" this type of text pages. SEO practitioners began to realize the principle of the search engine to break more and more difficult. In 1999, a website promoted to the top ten than on hard times in 1998. Search engines began to pay more attention to the significance of link popularity.
Google in 1998 also received the first of thousands of dollars in venture capital, moved out of the Stanford campus, officially named Google, a domain name from google.stanford. Edu into google. Com. This new search engine for the first time to measure the importance of the site link popularity as a ranking criteria.
May 1999, the British launched ALLTheWeb FAST search engine. Web search can make use of its automatic classification ODP to support Flash and PDF file search, multi-language search, it also provides news search, image search, video, MP3 and FTP search, has an extremely powerful advanced search features. Such powerful features make it one of the most popular search engines.
The early stages of this phase, search engines have begun the process of diversification, began setting up a multilingual website, such as Alta Vista to start the first Latin version. Professor Wu Sheng Chung Cheng University, Taiwan, led by GAIS Lab in January 1998 created the OpenFind Chinese search engine. It was the first development of the Chinese intelligent search engine, known to most of the pages and grab the world began to enter English search engine.
Google in 1999 received two thousand five million of funds to begin full development, and has handled 50 million times in the media, search, Google again, this investment also moved to San Francisco - Palo Alto, Silicon Valley than the city. Google also began to meet partners soon from AOL to Netscape, Google once again moved to the current global headquarters remain in San Francisco - Silicon Valley, called the Mountain View city. At this time began to try to control the search engine marketing, advertising extensively in search engines. This caused resentment of many searchers, because everyone is still in use 56KB modem Internet access, a large number of ads that slow Web page appears.
Google searches found the pace of the deadly impact of this problem. Simple web design so that all fresh and new, even more so the search speed quickly Lord excitedly spread the news in various stations, each station on the main forums are full of Google's excellent assessment after another magazine interview is to be recommended on Google, Google's overall performance of the formal stage.
The emergence of search engine Baidu and innovation
Since 2000, logging a site to search engines is getting longer and longer time spent. Search Engine interested in fee-based services, a new search engine from Inktomi to the Alta Vista are infected with the money. At the same time, searchers hope to have a search engine can really give them useful information. Google does not live up to people's expectations, it began to consolidate its exact search in the search engine position.
First out is InfoSeek, the InfoSeek bought by Disney in 1998, became Go. Com. Since then, InfoSeek abandoned, and Go. Com also uses Yahoo search to replace. In 1999, InfoSeek, a Chinese engineer left the search engines towards Beijing, he sought to create a "Chinese people" search engine, and by an ancient Chinese word "no trace of her thousands of Baidu, when I look back , that person is in the dim light, "the inspired, the Chinese search engine named" Baidu. " The engineer is the founder of Baidu - Li.
Li himself is a new generation of search technology expert, he had solved in 1996, how to sort the quality of web-based relevance ranking based on the perfect combination of issues, and granted a U.S. patent. Silicon Valley search engine Baidu's talent combined with elite, relying on Beijing's best software talent to develop a large commercial Chinese search engine, Chinese and English search search from the same starting line stand at the same time, Baidu search cleverly solved the data update bottleneck, the entire database of Chinese web pages can be updated once per day fastest.
2000 is also a Flash animation, JavaScript and dynamic effects Rollover popular images of the year. People love these dynamic forms, but few people know, search engines can not understand these, search engines can only read the text, rather than the creativity of these senses, as they have been read the way people in the simulation, but it can not simulate the human perception, even today, search engines do not solve this problem.
Starting this year, in fact, submitted to the search engines do not need a new site in the search engine under the previous pages as to fill "ADD URL", the search engine from an existing Web site has been found on the link to the new site access and inclusion. At this time, SEO practitioners have begun to know if the site can be directory navigation station (Directory), especially the Open Directory ODP (Open Directory Project) included, will contribute to enhance the search rankings. ODP is the best known DMOZ (www. dmoz. Org), the crown by Nick Adams River • Bob • Tours two Sun engineers in the company founded in 1998, it is an artificial classification of sites to your directory website. At this point, it is the same composition and Yahoo.
The difference is, it is the main station by the world to do their own editing to maintain, and Yahoo is by professional editors to maintain. About DMOZ, popular search engines DMOZ, through manual analysis because of the credibility of the site will naturally be higher than the search engine spiders and robots to get the site information is reliable.
Log in much the charges in 2001 fire. Search engine market through cleansing, people began to abandon the search engine Hotbot, Alta Vista and Excite. Google Alta Vista trying to emulate the way back to narrow the version of the search engine, but this is painfully dying failed, and in 2003 acquired by Yahoo. Inktomi also lost several application partners, a sharp decline in 2004, also acquired by Yahoo, and Yahoo search has become the main focus of today's technology.
IV ,2002-2007: Google Dance and the sleepless nights SEO
In fact, in 2001, the sensitivity of the station owners and SEO practitioners feel that a phenomenon never seen before. Some people on the site's ranking in Google disappear overnight, but some sites are ranked first. This phenomenon is almost once a month. Later, people know, this is Google regularly updates its index (Index) of the distance events, feels like dancing, like SEO practitioners are therefore known as the Google Dance.
It is because of the Google Dance, every SEO practitioners are staying up late the night that Google updated look at the possibility of their Google SEO to achieve results. Each update has winners and losers, there are always thousands of online SEO forums discussion can be expected to know what the next update can be expected, or guess the exact date updated.
At this stage, the search engine face more serious flooding problems. SEO practitioners extensive use of the portal page (Doorway Page), repeat site (Duplicate Website), camouflage website (Cloaked Page), hidden links (Hidden Links), etc. to try to cheat Google. In addition, DMOZ is Google as an important channel for your new website, DMOZ has been injected into a lot of spam.
SEO in 2002 is a lot of abuse for one year. However, search engines and SEO from the struggle against the illegal practice of discrimination continue to enrich their own technology, your refusal to seize the site has been included in the grant excluded. But the blockade has wronged a lot of honest SEO site.
In China, Baidu began in September 2001 to provide public search services, and successfully so that Sohu and Sina to start using its search technology. It also provides news search service, rapidly expanding user base.
In 2003, more and more the application of site design in Flash with caution. This year is also a search engine to counter the proliferation of garbage a year. Many practitioners understand that Black Hat SEO techniques (black-hat) is not feasible, but to truly improve the site, solid quality.
Google in 2003, is squeezed out of the Alta Vista and Inktomi, to become dominant. Google search engine was born in a confused era, in that era, such as Alta Vista search engine market share of their confidence was too lazy to change. Google SEO by individual practitioners to promote station owners to come from behind in one fell swoop. Now, Google began to fight back spam flood, it directed against those who have supported it to the owners of these stations SEO practitioners. These people became the victim of the success of Google.
2003, Google's "Florida Update" (Florida Update) really let the station master was exposed all over the world Google's powerful. If a strong hurricane General, Florida Update site overnight to thousands of disappears from the search or the past ten blown 100 pages later. This occurred in the Nov. 16 update, especially in the upcoming Christmas hopes to earn a hard e-commerce sites with heavy losses. From now on view, Google's spam this update is back and unlawful acts of a major battle in SEO.
However, due to the use of filters (filter) is not perfect, the impact of a lot of innocent sites. Was called "Florida Update" because this update from the Google data center in Florida began.
Later, in January 2004 called "Austin Update" of the aftermath is also the site of considerable impact. All of a sudden, so SEO practitioners have suddenly morphed into a Google Adwords expert, we can not rely on Google ads to keep this holiday season sales.
Google on the two historic renovation, a lot of SEO practitioners to a large lesson. Neatly from the quality improvement of the site itself and not opportunistic, as the only feasible way to SEO. PPC is also stable as an important means of marketing strategy, and SEO search engine marketing has become (SEM) part.
Yahoo and Google at this time decided to officially parted ways. For a long time, in order to compensate for his lack of your site is indexed by the artificial, Yahoo has been using Google's technology to provide Web search. Yahoo shows gradually acquired Alta Vista, AllTheWeb and Inktomi Corporation, people aware of Yahoo's mood - whether it is indirectly raised by Google? It's hands still 20% Google's shares! Finally, in February 16, 2004, Yahoo sold Google shares, formally bid farewell to Google, the search engine onto their own path of development.
In the same year, September 12, 2004, Google launched Simplified and Traditional Chinese versions of two search engines.
Into 2005, the biggest change is no longer a regular Google Update activity, but gradually become daily progressive update. Not see dramatic changes. SEO practitioners can quickly see their efforts if there are results. The discipline to follow the search engine, a reasonable way to adjust and improve the structure and content of the site, the only way to ensure site stability. More importantly, follow the standard operation of these sites are optimized not only a good ranking on Google, Yahoo and MSN will also also have a good result. Chinese Web site, if a solid job in the quality of the site will also benefit from the ranking in Baidu.
