The so-called prince is guilty of crime and common crimes. SEO history, a lot of famous websites, big sites in the search engine this independent kingdom, because of the tiantiao of the search engine, there have been a painful past. Is the so-called successful site SEO, are the same, the failure of the site SEO, each has its own reasons. Summing up these failed cases may give us some living lessons that are much more interesting than the articles on SEO.

First, the use of the gateway home, BMW Germany bmw.de website was brutally Google blocked

In early February 2006, the BMW German website exposed the network "cheating" scandal, was blocked. The reason for this is that, in order to promote the rankings in search, to attract more users to the home page, bmw using "SEO" technology, set up a "Gateway page." Embedded in its code is a number of "Newcars" (New Car), "usedcars" (second-hand car) and other popular search keyword references, artificially make it appear in the first few search results, but users in the browser do not see these keywords. These "gateway pages" are open only to search sites such as Google.

In fact, even now, this behavior in corporate websites, portals are also more common, many sites will be as many as possible to list a lot of keywords. Even a lot of new sites will deliberately list those hot words, such as "Sister Furong", "lead eldest brother" and so on to increase traffic.

Google Webmaster Guide/Quality Guide/Specific guide clear advice: Please do not use hidden text or hidden links.

Second, the new version to retain the old version, is considered to be copied content, batteries.com site rankings plummeted

Batteries.com is a famous American battery sales shop, 2004, the site was revised, at that time in order to avoid a large number of dead links, the site retained the old version of the page, therefore, the search engine in the index of the new page also included a large number of redundant old pages, the results of the search engine thought batteries.com Copy Web content, cheating, in addition There are also a large number of dynamic technology generated Web pages, resulting in search engine indexing difficulties, the most caused batteries.com in the search engine's natural rankings fell sharply.

Later the site with a well-known search engine marketing company, the site has been thoroughly optimized, and deleted the redundant old version of the page, 4 months later, the site was indexed by Google, the number of Web pages in the proliferation of battery-related keywords in google and Yahoo are ranked prominently.

The Google Webmaster Guide/Quality guide/Specific guide clearly states that you should not create multiple pages, subdomains, or domain names that contain a large amount of duplicate content.

Change to keep the old version, now for many sites, is also a very popular practice, a link to avoid death, the two old version of the content is a piece of history is difficult to give up. But for search engines, repeating content is rubbish, is spam. Some people think that it is wrong to continue to keep the old version after the launch of the new edition, which will definitely add more pages to the collection. If you do not delete, Google will help you delete. The feasible approach is to use the 301 ' redirect.

Third, the homepage redirects, the Hilton Hotel website PR value should return 0

Web redirection, and it must all be good. 301 Redirect is permanent Redirect, apply to the revised page, but 302 redirect is temporary redirect, useful to convert domain name, but this is the search engine does not permit method, because this will bring to cover.

Examples of the Hilton Hotel Hilton show that redirects are not used indiscriminately. Hilton Hotel has 15% of the order is brought through the site, customers through the site to book the cost of the hotel is their telephone booking cost of 1/3. Therefore, the hotel attaches great importance to the online business. But Hilton found their customer groups are too different, a site content and style is difficult to meet the characteristics of customers in all walks of life. In order to obtain more orders through the network, Hilton Hotel for different customer base, the special release of more than 50 micro subsites, different types of customers to browse the content and style of the site are different to locate more than 50 types of customer groups.

For example, for government departments and the Army of travellers dedicated to building a two-level domain name Web site: gov.hilton.com, the subsite has the government staff quotes and links to related tourism resources, such as travel allowance information. But once upon a time, the Hilton website of all the two-level domain names are automatically redirected to jump to the main station under the relevant content. such as gov.hilton.com are pointed: Http://www.hilton.com/en/hi/themes/gov/;jsessionid=DL05A2ANGF3XWCSGBIWM22QKIYFC5UUC and so on. This redirection causes these specially designed child Station homepage PR value (PageRank) is 0, but the child station content includes in the Google the quantity also to be 0.

This is actually a fake sub station, because it does not plan the content according to the structure of a stand-alone site, but simply sets up multiple subdomains and points them to a page that is not a stand-alone structure site. Once upon a time, there is a saying that the more the station, the larger the site, the more easily included. Some sites with speculative mentality, to create a large number of sub domain names in the form of an attempt to form a large number of child station illusion.

The Google Webmaster Guide/Quality guide/Specific Guide clearly states: Do not use hidden or deceptive redirects.

Four, Google blocked Hao123

Hao123 was Baidu acquisition, once a period of time, Hao123 was brutally Google blocked. A lot of comments that Google's move is against Baidu's competition, but really from the search engine Tiantiao look, Hao123 indeed irregularities.

According to the standards established by Google's crackdown on spam cheating websites, that is, how to determine whether the site is suspected of spam, mainly to see whether the site has "hidden text or hidden links", "a large number of use of content unrelated to the Web page," "Transition page", "specifically for search engine Production Bridge page", " A page or site with a large amount of duplicate content.

and the classification website such as Hao123, inevitably will appear these situations. Therefore, it is normal to be blocked by Google in accordance with spam cheating.

In addition, hao123 for the expansion of traffic, it must be based on the social hot spots continue to increase the hot links, and its own not what their actual content, mainly links, by Google's view, is a typical violation of Tiantiao.

Google Webmaster's Guide, quality Guide-specific guidelines clearly stated: Please do not create "bridge pages" specifically for search engines, or use other affiliate programs as a cliché (cookie cutter) method with little or no original content.

So far, Hao123 has only been included in Google more than 1000 pages, Baidu has included more than 5,000 pages.

Five, guests gather member website was blocked by Baidu

Customer is a classified information site, mainly to provide users with various types of life information published. I have registered members in the customer, there is a period of time, the customer gathered to launch a very attractive function "channel customization column", claiming to be "distributed e-business Model", the main station for E-commerce applications, so many small webmaster by modifying the domain name DNS way, Add almost identical classification channels to your site so that you can quickly form a column on your site. The whole station uses Div, the member can have a powerful classified information channel free, provides more than 100 customizable columns, provides more than 500,000 information database, the member can also insert own advertisement.

This business model is bound to produce a lot of duplicated content on the web. This is a very painful fact for search engines. Because search engines like the original, do not like those duplicate content. This is also a very painful thing to search for users. Therefore, the final Baidu will be the custom channel from Baidu all down.

Six, 51.com was blocked by Baidu?

51. COM, known as China's largest blog community, is the founder of the network legend Shengdong East. In the Alexa query, the site's latest ranking in 211, in Baidu, input site:51.com will find that Baidu only included 51.com a record, this is a very strange thing. Even in Google, there are only more than 30,000. Ordinarily this should be inconsistent with its rankings. So, there was a time, online rumors of Baidu blocked 51.com.

Previously, someone had studied Http://www.51.com/robots.txt's files and found that they blocked many directories:

User: *

Disallow:/404.php

Disallow:/9588.php

Disallow:/addaccesscount.php

Disallow:/addclickcount.php

Disallow:/confirmphoto.php

Disallow:/ip.php

Disallow:/jb.php

Disallow:/login.php

Disallow:/norz.php

Disallow:/rzphoto.php ... There are many, limited to space, not one to write.

But now that the file is no longer viewable, the exact reason is unknown.

Some of these cases are quoted from Dr. Feng Yingjian's "Network Marketing Basics and practices". In his book also mentioned a very interesting thing, Seo kingdom's "Shing":

In September 2005, the Wall Street Journal Online published an article in which a number of websites disappeared overnight from Google and Yahoo, which have commissioned SEO service traffic-power.com to do SEO on their sites.

This nightmare is from the mainstream search engine to delete the traffic-power.com site after the start, was traffic-power.com optimized customer site was subsequently deleted, Google deleted the site because traffic-power.com used a lot of search engines as a means of cheating (that is, search engine garbage), such as creating a stack of keyword pages, or even content unrelated to the site, and then redirected to the customer site. Traffic-power.com also links the customer's Web site to a Web site that has no real content and is flooded with links to disguise the breadth of links (link popularity) through its own link factory (link farm).

The US Consumer Protection Agency, the Commercial Services Authority, has received complaints from more than 100 websites related to this, which can be seen as large. Google's staff in their blog even deliberately reminded: customers must be the choice of their own SEO service providers to do the work of responsibility, to understand the SEO service provider is in what way to implement your site optimization.

In short, Google has Google's survival rules. But no matter what Google will be, SEO must be rational, beneficial, there is a section, is the so-called, SEO too much.
