BLACK HAT SEOSEO MASTER

What is a hidden page in Black Hat SEO?

However, depending on the IP, different content is returned, and sometimes it is not cheating. So the line between the two is often vague. The Google webmaster blog posted a message two days ago, with a clear definition of the four situations. The following half translation, half comment.

Geolocation

Return different location-specific content based on the user’s geographic location. The location may be the IP address of the access, the cookie stored on the user’s computer, or the address provided by the registered user. For example, a football website, if an address already provided by a user has been registered in Beijing, when the user visits the website, it returns content that is more suitable for Beijing users, and more reports on the results of the Beijing team.

IP Delivery

 to translate accurately, let’s call it IP transfer.

IP delivery is one of the geolocation described above. Because the IP addresses are all assigned to ISPs in different regions, according to the IP address of the sending access request, the geographical location of the user can be determined, and then the corresponding content is returned.

IP delivery is just a technical means of returning more appropriate content, not necessarily cheating. As the example above shows, an unregistered visitor comes to the website. The server detects the user’s IP address and finds that the viewer is from Beijing. It can return content different from the viewers from Shanghai. Not only is it cheating, but it is more user-friendly.

What is a hidden webpage Cloaking

This is cheating. Refers to a set of optimized content returned by a search engine spider when accessed, while another user returns another set of content when accessed. The method of identifying whether it is a search engine spider includes reading a user agent accessing the browser or judging by an IP address, because the IP address belongs to which ISP or a large network company can be detected. This is why hidden web pages are often confused with IP delivery.

First click for free First Click Free

There are some news website content that are charged, but they are expected to be included in search engines. Google provides a first-click free mechanism, which means that users can use Google search results to come to such a paid website. On the first click, users can see the normal content, which is what Google spiders crawl. However, the second click of the same user will not see the news content, but will be required to log in or pay.

Comparing IP delivery and hidden pages, you know that IP delivery is normal, and hiding pages is cheating. What search engines require is not to allow IP delivery, but to not specifically treat search engine spiders. Suppose the search engine spider is from the New York data centre. The content returned by the website should be what the average user from New York sees, and should not return a set of ordinary content that can’t be seen from anywhere. Only search engine spiders. To see the content.

Hidden pages are actually quite dangerous black hat SEO techniques. For example, if you don’t know that it belongs to Google’s IP address, you can make the same access request as a normal browser, crawl the page, and compare the content you crawled with the content captured by normal spiders from the same geographic location to know if it exists. Cloaking.
