Some time ago, Ningbo SEO's daily post briefly explained some Baidu cheating methods of the "brushing" type (authored "Baidu cheating collection: the world created by "brushing"). Today I will also share some ways to use js scripts to achieve Baidu cheating. JavaScript, which emerged in the 1990s, has greatly enriched the dynamic functions and elements of web pages. However, black hat SEO also takes advantage of the shortcomings of search engines' imperfect JS recognition and uses a large number of JS to cheat. Today Gu Jun will also give examples of two popular js cheats nowadays.
JS cheat 1: Selling dog meat over someone else’s head
The method of cheating has been around for a long time, and many cheaters enjoy it (as shown in Figure 1). The basic principle is to divide the website into three parts: the first part uses JS to call the large advertising image with Taoke link or the corporate product image with Business Link link through the header of the web page to guide users entering from the search engine. Click (these contents are provided for web viewers.) The second part: is a large blank page. Its purpose is to give web viewers the illusion that the web page has been loaded, and no page pull-down is performed. The third part: It is "deliberately" provided for search engines to provide garbage collection content with no quality and readability for use as website updates. Through my own investigation, Google has a better identification mechanism for this method, but Baidu has tried and tested it repeatedly, and it can still be seen in the homepage rankings of many Taoke projects and hot violent industries.
JS cheat 2: Build a plank road to cross Chencang secretly
This method is for hidden text and links in websites. Many black hat SEO methods are used to change friend links or hackers invade websites to hang black links. It is difficult to use search engines to crawl JS. JS further splits the CSS ID, thereby increasing the difficulty for search engines to identify the hidden link. However, this cheating method is also mentioned in the Google Search Engine Optimization Guide. Will be punished by Google, which can still be seen from time to time in Baidu optimization cases. Specific examples
<div id="test">
<dl>
<dd> <a href=" http://www.exmple.com">For example 1</a></dd>
<dd> <a href=" http://www.exmple.com">For example 2</a></dd>
</dl>
</div>
<scripttype="text/javascript">document.getElementByIdx_x_x("t"+"e"+"s"+"t").style.display='none';</script>
Everything has two sides. Arsenic can kill people, but it can also be a good medicine to save people. JS can also block unimportant content. Properly used to reduce page code and web page size, it is also a powerful SEO tool. With the continuous development and progress of search engines, the recognition of various js technologies will also be enhanced, and many js cheating methods will be abandoned one by one. Let me quote the famous saying of Baidu’s anti-cheating team: I hope all webmasters will look to the long-term future and not be fooled by the petty profits in front of them. Focus on its own content and brand building, and develop more profit models for healthy development.
