A case study of the Black Hat technology of SEO

Dou Peng Law (cloaking) is the SEO black Hat gimmick, webmaster will be a page with two different pages, a version to the search engine to see, a version to the user, this practice is extremely contrary to user experience standards. Search engines have said that the search engine is an ordinary visitor, should not be differentiated from ordinary users. Would you do that without a search engine?

Today, occasionally search a keyword, found to occupy the first site of Baidu is to use this technique, will do a lot of SEO optimization page to search engine crawl, and ordinary users open, in addition to the title keyword and description, only one Taobao guest of the IFRAME. Baidu's index crawled its content as a description, but I opened the page and found no such content at all.

The image above is the source that the user can see.

Open the Baidu snapshot, see this piece of mess interspersed with the keyword article, these content only search engine can crawl to, and ordinary users are not see. Such Baidu crawl page is conducive to SEO page, and users see, is only a Taobao guest of the IFRAME.

Baidu said that such a Web page if found by search engines, will delete the index of the entire station. But high risk brings high returns, there are many webmaster use opportunistic way to achieve the goal of rapid optimization. While, the Devil a battle, on the policy, there are countermeasures, there will always be someone can drill to the loophole. But if you really want to run a Web site, this kind of tricky way or not, maybe one day Baidu to do a adjustment, all the rankings are floating clouds.
