It is clear that search engine spiders are very intelligent, in the process of crawling the Web page can be recognized annotation information, directly ignored, so the annotation content is not crawled, and will not participate in the analysis of the content of the Web page. Imagine if spiders could crawl annotations, and this annotation code is equivalent to a hidden text, then the main content of the Web site can be called through JS Code, only for users to browse, and the content of the spider to crawl is placed in a large number of annotation information, so that the Web page to show spiders and users is not the same content, If you are a gray industry station, then you can give search engine a completely formal content to show, escape the shackles of search engines, the search engine will officially allow you to cheat?
