Recently Fuqing SEO see a lot of Web sites using black Hat technology, mainly using spiders can not be very good to identify JS files and loopholes.

JS full name JavaScript, is a computer scripting language, mainly in the browser client interpretation execution, JavaScript language can be embedded in the HTML file, can be used to respond to user demand events without any network to transmit data back and forth. So when a user enters data, it can be handled directly by the client application. Interested friends can refer to Baidu Encyclopedia interpretation.

Fuqing SEO see a company in Shanghai to use JS file encryption, made a high-level hidden technology, so that spiders and visitors to see the page is different, mainly to do hidden links and hanging black chain. I see a lot of Web sites, including some government sites have been this way hung on the black chain, I hope the site can strengthen security management efforts!

Baidu Google search engine can now identify in the HTML of the JS jump code, relatively speaking, Google's ability to identify more powerful, but for file calls JS way Google and Baidu processing analysis capacity is to be improved.

Logically speaking, by virtue of search engine powerful operation mechanism can be used to identify the JS, but the search engine generally is not willing to crawl analysis JS, because most of the JS script programming language, a lot of JS file loop function, the spider may be in the dead loop after entering the state and out, so that the resources will cause huge waste And for the encryption of JS, we artificially analyze all the time, not to mention spiders?!

Recently also saw a cheat method is through the JS file to determine whether to enter the site is a visitor or spider. If you click on the site through the search results, it will be jump into the target site set by the other side, if you enter the address bar directly in the URL, then enter the site is the original face.

If you are interested in legitimate research friends can leave a message on the SEO blog leaving contact, the author is willing to share with you the encryption JS and the decision of the visitors and spiders JS files.

Google and Baidu search engine official documents have mentioned that do not recommend the site to use JS,JS will interfere with the search engine normal crawl Web pages, and cheating is the way to curry favor with the search engine, The JS package to the. js file inside, so that the search engine feel that the site is normal processing or filtering some useless information, it will not cause the search engine suspicion.

But Fuqing SEO blog is always advocated to do white hat seo, for black hat, cheating is repugnant, and I also believe that in the near future, search engines will be able to set up a fight against black hat SEO technology mechanism, the maintenance of the Internet fair, but also the Internet a Pure Land!
