Because the opportunity is rare, apart immediately point into the website want to see use what spam method ... I thought it was just a simple keyword overlay spam, but not simple ...

Into the site, originally only the latest news, all the headlines and the text is full of "unrelated words", look at the original code, nor like a special search engine optimization, many tag descriptions have not been written, but simply with the company name and some basic picture Alt key, even the first half of the use, Maybe just on the Web site, and the content is only temporarily lost some junk word test. The latest news in a large number of keyword superposition search engine is to crawl this paragraph, and then, check out the number of this site, there are more than 900!

This kind of hidden link, seo drink a post Chen Xiaohuan, or first read, the market on the SEO books, read four or five, also did not introduce, but this is the most simple black hat technique. Do not talk about the keyword superposition of spam, this use of other people's Web site for Black Hat-style link means, because it is not to their own site modification, so the probability of their own garbage is low, but if the site is K-drop, it is also very easy to affect their ranking.

But there is a small drawback to this black hat technique, which is that it does not get the connection between the anchor text. Finally, SEO drink remind everyone, although the use of Black hat SEO can make the site rankings in a short time quickly climbed, but can not be long, want to do SEO or do from the site content, structural optimization, pay attention to search engine friendly seoer is good.
