The cunning Internet entrepreneurs who Constantly try to manipulate Google’s Search engine
For the millions of Web sites without a well-known domain name, those rankings can mean the difference between success or failure because Google's search engine drives so much of the Internet's traffic, With so much at stake, low-ranked Web sites spend' much time and money trying to elevate their standing, even if they must resort to deception. The tactics include "keyword stuffing"--filling a Web page with phrases associated with a specific topic such as "laptop computers" in hopes of duping the search engine;
It's a risky strategy because Google and other search engines penalize Web sites that get caught unnecessarily repeating the same word. In the worst cases, the offending Web sites are deleted from the index so they don't show up in search results at all.
Sometimes webmasters act secretly to populated their sites with a large number of incoming links from other sites. This approach makes a site appear more authoritative and popular than it really is and thus rise in rankings.
Such dirty tricks pollute the search results with Web sites that have little to do with a user's request, frustrating consumers, diminishing Google's credibility and threatening to undermine the company's profits by driving users to its rivals.
Not surprisingly, Google works hard to prevent the mischief makers, who sometimes are branded as "Black Hats" because of their dishonest practice, from filling the websites with useless contents. However, Google knows it can't entirely avoid Black Hats. So, webmasters searching for secrets are better off looking elsewhere. Everything you ever wanted to know from Google is right there on the forums that the webmasters run. There is a lot of truth in there, but there's also a lot of crazy stuff. You just can't tell them which is which.
