In a nutshell, to be popular with Google, your website has to provide content relevant to specific search keywords and also to be linked to by a high number of reputable and relevant sites.
Many of the optimization techniques that are being used are legitimate, ethical and approved by Google and other search providers. This is possible because search engines give away their presence by setting a special field get rich trading options pdf files the web request that asks for content.
A cloaked page would serve the Googlebot with content that is stuffed with keywords to suggest that your site is relevant to specific search terms.
This Naked Security article explains how these attacks work. But regular visitors would see a regular page, so everything would look normal and no one would realize that there was a problem worth reporting.
The second most important part of search result manipulation is to ensure that Googlebot sees other relevant and well-ranked sites that include links to yours.

After quick inspection, we realized that someone was using cloaking techniques to poison search results, but instead of feeding fake HTML pages to the Googlebot, they were using PDFs instead. When doing a Google search for keywords found inside those PDFs we found a large amount of similar documents on a number of legitimate, but unrelated and likely compromised, websites.

Those are the links that, when followed, expose the whole link farm to the Googlebot. Many other phrases and keyword combinations within the document give us a good idea of what else we could search for. A quick analysis reveals that many three-word combinations found in the document would lead to the same PDFs when searched. But to observe what unsuspecting users would see if they clicked on what they thought was a link to a PDF document, we can simply use a web browser with developer tools.
Here is an example of the redirection chain that takes place:. Not surprisingly, the redirection involves some TDS sites Traffic Distribution Systems that pass along a unique ID of the affiliate marketer responsible for this campaign.

Just another short term black hat technique. I wonder if they did benefit from it at all. I certainly would not. I cant believe this is still possible, I used the same methods to locate, visit and retrieve a very large potion of newly active and relevent malwares before most AV labs had seen the first sample.
