This is a part of an article on a blog I read about black hat practices but I didn't understand what it meant. How can you make a website look different to every visitor that comes to your site and also ward off the crawler without getting noticed?This is probably one of the most common, and most likely to get your company banned, practices out there. Mainly a company can designate which parts of a website that Google looks at. Google then lists the website under the titles and keywords that is found in that content. The issue comes when a company shows Google content, and then makes it so viewers see different content such as ads or links to malware infected sites. This is what is known as cloaking and will get a website removed from Google in very short order.
