The most basic situations
First, use "hidden" means to deceive search engines or users. One kind of content is submitted to the search engine and another content is displayed to the user. Nowadays, search engines are getting smarter and smarter. Don’t take chances, otherwise you will be killed by them sooner or later.
Second, fraud is done for the sake of search engine rankings. The way to judge whether your website is fraudulent is very simple: ask yourself, "What can your website give users? If there were no search engines, would you still do this?" Another way is whether you can calmly tell the user Does your competitor explain some of the things you do to your website?
Third, participate in link programs to quickly improve website ranking or PageRank. This can easily lead to penalties, especially linking to prohibited sites or "bad neighbors", which can negatively impact your site's rankings.
Fourth, use some unauthorized computer programs to submit web pages and check rankings, among which WebPosition Gold is particularly objectionable.
