When search engine optimization has become a topic many techniques were used, because at the time the search engines use a much simpler algorithm. As these tricks are used to exploit the simple algorithms that also served to be more advanced. Let's look at a couple of tricks.

Concealment and redirects are methods by which you display a page with the search engine, but a different visitor. The redirection only takes visitors to a page and then redirects to another page by updating the page with everyone in his place. Cloaking involves stepping fool a search engine into thinking it's more and get step by step to send false information back to your boss.

Other techniques involve the overhead of meta tags with keywords or key words hidden in plain site on the web page. A variant of this technique is to reduce the key so that they are too small to be seen by the naked eye.

Use of unrelated keywords is another trick, especially when combined with the previous tricks. By using unrelated keywords so you can drive traffic to your site from multiple sources.
