Swapping term explained
Swapping or search engine spam is a method of SEO in which content is already indexed page is replaced by other content. As a result, making a request, and clicking on the found link, the user encounters a completely different content – optimizer needed, not for user.
The main goal of the optimizer is: earn as much money as possible on the links. Therefore, the content of the page after applying the swapping can be a completely useless for the user text. Example of the application of the swap. The optimizer spins and then pushes the top of the search engine of any website or an individual page with an interesting topic for visitors. Without changing the title of the site, the optimizer removes it completely or partially old content and fills revenue-generating links (the higher the site is located in the top of the search engine, the big money gets the master at posting links).
