Swap Black SEO – SEO WIKI
Swapping is the most illegal way of search engine optimization, in which the content of the page that is successfully indexed by the search engine changes.
When swapping, the user clicks on the link that is in the first lines of the output, and gets to a page that contains not at all what he expected to see.
The purpose of the swap is to profit from the sale of the reference mass. It complicates the ranking of sites and undermines the image of the World Wide Web as a whole.
Search engines identify sites whose optimizers resort to swapping, and then remove them from the database of search engines.
