Website marketers have been buying links since the dark ages. And there are legitimate uses for paid links. After all, Google has one of the largest network of paid (pay-per-click) links on the internet. But there is another seedier side of paid links. It doesn’t take long until you stumble upon paid link schemes for SEO. The purpose of these links is to manipulate search engine rankings (SERPs) for your targeted terms – ranking your web pages above competitor web pages in the search engines. This tactic has been going on almost as long as paid links themselves.
