It wasn’t that long ago that link building was viewed as a mysterious dark art that involved various underhand “black hat” techniques to create backlinks to your site in order to influence search engines. At that time search engines worked on the basis that the more links you had – the more popular your site and therefore the better the content must be. As search engines have evolved and become more sophisticated, they’ve identified and discriminated against such dubious ploys.
Today, employing these types of deceptive techniques will get you demoted in search engine rankings, so doing more harm than good. That’s not to say that the search engines don’t take links into account – they do, but they have to be genuine, good quality links. Remember also that those false backlinks do nothing for your revenue – they don’t encourage prospects or convert leads, whereas quality links from good sources will; as well as increasing your standing with the search engines.
