Le spamdexingalso known as abusive referencing, refers to all practices aimed at artificially manipulating search engine algorithms, such as Google to improve a site's ranking in their results.

These dishonest techniques are generally used to deceive users by luring them to websites of poor quality or unrelated to their initial search.


Understanding spamdexing and its objectives

Spamdexing consists of exploiting search engine loopholes to achieve higher rankings.

People who use these methods are generally looking to generate traffic to their site, monetise their content or damage the reputation of other competing sites.

  • The use of irrelevant or off-topic keyword lists

However, it is important to note that today's search engines are able to detect these practices and penalise sites that use them.


Le cloaking is a spamdexing technique that involves tricking search engine algorithms by presenting content that is different from that displayed to Internet users. The aim of this practice is generally to optimise a site's ranking on certain queries without providing users with the corresponding quality information. Cloaking can be carried out in different ways:

  • Redirect to a different page for indexing robots
  • Use of technologies JavaScript to dynamically manipulate the DOM

Like keyword stuffing, cloaking is strongly discouraged as it is penalised by search engines.

  • Massive fan buying and followers on platforms such as Facebook, Twitter and Instagram
