Link obfuscation in SEO involves hiding links on a web page to make them less visible to search engines. This practice relies on specific coding techniques to make links less obvious within the content. Its main objective is to improve the ranking of pages whose links remain visible, by preventing link equity from being diluted to less strategic pages. Links to pages such as the contact, shipping, or returns page, which are important to users but less of a priority for SEO, can be hidden. Similarly, links pointing to less popular products can also be obfuscated.

In addition to improving link relevance, obfuscation helps strengthen the semantic coherence of the content. Although this practice primarily falls under the umbrella of organic search optimization, it can sometimes be perceived as information concealment by Google’s indexing robots. However, in practice, reasoned obfuscation is generally not considered a violation of ethical guidelines and is not subject to penalties. A common approach is to implement specific HTML coding techniques to hide links, as illustrated in a presentation dedicated to SEO optimization of the structure of a Prestashop e-commerce site.
