Website privacy policies are used to inform consumers of the use and processing of their data but are often long and jargonised, complicating the comprehension of the website's privacy policies. While consumers require assurance on the processing of their personal information, organisations must also ensure that their website privacy policies cover the principles of data protection Acts. In South Africa, the Protection of Personal Information Act (POPIA) came into effect in July 2021, which provided principles for processing personal information. This study adopts the PRISMA methodology to systematically examine the existing literature to propose consolidated guidelines to aid website developers and administrators in drafting website privacy policies for the e-commerce sector. The proposed guidelines are a holistic consolidation of literature that applies to various jurisdictions. As the study was conducted in South Africa, the guidelines were also mapped to POPIA, and a sample of website privacy policies in South Africa were reviewed using the proposed guidelines. The e-commerce industry can benefit by implementing recommendations to aid them in addressing data privacy principles in website privacy policies.
