During the last webmaster hangout, Google employee John Mueller emphasized the importance of E-A-T for YMYL sites (sites that provide information that can affect a user’s life, health or money). The question was related to a commercial medical site.
According to Mueller, Google’s algorithms are more critical to topics related to health and medicine, which is why E-A-T signals (Expertise, Authoritativeness, Trustworthiness) are important here. It is important to make sure that the site meets high standards – it must have quality content created by experts.
Mueller also suggested reading Google’s post on Core Algorithm Updates, which includes a list of important questions for site owners. In addition, it is advisable to read the guidelines for assessors regarding the evaluation of YMYL sites. A medical e-commerce site falls into this category.
NIX Solutions emphasizes the importance of considering how the site might be perceived by assessors and make sure it links to reputable sources. It is important that the content is not only of high quality – experts in the specified field must be involved in its creation.
