Understanding the Impact of the August 1, 2018 Google Algorithm Update on YMYL Websites
In the ever-evolving landscape of search engine optimization (SEO), Google’s algorithm updates consistently shape how websites rank and how businesses establish their online authority. One such significant update occurred on August 1, 2018, and its effects were particularly pronounced among YMYL sites—websites that deal with topics impacting users’ financial stability, health, safety, or overall well-being.
Overview of the August 2018 Update
According to SEO expert Marie Haynes, this update primarily targeted Websites in niches related to health, nutrition, and medical devices. Notably, many large players in these sectors experienced substantial declines in search rankings, while smaller, locally-focused businesses often benefited by gaining visibility. This shift indicated Google’s increasing emphasis on assessing the credibility and trustworthiness of websites, especially for content classified as Your Money or Your Life (YMYL).
Google’s Focus on Expertise, Authoritativeness, and Trustworthiness (E-A-T)
Central to the impact of this update was Google’s enhanced ability to evaluate E-A-T signals—criteria that determine a website’s reputation and reliability. The emphasis on the T (Trustworthiness) in particular appeared to grow, underscoring Google’s intent to prioritize sources that demonstrate genuine expertise and reliability.
Strategies to Align with Google’s Preferences Post-Update
For website owners, adapting to these changes involves demonstrating strong E-A-T across your digital presence. Here are recommended approaches:
- Showcase Your E-A-T Prominently
Ensure your website clearly communicates your authority. Your About page should highlight awards, press mentions, years of experience, and industry recognition that position your business as an authoritative source within your niche.
- Highlight Author Expertise
Every published article should feature an author byline linked to a detailed author bio. These bios should emphasize the author’s credentials, experience, and authority to bolster content credibility.
- Enhance Business and Author Reputation
Building trust may involve securing positive press coverage, encouraging genuine user reviews, and displaying testimonials prominently. Differentiating between paid or superficial endorsements and authentic, earned recognition is vital—Google can often discern between the two.
- Conduct Product and Service Audits
If your offerings receive negative feedback or reviews, it’s crucial to address these concerns head-on. Improving product quality and customer satisfaction not only benefits your reputation but also signals trustworthiness to search engines.
- Strengthen Product-Related E-A-T
For e-commerce or product-focused sites, fostering reviews, facilitating discussions, and ensuring your products truly meet customer needs can amplify perceived E-A-T. An excellent product that generates buzz and user engagement naturally enhances your site’s authority.
Conclusion
The August 2018 Google update underscored the importance of credibility, authority, and trust in ranking algorithms—especially for sites in sensitive industries like health and finance. By proactively demonstrating expertise, maintaining high-quality content, and cultivating a trustworthy reputation, website owners can better position themselves in search results and withstand the fluctuations caused by such algorithm changes.
Staying informed and adapting your SEO strategies accordingly ensures your website remains authoritative and competitive in an increasingly trust-centric digital environment.
