What Kinds of Websites Were Impacted by the March 2025 Core Update
Once the March 2025 Core Update rollout was complete, SEO professionals observed a range of fluctuations in search rankings. More often, as with core updates, some sites benefited and others lost ranking. Let’s dive deeper into how various types of websites were impacted.
Websites with Authoritative, Relevant Quality Content
Websites that prioritised meaningful, informative content were the ones that benefited most from the changes in rankings. These sites were usually well researched, offered comprehensive coverage of subjects and were incredibly knowledgeable about the industries they occupied.
For instance, websites in the health niche that provided evidence-based information or financial blogs that offered trustworthy advice, or educational sites that provided useful resources all benefited in terms of their rankings.
Top e-Commerce websites with a bad user experience
The update hit e-commerce sites with slow page load times, no mobile optimization, or confusing navigation particularly hard. As the focus shifted, sites that provided a poor transition for users, slower loading times or a less engaging experience would rank lower and lower.
Such websites are advised to work towards increasing their site speed, minimizing cart abandonment, and optimizing for mobile devices to prevent future drops in rankings.
Thin or Outdated Content Sites
Many of the significant ranking declines after the March 2025 Core Update were felt by websites that had low-quality, thin, or outdated content. Google’s increased emphasis on content relevance and E-A-T meant that sites with poorly written or half-baked articles, especially in sensitive industries like healthcare or finance, found their visibility diminished.
Websites that had not refreshed their content in quite some time were also adversely affected. Google’s algorithms still favor new, relevant content that adds real value for users.
News Websites and Blogs
Following the update some news outlets and blogs had mixed results. The sites that emphasizing timely, well-researched articles, and that offered authoritative coverage of subjects, benefited. But sites with sensational headlines, clickbait tactics and grammatically-challenged content tends to see declines.
Blogs that generated quality, evergreen content were more likely to benefit from the update than those that focused on short-form, low-quality posts.
