Google March 2026 Core Update Completed

Google has officially confirmed that the March 2026 core algorithm update has been fully deployed globally. This is the second core update of the year, and its impact on foreign trade websites and cross-border e-commerce is already becoming apparent.

Key Changes in This Update

Based on SEO industry data analysis and Google's official announcements, this update focuses on the following aspects:

1. More Detailed Evaluation Standards for AI-Generated Content

Google no longer simply marks AI-generated content as low-quality but evaluates it based on the following dimensions:

• Information Value: Whether the content provides unique insights or useful information
• Editorial Quality: Whether it has been reviewed and edited by humans
• Professionalism: Whether it is created or reviewed by domain experts
• User Experience: Content layout, readability, and page experience

2. Redistribution of Backlink Weight

• The influence of low-quality backlinks is further reduced
• The weight of natural, editorially chosen backlinks is increased
• Purchased links and links from penalized websites may have negative effects

3. Increased Weight for Local Search and E-E-A-T

• Experience, Expertise, Authoritativeness, and Trustworthiness remain core ranking factors
• The weight of localized content has been enhanced

How Foreign Trade Websites Can Assess Impact?

Step 1: Check Traffic Data

Use Google Search Console and Google Analytics to examine:

• Trends in organic search traffic
• Fluctuations in rankings for core keywords
• Changes in traffic to landing pages

Step 2: Diagnose Problematic Pages

If traffic declines, focus on:

• Whether there is a large amount of low-quality AI-generated content
• Whether there are unnatural backlinks
• Whether page experience metrics (Core Web Vitals) meet standards

Step 3: Develop a Recovery Plan

1. Content Upgrade: Add unique insights, data, and case studies to existing content
2. Backlink Review: Clean up suspicious backlinks and build natural, authoritative backlinks
3. Technical Optimization: Ensure page loading speed, mobile adaptation, and structured data
