Types of Google Updates
Core Updates are the most significant. They overhaul Google's entire ranking system and can change search results for broad keyword categories. Spam Updates target manipulative practices like link spam, cloaking, or Scaled Content Abuse. Specific Updates affect individual systems like Product Reviews, Helpful Content, or Local Search.
2025 Updates in Detail
The March 2025 Core Update strengthened the weighting of E-E-A-T signals. The June 2025 Core Update emphasized topical authority. The August 2025 Spam Update introduced manual actions against excessively AI-generated content (Scaled Content Abuse). The December 2025 Core Update extended E-E-A-T beyond YMYL and emphasized that weak pages can harm a strong website.
2026 Updates So Far
The February 2026 Discover Update changed content selection for Google Discover. The March 2026 Core and Spam Updates are currently rolling out.
Strategic Approach to Updates
The best protection against negative update impacts is long-term quality. Websites that consistently publish high-quality, user-centered content recover faster from updates or even benefit from them.
When negatively affected: Conduct a content audit, update or remove thin or outdated content, strengthen E-E-A-T signals, and wait for the next Core Update. Google has confirmed that improvements typically only lead to ranking changes with the next Core Update.
