Google confirmed a broad core update on February 1, 2026, and early signals indicate it is one of the most meaningful updates in recent years.
The rollout is clearly doing two things: cracking down on thin, low-value AI-generated content and rewarding sites that demonstrate genuine topical authority.
This update brings to a head a series of algorithmic changes throughout 2025 focused on re-evaluating quality signals at scale, fundamentally changing what it takes to rank in 2026.
February 2026 Core Update: Information Gain Replaces Skyscraper Strategy
The update introduces what experts call Information Gain scoring, which measures how much new information a document provides beyond what is already available online.
Content that simply rephrases existing information will score poorly, while content based on original research, proprietary data, or unique expert insights will rank highly.
The traditional skyscraper content strategy, which involved creating longer versions of existing top-ranking content, no longer works because the algorithm now determines the degree of similarity between competitive pieces.
Content creators must deliver genuinely unique expertise to succeed.

Crawl Efficiency and Technical SEO Priorities
Google recently noted that 75 percent of crawling inefficiencies come from faceted navigation and filtered URLs, including product filters creating endless URL variations and sort parameters that add no unique value.
These pages consume crawl budget without ranking or converting. During the core update rollout, sites that rewrote large sections of content, deleted pages en masse, or made aggressive structural changes mid-rollout historically struggled to recover.
Best practice is to wait at least 14 days after rollout completion before making major SEO decisions. Author profiles, content transparency, and enhanced E-E-A-T signals are now non-negotiable for sustainable search visibility.
