Google's March 2026 Core Update Shows Major Visibility Shifts Toward Trusted Brands and Official Sources

Aleyda Solis analyzed visibility shifts across US domains during Google's March 2026 core update rollout (March 26–April 11) and identified a consistent pattern: visibility concentrated around fewer, stronger destinations—official sources, specialist sites, well-established brands, and dominant platforms—while intermediary, aggregator, and quick-answer utility sites declined. Dictionary sites like Collins Dictionary (-30.0%), Wiktionary (-21.3%), and OneLook (-52.8%) lost ground to stronger reference destinations like Merriam-Webster and Wikipedia. Similar patterns emerged in jobs (ZipRecruiter and Glassdoor down; direct employer and specialized job boards up), travel (Expedia and Travelocity down; stronger brands consolidated gains), real estate, health, and government sectors. A notable exception was YouTube, which suffered the single largest absolute visibility loss (-24.7%) in the dataset.
