Google's March 2025 Core Update Completed
Google has completed its March 2025 Core Update, finishing a roughly two-week rollout. Google depicted the update as a standard optimization of search results with no major changes, while emphasizing creator content. The period saw notable volatility in rankings, with observers noting shifts across niches and forums; Lily Ray pointed to reduced visibility for many forums (except Reddit), a view supported by SISTRIX CEO Johannes Beus. Some sites experienced traffic declines, others gains, suggesting multiple algorithm refinements converged to drive movement in results. The article also highlights AI-related developments, including AI Overviews rolling out in Germany, which publishers expect to influence how content is summarized and surfaced. SEOs are advised to maintain focus on high-quality content and ongoing analysis, while a potential Spam Update from Google is mentioned as a possible forthcoming factor.

Google Completes March 2026 Core Search Update
Google has finished rolling out its March 2026 Core Update after roughly twelve days, with the rollout declared complete on April 8, 2026. The update follows a short March 2026 Spam Update and arrived amid elevated search volatility. Early analyses show first ranking shifts across verticals and countries: some pages (including certain UGC and original content) report gains while others have dropped. Semrush flagged high desktop volatility in Germany (9.4/10). Google advises site owners to continuously optimize content and site quality and published guidance for large updates; it also exposed new fetcher tooling (a "Google-Agent" user agent) and references AI-related search features such as AI Overviews. Early Semrush data suggests human-written blog content is outperforming some AI-generated content at top positions.

The rollout covers over 200 countries and regions.
